Highway system

Tonkin Highway is a 51-kilometre-long (32 mi) north-south highway and partial freeway in Perth, Western Australia, linking Perth Airport and Kewdale with the city's north-eastern and south-eastern suburbs. As of September 2019, the northern terminus is at The Promenade in Ellenbrook,[2] and the southern terminus is at Thomas Road in Oakford, it forms the entire length of State Route 4, and connects to several major roads, including Reid Highway, Great Eastern Highway, Leach Highway, Roe Highway, and Albany Highway.

Planning for the route began in the 1950s, but the first segment between Wattle Grove and Cloverdale was not opened until 1980. Over the next five years, the highway was extended north to Great Eastern Highway and south to Albany Highway, and a discontinuous section was constructed north of the Swan River. In 1988 the Redcliffe Bridge linked these sections, and three years later, Reid Highway became the northern terminus; the next major works on the highway, between 2003 and 2005, extended the highway south to Thomas Road.

The central section of Tonkin Highway was upgraded to a six-lane freeway-standard road between 2013 and 2015, as part of the Gateway WA project to improve the wider road network around Perth Airport. Beginning in 2016, construction commenced to also upgrade the northern section of Tonkin Highway to a six-lane freeway-standard road, and to build a highway standard road from the highway's current northern terminus in Malaga to Muchea, as part of the NorthLink WA project. Planning provisions have been made for Tonkin Highway to be extended south of Byford in the future.

Route description[edit]

Tonkin Highway forms the entire length of State Route 4, it is a dual carriageway road maintained by Main Roads Western Australia, and subject to control of access[note 1] along its entire length.[5][6] Some junctions on the highway are at-grade and traffic light controlled; however, all junctions north of Hale Road in Wattle Grove and junctions with Albany Highway and Corfield Street in Gosnells, are freeway-standard with grade-separated interchanges; the central section of the highway between Reid Highway and Roe Highway is primarily six lanes wide; the remainder of the highway is primarily four lanes wide.[1] The speed limit is 80 kilometres per hour (50 mph) near at-grade intersections, and 90 or 100 km/h (55 or 60 mph) along the stretches in between.[6] A shared pedestrian and bicycle path is built alongside part of Tonkin Highway, between Collier Road and Great Eastern Highway, as well as south of Mills Road East. In most other sections, the highway's sealed shoulders also function as bicycle lanes.[7][8][9]

Main Roads Western Australia monitors traffic volume across the state's road network, including several locations along Tonkin Highway;[10]:3 the section near Perth Airport, south of Great Eastern Highway, is the busiest, averaging over 56,000 vehicles per weekday in 2007–08, and over 57,000 in 2008–09. North of the Swan River, the traffic volume gradually decreased to under 40,000 vehicles per weekday near the northern terminus, in 2007–08. Measurements in 2008–09 showed the lowest volume to be under 10,000 vehicles per weekday near the southern terminus, north of Thomas Road.[10]:73–74

In 2013, immediately preceding the upgrade of Tonkin Highway's central section to a six-lane freeway-standard road, junctions in and around Kewdale, Forrestfield and Perth Airport carried traffic volumes beyond their capacity during peak periods.[11] Average peak period traffic speeds in this part of Tonkin Highway were measured as 20 km/h (12 mph) or less in 2013; the slowest section was from Leach Highway to Horrie Miller Drive, which recorded an average of 14 km/h (9 mph) during the afternoon peak period.[12] Traffic volume, exceeding 50,000 vehicles per day in 2012, is forecast to almost double by 2031. Traffic modelling showed that leaving the current network of traffic light controlled intersections in place would have resulted in gridlock by 2021. Following the completion of the Gateway WA project in 2015, the upgraded road network is forecast to have an average speed in peak periods of between 55 and 75 km/h (35 and 45 mph) in 2021.[13]

North of the Swan River[edit]

View south along Tonkin Highway in Noranda

Tonkin Highway begins at Gnangara Road on a section of the former Beechboro Road North in Cullacabardee, within the City of Swan local government area (LGA); the highway heads south forming the border between the residential suburbs of Beechboro and Noranda. After 150 metres (490 ft), the highway wholly enters the City of Bayswater LGA. East of the highway, the LGA boundary is also the boundary between the suburbs of Beechboro and Morley. The highway travels south for 400 metres (0.25 mi) to Benara Road, which Tonkin Highway passes under. The south-eastern corner of Noranda is 400 metres (0.25 mi) south of the flyover, leaving the highway entirely within Morley. Tonkin Highway continues south through the residential area for 1.1 kilometres (0.68 mi), and reaches a roundabout interchange, with Morley Drive and Morley Drive East.[14][15]

