The Gateway Motorway is a major tolled motorway in Brisbane, Queensland, Australia which includes the Sir Leo Hielscher Bridges. The motorway is operated by toll road operator Transurban.

The Sir Leo Hielscher Bridges, formerly and still commonly known as the Gateway Bridge, are a side-by-side pair of road bridges on the Gateway Motorway (M1), which skirts the eastern suburbs of Brisbane, Queensland, Australia. The western bridge carries traffic to the north and the eastern bridge carries traffic to the south. They are the most eastern crossings of the Brisbane River and the closest to Moreton Bay, crossing at the Quarries Reach and linking the suburbs of Eagle Farm and Murarrie. The original western bridge was opened on 11 January 1986 and cost A$92 million to build. The duplicate bridge was opened in May 2010, and cost $350 million.
