Project Description

The project involved the construction of a grade-separated interchange at the intersection of the Roe Highway and Berkshire Road in Forrestfield, to replace an intersection which consists of two staggered T-junctions, with the South junction under traffic signal control and the North junction under sign control.


The project is expected to improve traffic flows and safety on the Roe Highway, which is a critical freight connection on the Perth Urban Transport and Freight Corridor of the National Land Transport Network.

The upgrade to a grade-separated interchange is intended to reduce congestion and improve safety at this intersection, which has a poor crash record.


The Australian Government provided $27.2 million from the Infrastructure Investment Program and $8.82 million from the GST revenue shortfall in 2014-15 towards the $46.2 million project.


Construction commenced in November 2014 and was completed in March 2016.