Tonkin Highway continues southwards through a narrow S curve that realigns the highway further east. Partway through the curve, 800 metres (0.50 mi) south of Morley Drive, the highway passes under Broun Avenue, though there is no access between the roads. At this point the highway enters the north-eastern corner of Embleton, travels through it for 400 metres (0.25 mi), and then enters Bayswater. The border between Embleton and Bayswater follows Beechboro Road, which is discontinuous either side of Tonkin Highway; the highway continues through Bayswater, between residential housing to the north-east and an industrial area to the south-west. After 500 metres (0.31 mi) the S curve ends, with the highway now travelling between industrial and commercial properties. There is another interchange, this time a single-point urban interchange 400 metres (1,300 ft) further south, with Collier Road; the next major road the highway meets is Guildford Road, 1.7 kilometres (1.1 mi) further south. It is connected via a grade-separated interchange folded diamond interchange, with all the ramps located south of Guildford Road; to the north is the Midland railway line, and the parallel road Railway Parade, which the highway passes over. From here the highway turns south-easterly, perpendicular to the Swan River, and travels through another residential part of Bayswater for 1.2 kilometres (0.75 mi). Tonkin Highway crosses the river via the 270-metre-long (890 ft) Redcliffe Bridge, which takes the highway into Ascot, in the City of Belmont LGA.[14][15]

Perth Airport[edit]

A grade-separated interchange with Great Eastern Highway is located 350 metres (1,150 ft) south-east of the Redcliffe Bridge, it is a diamond interchange, with an additional eastbound to southbound looped entry ramp. Previously, Great Eastern Highway's intersection with the southbound exit ramp also connected to Brearley Avenue which, until September 2018, provided one of the main access roads to Perth Airport's domestic terminal; however Brearley Avenue was closed to allow construction on the Redcliffe railway station . Beyond this interchange, Tonkin Highway, now six lanes and freeway standard, is within Redcliffe's residential areas. A further 750 metres (0.47 mi) takes the highway to the edge of the suburb of Perth Airport, where it becomes the border between Redcliffe to the south-west and Perth Airport to the north-east. Five hundred metres (0.31 mi) later, the highway approaches the interchange with Dunreath Drive.[16] A dogbone interchange, Dunreath Drive replaced the Brearley Avenue entrance as the main access road from Tonkin Highway to Perth Airport's domestic terminal in 2015.

After 0.5 kilometres (0.31 mi), the highway turns south, travelling in that direction for 1.1 kilometres (0.68 mi) before reaching Cloverdale and curving back to the south-east, meeting Leach Highway and Airport Drive. Known as the Grand Gateway interchange, it is the primary access to Perth Airport's international terminal (replacing Horrie Miller Drive in 2015), it is a modified three-level cloverstack interchange with two loop ramps (Airport Drive west to Tonkin Highway north and Leach Highway east to Tonkin Highway south).[17] These movements, along with another five of the eight available between the three roads are free-flowing. Only Tonkin Highway north to Leach Highway west is controlled by traffic lights at the subsequent Leach Highway/Abernethy Road interchange before entering the highway itself to minimise the danger posed by weaving; the interchange is only 13.9 metres high, its height limited by the airport runway to its north with tunnelling not possible due to the high water table in the vicinity.[18] It is located at the borders between three suburbs: Cloverdale to the west, Kewdale to the south, and the Perth Airport to the north-east.[14][16]

Beyond Leach Highway, Tonkin Highway continues past industrial properties for 1.3 kilometres (0.81 mi), reaching the interchange with Kewdale Road to the south-west, and Horrie Miller Drive to the north-east. Now a single-point urban interchange, the initial signalised intersection was the original primary access road for Perth Airport's international terminals. Horrie Miller Drive now serves the industrial areas south of the terminal, and provides a secondary access to the terminals. After another 1.4 kilometres (0.87 mi), the highway reaches Abernethy Road. The only connections are a north-westbound looped exit ramp that merges with a local road, McDowell Street, north of Abernethy Road and a south-eastbound entrance ramp built in 2014.[19] Beyond this intersection, the highway enters the City of Kalamunda LGA, and is the location of the border between the suburbs of Kewdale to the south-east and Forrestfield to the north-east. It continues along the border for 900 metres (0.56 mi), until it reaches Roe Highway, which marks the border between Kewdale and Wattle Grove, on the south-western side of Tonkin Highway.[14][16] Initially built as a signalised diamond interchange favouring Tonkin Highway, the Gateway WA project has since modified the connection into a hybrid diamond-stack interchange, with all Tonkin Highway southbound movements free-flowing, along with both left turns from Roe to Tonkin Highway.[20]

