Boundary Street rail bridge replacement, Roseville

RailCorp’s new Boundary Street Bridge in Roseville, on Sydney’s North Shore, is a 3,500 tonne superstructure built to facilitate future growth and represents best practice in the delivery of essential infrastructure. With the bridge carrying one of Sydney’s busiest railway lines, and the heavily trafficked Boundary Street underneath the structure, construction was limited to a set number of railway possessions to minimise the impact on live road traffic and the Epping to Chatswood Rail Link tunnels eight metres beneath the bridge site. Maximising the use of precast elements and building the core of the new bridge adjacent to the existing bridge and sliding it into place, the impact on the rail and road users was minimised. The integral connection between the substructure and superstructure achieved post slide maximised the structural capacity by incorporating the temporary works into the permanent works.
