A 1km exclusion zone has been established around Acton Tunnel on Parkes Way to manage asbestos risk after its collapse this morning. Emergency services are advising Canberrans to expect delays on our roads this afternoon (see below for details of redirections).
The tunnel collapsed after an excavator on the back of a loader ripped 60 metres from the tunnel roof.
The exclusion zone has been established downwind because there appears to be bonded asbestos in tiles at the site.
Engineers are on site assessing the structural integrity of the bridge.
No one has been injured but there are significant traffic delays as Parkes Way is closed in both directions till further notice.
ACT Fire & Rescue and ACT Policing attended the scene having received calls about the accident at 10.20am. Roads ACT is also providing assistance.
A forward command post has been established near Commonwealth Avenue.
There have been no evacuations and there are none anticipated at this stage.
Parkes Way between Clunies Ross Street and Edinburgh Avenue has been closed in both directions until further notice due to an earlier accident.
Road users are encouraged to take an alternative route and plan their journey home.
Westbound traffic leaving the city will be diverted right onto Coranderrk Street, left onto Cooyong Street, straight onto Barry Drive, left onto Clunies Ross Street, Lady Denman Drive and onto the Tuggeranong Parkway.
Traffic travelling westbound from Commonwealth Avenue, onto Parkes Way, will be directed straight through to London Circuit and Northbourne Avenue, left onto Barry Drive, left onto Clunies Ross Street, Lady Denman Drive and onto the Tuggeranong Parkway.
Eastbound traffic heading into the city will be diverted left onto Clunies Ross Street, right onto Barry Drive, straight onto Cooyong Street, right onto Coranderrk Street and back onto Parkes Way.
Electronic message signs will be erected to alert people to the diversions in place.