Forrestfield to Oakford[edit]

Tonkin Highway travels in a south-easterly direction between residential areas in Forrestfield and Wattle Grove, reaching Hale Road after 1.2 kilometres (0.75 mi). Over the next 1.5 kilometres (0.93 mi), the highway curves back to the south. At this point it intersects Welshpool Road East, and is entirely within the suburb of Wattle Grove. Beyond this intersection, Tonkin Highway continues south-east as the border between the semi-rural areas of Kenwick to the west, and Wattle Grove to the east. This is also the border between the City of Gosnells and City of Kalamunda LGAs, which the highway follows for 1.9 kilometres (1.2 mi). It then reaches the suburbs of Maddington, located west of the highway, and Orange Grove, east of the highway, and from this point on, is entirely within the City of Gosnells. After 750 metres (0.47 mi), the highway crosses Kelvin Road, and continues south-east for a further 2.8 kilometres (1.7 mi). It briefly passes the industrial part of Maddington, before curving slightly around an urban development to reach intersections with Gosnells Road East, and subsequently Gosnells Road West; these are a pair of T-junctions, 260 metres (850 ft) apart, which are not traffic-light controlled. Tonkin Highway follows a gentle reverse curve southwards through Martin for 2.1 kilometres (1.3 mi), once more within a semi-rural environment, before reaching a set of traffic lights with Mills Road East and West. Tonkin Highway crosses the Canning River 1.4 kilometres (0.87 mi) further south, entering Gosnells. It then curves south-west towards Albany Highway, 650 metres (0.40 mi) away.[14][21]

Approach to the current southern end at Thomas Road, Oakford

Tonkin Highway meets Albany Highway at a folded diamond interchange; the highway splits into local and express lanes on approach to this interchange, and continues in this configuration for 600 metres (0.37 mi). At this point there is a dogbone interchange with Corfield Street, with the highway now marking the boundary between the suburbs of Gosnells and Champion Lakes, as well as the City of Gosnells and City of Armadale LGAs. It continues south-westbound, passing between Champion Lakes to the south-east, and undeveloped land to the north-west. After 3.3 kilometres (2.1 mi), there is a T junction with Champion Drive. The highway continues southwest for another 2.7 kilometres (1.7 mi) until it reaches a set of traffic lights with Ranford Road. Afterwards it is entirely within the City of Armadale LGA, and the suburb of Forrestdale. Tonkin Highway turns south, along a two-kilometre-long (1.2 mi) curve, and meets Armadale Road at another set of traffic lights. The highway continues south through rural land, between Forrestdale to the west, and Haynes and Hilbert to the east. It passes Forrest Road after 1.5 kilometres (0.93 mi), only connecting to the eastern leg at a T junction, and 2.2 kilometres (1.4 mi) further on, reaches Rowley Road. Following this traffic controlled intersection, Tonkin Highway is within the Shire of Serpentine-Jarrahdale LGA; the highway follows the eastern edge of Oakford for 3.2 kilometres (2.0 mi), past low density residential lots. Tonkin Highway ends at Thomas Road, which connects traffic to Kwinana Freeway and South Western Highway.[14][22]

A proposal for a highway along a similar alignment was first proposed in 1955, as part of a network of arterial roads under a metropolitan-wide plan produced for the Western Australian government by Gordon Stephenson and Alastair Hepburn; the road reservation was formally gazetted in the 1963 Metropolitan Region Scheme.[23]:282 It was first named "Beechboro-Gosnells Highway", the name coming from the two suburbs it was originally planned to link.[23]:311 Like most Perth arterial road projects, the highway was built in stages,[23]:311 it was initially constructed as a 3.3-kilometre-long (2.1 mi) dual carriageway, from Welshpool Road, Wattle Grove to Hardey Road in Cloverdale, which opened on 16 June 1980. A further 12.2 kilometres (7.6 mi), that linked the new highway to Albany Highway in Gosnells, was completed in December 1980.[23]:282–3 This $6.1 million section, which officially opened on 22 December 1980,[24] was the start of a new route between Gosnells and Bellevue,[note 2] and reduced traffic volume and congestion on Albany Highway.[23]:283

