A Flint & Neill joint venture has won the contract to design the expansion of a bridge in Australia, by adding lanes at its centre rather than on the outside of the current decks.
In addition, the construction will be carried out from an overhead gantry crane above the bridge decks, which the engineering firm said will save time and money, and minimise traffic disruption.
The 518m-long EJ Whitten Bridge in Melbourne currently operates as two separate decks running parallel with a gap in-between. The design will fill the gap with a new deck that will carry four additional lanes, taking the total number of lanes each way from three to five.

The bridge is part of Melbourne’s busy M80 ring road and the overall upgrade project between Sunshine Avenue to Calder Freeway will cost £1.3bn and will entail both the widening and strengthening of the structure.
The client is Vic Roads, the contractor Fulton Hogan and Flint & Neill is part of a joint venture with Arup and Smec. Flint & Neill will also engineer the public safety barriers on the bridge.
“This is an extremely important and necessary project in the region to revitalise the flow of traffic and we are very pleased to be involved,” said Flint & Neill managing director David MacKenzie.
The project is due to be finished by late 2020.
