Update six - Acton tunnel damage

ACT Policing is now on the scene at Parkes Way investigating the collision.

ACTION's Route 81 which services the National Zoo and Aquarium, National Arboretum, Black Mountain Tower and the Australian National Botanic Gardens will be diverted via Clunies Ross Street instead of Parkes Way.

Routes 718 and 719 to the Tuggeranong Valley which commence this afternoon from the city at 4.14 pm will be diverted via Commonwealth Avenue and Cotter Road instead of Parkes Way.

The bus stop at Edinburgh Avenue/Rydges Canberra (#4633) will not be serviced during this time by Routes 81, 718 and 719. The alternative bus stop for Route 81 is at the City bus station, Platform 9. The alternative bus stop for Routes 718 and 719 is at the City West bus station, Platform 1.

Passengers should expect delays to travel times due to the diversions and traffic congestion in the area. ACTION recommends that people should incorporate additional travel time into their journey.

No school services are affected.