The third segment to be constructed was a 3.6-kilometre-long (2.2 mi) section north of the Swan River, from Railway Parade in Bayswater to Morley Drive, which opened on 11 July 1984.[23]:311 [24] This $3.5 million section was constructed by Thiess Contractors Pty Ltd, with Taylor Woodrow International Ltd responsible for constructing the Broun Avenue bridge.[25] Stage 4 linked Hardey Road and Great Eastern Highway, and included the construction of four bridges over the Forrestfield railway marshalling yards, the first bridges in Australia to be constructed using the incremental launch technique.[23]:311 Upon opening on 1 May 1985, Beechboro-Gosnells Highway was renamed "Tonkin Highway", in honour of former Western Australian premier John Tonkin. Tonkin had also been the Minister for Works during the planning and construction of the Narrows Bridge and Kwinana Freeway in the 1950s.[23]:311 A ceremony was held at Redcliffe on 1 May by the Premier Mr Brian Burke, who unveiled a plaque. Mr Tonkin, who at the time was aged 83, cut the ribbon at the ceremony to officially open the new Forrestfield to Redcliffe section of the highway.[26] A grade-separated interchange was constructed at Great Eastern Highway in 1986, which included a six lane road bridge over Tonkin Highway and a pedestrian subway,[23]:312 it was constructed earlier than initially planned, as heavy traffic from Perth Airport was expected during the 1987 America's Cup.[23]:312

View south along Tonkin Highway, from the Redcliffe Bridge to Great Eastern Highway

Construction on a link between the northern and southern sections of Tonkin Highway began in 1988. Included in this $48 million stage was the Redcliffe Bridge over the Swan River, and an interchange with Guildford Road, north of the bridge;[23]:312 the 270-metre-long (890 ft) Redcliffe Bridge, also built using the incremental launching technique, was designed to carry six traffic lanes, as well as pedestrian and cycle paths that could be converted into traffic lanes when required. The bridge deck is supported by a narrow central section with cantilever extensions on each side, as a "big heavy bridge would have looked out of place"[23]:360 at a relatively narrow section of the river; the bridge opened on 16 April 1988, and received awards for engineering excellence from both the national and state branches of the Institute of Engineers, Australia.[23]:359–60

The highway was then extended northwards, reaching Benara Road on 18 December 1989, and Reid Highway on 11 November 1991.[24] Tonkin Highway spent a decade remaining largely unchanged, linking Reid Highway in Malaga with Albany Highway in Gosnells. In 2003, construction of a new southern extension commenced. Planning and Infrastructure Minister Alannah MacTiernan and the Member for Roleystone, Martin Whitely, participated in a sod turning ceremony on 27 June 2003, to mark the start of the project. At the time, the $140 million extension was the largest single road project in Western Australia; the project was completed in two stages, with Armadale Road as the midpoint.[27] The first 11-kilometre-long (6.8 mi) section, including a new interchange at Albany Highway, was opened by Premier Geoff Gallop and Alannah MacTiernan on 2 April 2005.[28][29] The original connection to Albany Highway was renamed Ferres Drive;[30] the Forrestdale Business Park and the Champion Lakes precinct were constructed concurrently with the project, to encourage industrial and residential development alongside the new highway section.[28] The remaining seven kilometres (4.3 mi), from Armadale Road through to Thomas Road, opened a year ahead of schedule on 16 December 2005.[24][31] The new extension improved links with Kwinana, Armadale, Rockingham and Byford, it also provided a new freight route, diverting heavy vehicle traffic away from the existing road network and residential areas.[28][31]

On 16 April 2012, an intersection with Dunreath Drive was opened;[24][32] this traffic light controlled at-grade intersection allowed access to and from the international terminal of Perth Airport, bypassing Tonkin Highway's intersections with Leach Highway and Kewdale Road/Horrie Miller Drive.[33] The intersection was later removed on 16 July 2015 upon the commissioning of two nearby interchanges as part of Gateway WA.[34]

Gateway WA[edit]

At-grade intersection of Tonkin and Leach Highways in 2013

Between 2014 and 2016, the $1 billion Gateway WA Perth Airport and Freight Access Project was undertaken to upgrade the road network around Perth Airport. At the time it was the largest project Main Roads Western Australia had ever undertaken, covering the upgrade of Tonkin and Leach highways, and the construction of four new interchanges; the project was jointly funded by state and federal governments, which provided $317.5 million and $686.4 million respectively.[19]

As part of the project, Tonkin Highway was expanded from two to three lanes in both directions, between Great Eastern Highway and Roe Highway, with the existing intersections in this section becoming grade separated. A new diamond interchange was constructed with Dunreath Drive to provide access to the domestic terminal precinct, replacing Brearley Avenue as the main access to the precinct. International terminal access was provided via a new freeway-to-freeway cloverstack interchange at Leach Highway, and a single-point urban interchange at the intersection with Horrie Miller Drive and Kewdale Road; the existing diamond interchange with Roe Highway was upgraded to a partial freeway-to-freeway interchange, but with plans to further upgrade it to a completely free-flowing interchange in the future.[19][35]

In January 2013, works were undertaken to protect or relocate sections of the Canning Trunk water main and the Dampier to Bunbury Natural Gas Pipeline in the vicinity of the project.[36] Construction on the Gateway WA project officially began on 1 February 2013 with a groundbreaking ceremony attended by the state and federal transport ministers, Troy Buswell and Anthony Albanese; the whole project was due to be completed by 2017.[36] However it was moved to March 2016, due to construction moving faster than expected.[37] Works were finished on April 12, 2016.

