Third Avenue Bridge



We are building a new Third Avenue Bridge over the railway in Mount Lawley, which is expected to be opened to traffic by mid-2016.

Funded by the State Government, this new bridge is the second stage of a project to improve safety and efficiency on the local road and rail network.  Staggered to minimise disruption to road users and local community, the project started with replacement of the Seventh Avenue Bridge, which opened to traffic in May 2015.

On 22 & 23 January, four steel beams and 48 precast concrete panels that will form the new bridge deck were craned into place.

The project is on schedule for completion by the end of April. 


Project Scope

The new concrete Third Avenue Bridge will have a single span of about 22 m.  It will be built to meet current safety standards and have no weight restrictions.  Twice as wide as the old timber bridge built in 1910, it will include a second lane eastbound to separate traffic turning left and right onto Whatley Crescent and improve traffic flow at peak periods. 


Construction Impacts

From late February, traffic management will also be in place along Whatley Crescent to facilitate drainage and pavement works.  This may result in occasional traffic delays outside of peak hours.

While every effort is being made to minimise the impact of the project, road users and residents should expect some disruption and delays during construction of the new bridge.

Whatley Crescent and Railway Parade have been reduced to 40 km/h through the construction zone.

Motorists are encouraged to seek alternative routes and allow extra travel time as delays around the area are expected.  Access between Railway Parade and Whatley Crescent is available via the Railway Parade Bridge, Seventh Avenue Bridge and Caledonian Avenue level crossing.

Most of the work is being carried out from 7am to 7pm Monday to Saturday, however some after hours works are planned during demolition and rail shutdowns.

For safety reasons, the existing cycle and pedestrian path has been diverted on Whatley Crescent and will remain in this location until late March 2016, when it is rerouted through a new 30 m underpass. Path users may experience minor delays during the bridge demolition.
