Constructed in 1968, the Hay Street Bridge complied with bridge height clearance standards at that time. However, data indicated that the bridge was hit 20 times by over-sized vehicles, nine of those during the past five years to 2020.

BG&E provided structural and civil engineering services for the Hay Street Bridge vertical clearance over the Mitchell Freeway southbound, in particular, our highly-experienced team designed a solution to raise the height of the bridge by 250 millimetres, replace a 21-metre section with a raised section, and added a bridge protection beam.

Upon completion of this multi-million dollar project, the bridge met the current clearance standards (of the transport authority) and improves safety for road-users.
