The A14 is a major trunk road in England, running 127 miles (204 km) from Catthorpe Interchange, a major intersection at the southern end of the M6 and junction 19 of the M1 in Leicestershire to the Port of Felixstowe, Suffolk. The road forms part of the unsigned Euroroutes E24 and E30. It is the busiest shipping lane in East Anglia carrying anything from cars to large amounts of cargo between the UK and Mainland Europe.

The M6 motorway is the longest motorway in the United Kingdom. It is located entirely within England, running for just over 230 miles (370 km) from the Midlands to the border with Scotland. It begins at Junction 19 of the M1 and the western end of the A14 at the Catthorpe Interchange, near Rugby before heading north-west. It passes Coventry, Birmingham, Wolverhampton, Stoke-on-Trent, Preston, Lancaster and Carlisle before terminating at Junction 45 near Gretna. Here, just short of the Scottish border it becomes the A74(M) which continues to Glasgow as the M74. Its busiest sections are between junctions 4 and 10a in the West Midlands, and junctions 16 to 19 in Cheshire; these sections have now been converted to smart motorways.
