Bridges

The Regional Rail Link (RRL) project involves the construction of new regional tracks from Southern Cross Station in Melbourne, through to Sunshine, then west to Werribee. Within the Footscray to Deer Park section of the project, major pedestrian bridge works were undertaken at Nicholson Street and HV McKay Reserve to replace existing bridges by new structure spanning across the enlarged rail corridor. This section of the works was delivered by an alliance consisting of Balfour Beatty, Metro Trains Melbourne, Parsons Brinckerhoff, the Regional Rail Link Authority, Sinclair Knight Merz, Thiess and V/Line. The architectural input for the design was provided by Hassell Studio.This paper focuses on the special design features of these two pedestrian bridges in the brownfield environment, including the impact of installation in an operating rail corridor, limitations in space and operating conditions imposed due to the location of the bridges, aesthetically pleasing design and the dynamic analysis involved in the design.
