Hay Street Bridge

We are increasing the clearance of the bridge over Mitchell Freeway to minimise the risk of oversized vehicles hitting the bridge. Work has begun and is expected to finish in October 2020.
Hay Street Bridge construction


Hay Street Bridge was built over Mitchell Freeway southbound in 1968. It no longer meets today’s bridge height clearance standards. Trucks have hit the bridge nine times in the past five years.

This project will address this issue by:

  • Increasing the bridge height by 250mm
  • Replacing a 21m long section with a new raised section
  • Adding a bridge protection beam
