M1 to get variable speed limits to help ease gridlock

The State Government is set to introduce variable speed limits on the M1 to try and help ease congestion on the busy motorway.

It follows a review into a number of initiatives that were introduced for the 2018 Commonwealth Games.

The maximum speed limits of 100 and 110 will remain in place when traffic is quiet, but new signs will be installed to allow authorities to reduce the limit after an accident or when there is congestion.


Transport and Roads Minister Mark Bailey says it depends on the incident as to when the variable limits would be used.

“It could be someone’s had a crash that needs to be managed, it could be bad weather or it could be a range of real-time scenarios,” Mr Bailey said.

“Of course the M1 is watched and monitored 24 hours a day, 7 days a week so if we see congestion that needs dealing with then variable speed limits coming down will help.”

Mr Bailey says the measure has worked in other parts of the State.

“This has reduced the morning peak on the Bruce Highway from 4.5 hours down to 2 hours by having variable speed limits during those congested periods,” he said.

Other measures that were introduced for the Commonwealth Games will now become permanent features including restricting trucks to the left hand lanes.

Ramp metering that was introduced for the Games at several M1 on-ramps will also remain in place.

Minister Bailey says the measures would also be rolled out on all of the motorway upgrades at the Gateway Merge and between Mudgeeraba and Varsity Lakes once they are completed.
