Tuggeranong Parkway will be down to one lane during off-peak traffic times over the coming weeks for bridge strengthening works.
A Transport Canberra and City Services spokesperson said the works will take place on the Tuggeranong Parkway where it crosses the Molonglo River, in both directions, near the Cotter Road ramps.
The works are part of the Federal Government’s Bridges Renewal Program, an initiative to improve the productivity and safety of heavy vehicle operations through upgrading bridge load capacities. Works include the construction of four new concrete bridge piers beneath the existing bridge deck and strengthening of the existing piers to allow B-Doubles to travel along the bridge.
The spokesperson said the majority of works, which commenced today and will run through until the end of the year, will be undertaken beneath the bridge without any impact to traffic travelling on the Tuggeranong Parkway.
However, portions of the work will require lane closures to ensure the safety of workers and the speed limit will be reduced from 100 km/h to 40 km/h.
All lanes will be open during peak-hour traffic, but off-peak lane closures will take place from today (8 October) to next Wednesday (16 October), and from 21 to 29 October, as well as from 18 to 29 November.
Barriers, as well as warning and diversion signs, will be erected to alert people to the temporary lane closures. Drivers are asked to be mindful of the changed traffic arrangements and adhere to the work zone speed limit of 40 km/h.
Delays are expected.
