Traffic remains backed up on the Parkes Way tunnel after a five-car collision earlier on Thursday. Emergency services have cleared the site but traffic is slow.
Wet weather has resulted in several "minor accidents" across the ACT, an Emergency Services Agency spokesperson said.
As of 7.30pm on Thursday night six car crashes were active on the ESA site in Bruce, Canberra City, Action, Belconnen and Molonglo Valley.
An ACT Policing spokesperson said the car accidents were all minor with no serious injuries or hospitalisations.
Motorists have been reminded to drive to the conditions.
