Gateway Motorway:
The Gateway Motorway passes through Brisbane's eastern suburbs, and services mostly residential and industrial areas, both north and south of the Brisbane River. It provides access to ports and the airport.
The Gateway Motorway features dual bridges over the Brisbane River, once known as the Gateway Bridges, but now named Sir Leo Hielscher Bridges, named after an Australian senior public servant and administrator. The bridges operate under an electronic tolling system where motorists pay via a transponder or temporary online account.
The bridges have a number of interesting features including: 2
- A height clearance of 55 m over the high tide mark of the Brisbane River, to allow the largest of ships to pass safely under the bridge.
- A clear span width of at least 230 m so ships of varying size and width could safely manoeuvre under the bridge.
- A maximum 80 m height of the superstructure (including the height of the lamp posts and direction signs) so as not to interfere with flight paths of aircraft taking off or landing at Brisbane Airport.
At the time of its completion, the bridge boasted a number of Australian and world class achievements, including: 2
- The longest cantilevered concrete box girder main river span, at a length of 260 m.
- An erection truss weighing 650 t.
- Stressing cables in the approach spans were the highest loaded cables in a structure in Australia, with 2200 t of 12 mm low relaxation stressing strand.
- Bridge bearings, with a maximum tested load of 4300 t, were the biggest pot bearings made in Australia.
