As works continue to prepare the tunnel for opening, motorists are advised to plan their journey home from the city by leaving early and taking an alternate route.
Westbound lanes on Parkes Way leaving the city remain closed between Clunies Ross Street and Edinburgh Avenue.
The following diversions remain in place:
Westbound traffic leaving the city is being 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, is being 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.
The eastbound lanes of Parkes Way still have a 40 kilometre per hour speed limit in place from approximately 400 metres before the tunnel until just after the tunnel when the speed limit reverts to 80km/h. Motorists are urged to drive with extra care in the area.
