Hay Street Bridge

  • Increase the clearance of the bridge over Mitchell Freeway 
  • Work has commenced and is expected to be completed in October 2020.
  • Minimise the risk of the bridge being struck by unauthorised over-height vehicles.

 

Overview

The Hay Street Bridge will be increased by 250 millimetres, over Mitchell Freeway southbound in Perth.

A six metre by 21 metre-long section of the existing bridge will be replaced with a new raised section, and a bridge protection beam will be installed to help minimise the risk of damage if the bridge is struck in the future by unauthorised over-height vehicles.

The bridge was constructed in 1968 and complied with bridge height clearance standards at that time, however, it is now considered a low height clearance structure.

Data shows that the bridge has been hit 20 times, nine of those in the past five years.

Project Update

Two freeway closures in May and June have enabled us to remove a large section of the Hay Street Bridge and complete deconstruction works.

To allow for completion of works, which includes installation of the new raised section and bridge protection beam, additional shorter freeway closures (southbound) are being planned for August.

All out-of-hours works will operate under a Noise Management Plan approved by the City of Perth.