Intersection Upgrades[edit]

During 2016, the intersection with Gosnells Road West was upgraded with longer and extra turning lanes, better cycling and pedestrian facilities, and better street lighting and CCTV as part of the Black Spot program; this project was funded by the Western Australian State government, and cost $2.4 million.[38] During 2016 and 2017, as part of Main Roads Western Australia's Traffic Congestion Management Program, the intersection with Kelvin Road was upgraded to improve traffic flow and safety. New and longer turning lanes were added; this project cost $7.5 million and was funded by the Western Australian state government.[39]

Future works[edit]

A number of improvement works are planned for Tonkin Highway, which will see most of the central and northern sections upgraded to a freeway-standard road with grade separated interchanges.[19][40] Extensions are also planned at both ends of the highway, which would see the southern end extended to South Western Highway south of Byford, and link the northern end to the future Perth Darwin National Highway (PDNH) near Ballajura.[41][42]

Southern extension[edit]

Tonkin Highway reaches past the edge of suburbia at its southern extent. Planning provides for it to be extended when required; the initial plans indicated the extension would continue south through undeveloped or semi-rural areas such as Mundijong, Cardup and Jarrahdale. South of Mundijong, the planned route would deviate east to terminate at South Western Highway near Jarrahdale Road, which would then be upgraded.[43][44]:1 Following the 2001 state election, the new government abandoned the Jarrahdale Road option, preferring a shorter route that deviated to South Western Highway near Orton Street, closer to Byford.[44]:2 In July 2012, seven years after the previous extension was completed, the Minister for Transport announced the formation of a community working group to investigate an extension of Tonkin Highway beyond Thomas Road; the group met several times to identify and evaluate possible solutions to traffic congestion in the area, and prepare a strategic business case for the next extension.[41] As of 19 February 2013, the preferred options are to extend the highway to South Western Highway, at a location either south of Lakes Road or south of Mundijong Road.[45]

The long term plan for Tonkin Highway extending southwards, outlined in Perth's transport at 3.5 million plan is for Tonkin Highway to be eventually extended as a freeway standard link to Forrest Highway south of Pinjarra, but no planning has been done for this, and the transport plan has said that this is very far off in the future, and is unlikely to happen until after 2050.[46]

NorthLink WA[edit]

NorthLink WA is a project that will see both the northern section of Tonkin Highway upgraded, and the road extended northwards to bypass Great Northern Highway within Perth; these two component projects are separately funded, with both the state and federal governments contributing to each project. Construction began in 2016, and is scheduled to be completed by 2019.[47]

Intersection Upgrades[edit]

The federal government has allocated $140.6 million to grade-separate Tonkin Highway's intersections with Benara Road, Morley Drive and Collier Road. The funding is part of the next five-year phase of the Nation Building Program, from 2014–15 to 2018–19; the upgrades are intended to improve freight transportation along the highway.[40] The total cost is expected to be $281.2 million.[48] In the lead up to the 2013 Australian federal election, which resulted in a change of government, Labor candidate for Perth, Alannah MacTiernan, accused the then-opposition's candidate of lying to the electorate over their commitment to the upgrade;[49] the official policy costings did not contain specific funding for the project. However, an opposition spokesperson claimed it was "in the current forward estimates", and not in the costing, as the upgrade was neither a "new and accelerated" project, nor a project that would definitely not be funded.[49]

Northern extension[edit]

Construction started in June 2017 to extend Tonkin Highway north, past Ellenbrook and through the Swan Valley to Brand Highway and Great Northern Highway in Muchea. Interchanges are planned at junctions with Reid Highway, Hepburn Avenue and Beechboro Road North, Gnangara Road, The Promenade, Stock Road, Neaves Road and Brand Highway and Great Northern Highway;[50] the third stage was originally planned to be a two-lane single-carriageway road with at-grade intersections, with provision for upgrading in the future. However during the tender process it was found that the ultimate plan with a four-lane highway and grade separation could be completed within the existing budget; the previously planned route of the PDNH, prior to 2012, followed Lord Street, east of Whiteman Park.[51] Construction is due to be completed mid 2019[needs update].[52]
