The Princes Freeway Geelong-bound off-ramp to Palmers Road will be shut down for three days this week, as construction crews work to widen the road.

The off-ramp will be shut from 8pm Friday, April 12 to 6am Monday, April 15. Detours will be in place for some of this time.

The widening works will take place as part of the state government’s $1.8 billion Western Roads Upgrade.

Major Road Projects Victoria project director Frank De Santis said the work formed a “crucial part” of the wider project to upgrade Dunnings and Palmers roads.

“We’ll also work at the Palmers Road and Wallace Avenue intersection, and will demolish the centre island to prepare for new traffic lights to be installed,” he said.

This work will take place across five days until Thursday, April 18, with traffic controllers on site (the works could occur across consecutive days, or on separate days).

Upgrades will also start at the intersections of Palmers Road and The Strand, and Dunnings and Palmers roads, before April 18.

Road crews will work from 7am to 5pm, and detours will be in place at The Strand intersection during these hours.

Mr De Santis said the project would see extra lanes added in each direction on Palmers Road and Dunnings Road, which are used by more than 18,000 vehicles every day.

“We know disruptions can be frustrating at times, and we thank drivers for their continued support as we deliver these important upgrades as swiftly and safely as we can,” Mr De Santis said.

The Western Roads Upgrade is being delivered by Major Road Projects Victoria, in partnership with Netflow. More than 1100 workers are helping deliver the Western Roads Upgrade, which is due to be completed by 2021.
