Construction of original Gateway Bridge, now called "The Sir Leo Hielscher Bridges"

The Sir Leo Hielscher Bridges 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 crossing of the Brisbane River, the closest to Moreton Bay, crossing at the Quarries Reach, between Eagle Farm and Murarrie. The original bridge (formerly named the Gateway 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. (Wikipedia)
