Hamilton Street Bridge Replacement

We will be replacing the aging Hamilton Street Bridge over the railway line in Subiaco with a new steel and concrete structure.

The old timber bridge was built 99 years ago and has a 5-tonne load limit. Replacing it with a modern structure will ensure it is suitable for all standard vehicles and provide upgraded shared path facilities. It will optimise the road network for local traffic access and pedestrian and cyclist facilities into the future.

Latest news

From 25 February 2019 the Hamilton Street Bridge and adjacent Principal Shared Path (PSP) will close to enable works to begin. The closures are necessary while the old bridge is removed and replaced to ensure public safety.

Detours will be in place to maintain access:

  • Road users will need to access Hamilton Street south of the railway line, Perth Modern and other facilities using the posted detour routes via Haydn Bunton Drive to the west or Loftus Street to the east to move around the area.
  • Path users will be directed away from the existing railway reserve path to a detour using Subiaco Road and White Place returning to the PSP at Loftus Street. 

The project is anticipated to be complete in September 2019. 

Project scope

Replace the existing bridge with a concrete and steel structure that is wider, comprising two 3.5 metre traffic lanes, two 1.2 metre shoulder lanes, and 3 metre paths on both sides.

Improve sight distances and intersection layout at Hamilton Road and Railway Parade.

Upgrade lighting, signage and drainage.

During construction local traffic access will need to be managed as the existing bridge will be closed.



Key benefits

  • Improved traffic flow
