Two new bridges are being constructed over the Mitchell Freeway as part of the Stephenson Avenue Extension and Stirling Bus Interchange projects.
The project team will use a unique construction method, which will see the bridges progressively built and “launched” from one side of the freeway to the other.
This technique – which uses casting beds, where reinforced concrete bridge sections are poured and cured, before being put into place over live traffic conditions – will mean access to the Mitchell Freeway can be maintained while works are underway.
“People driving along the Mitchell Freeway have probably noticed the significant amount of work happening along this section, but these bridge launches will take things to the next level,” said Transport Minister Rita Saffioti.
“This Stephenson Avenue Extension project is transformational for this part of our city, and will make a big difference to the way people commute and get around.”
Permanent and temporary piers have also been constructed on the freeway, with vehicles shifted onto a temporary alignment while the works take place.
The entire bridge construction process is expected to take around six months to complete.
The Stephenson Avenue Extension project is now more than 40 per cent complete.
Phase one of the project saw Stephenson Avenue extended from Scarborough Beach Road to Howe Street, including two new signalised intersections.
