Light rail is coming – Traffic changes on Commonwealth Avenue


Released 26/07/2023

The ACT Government is hitting another major milestone on extending light rail to Canberra’s south with the imminent opening of a side track over London Circuit.

This new temporary road on the west side of Commonwealth Avenue ensures two lanes of traffic in each direction are maintained during peak hours. It enables the next major phase of the Raising London Circuit project to remove the southbound bridge on Commonwealth Avenue over London Circuit.

It is expected that from around mid-August, drivers heading north on Commonwealth Avenue towards the City will be diverted onto this temporary road across London Circuit.

Canberrans heading south towards the lake will be diverted to the current northbound Commonwealth Avenue bridge over London Circuit.

Once the southbound bridge is removed, fill will be added to build up the eastern side of London Circuit. New permanent southbound lanes will be built on the raised section and another side track will be built on the eastern side.

Further traffic changes on Commonwealth Avenue are expected late this year, or early next year with northbound traffic to be diverted to the new southbound lanes and southbound traffic onto the new temporary road. This then allows for the removal of the northbound bridge over London Circuit.

“This is a significant milestone for the project as we start to see London Circuit being raised by six metres to be level with Commonwealth Avenue, which is essential to bring light rail to Commonwealth Park and then down to Woden,” said Minister for Transport Chris Steel.

“By using temporary roads to divert traffic, we can get work done whilst minimising disruption to Canberrans.

“When complete, a raised London Circuit will create a safer environment for cyclists and pedestrians, but we’ll also ensure access for riding and walking are provided during construction.

“In this next stage there will be a shared path separated from the vehicle lanes by traffic barriers on the western side track, as well as a cyclist lane heading southbound next to the diverted southbound traffic lanes.

“We said this project will be particularly disruptive this year and with this significant traffic change we urge all road users to be alert, slow down, follow traffic signs in the area, allow additional travel time and plan their journey.

“If you need to travel into the city, rethink your routine and consider doing it outside peak times, use public transport, active travel or use the Park and Ride or Bike and Ride facilities across Canberra.”

As construction continues, there will also be more trucks in and around the city, so Canberrans should continue to exercise care.

To facilitate the opening of the side track, a full closure of Commonwealth Avenue between Parkes Way and Vernon Circle is expected to be in place from 6pm Sunday to 6am Monday – the day before the traffic switch starts operations.

Detours will be in place via Parkes Way to access the city, or alternatively Canberrans travelling from South Canberra can use Kings Avenue Bridge.
