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.


Current Status - Bridge Demolition 16 to 19 October

The Third Avenue Bridge closed to all traffic in September and demolition is scheduled during a limited rail shutdown from 6pm Friday 16 October to 5am Monday 19 October.

Normal construction noise can be expected during this period, however we will endeavour to minimise disruption as much as possible.

For safety reasons, the existing cycle and pedestrian path will be diverted on Whatley Crescent from Friday 16 October 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.


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

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.
