As part of the Footscray to Deer Park section of the Regional Rail Link project in Melbourne, major road bridge replacements were constructed at Nicholson Street and Albert Street. Both bridges span over the widened rail corridor.The available structural depth was severely restricted at both bridge sites. Unique through-bridge solutions were provided consisting of a bowstring truss at Nicholson Street and Warren truss at Albert Street. Constructability in and around a rail environment with restricted access was also a key constraint.This paper focuses on the unique design features of the two bridges, in particular those features which address space limitation, impact of construction over an operating rail corridor, and aesthetic expectations given the prominent locations of the two bridges.
