Drivers in Melbourne’s west will face weeks of pain as a summer construction blitz sees lane closures and diversions in place to widen the West Gate Freeway.

Works will take place around the clock to widen the freeway, which connects Melbourne’s western suburbs to the city, from January 13 until the end of February.

Detours and delays of up to 30 minutes are expected, with signs showing real-time travel information, acting premier Jacinta Allan said on Friday.

“It will be disruptive, but we can’t build the West Gate Tunnel and deliver other vital road upgrades without these works,” she said.

Reconstruction works include Millers Road outbound on and off-ramps to the freeway, the M80 ring road inbound ramp and Geelong Road outbound ramp to the Princess Freeway.

More safety barriers separating traffic from construction work will also be put in place.

“I thank people in the west for their patience over the coming months and encourage them to plan ahead,” she said.

There will also be intersection and road upgrades in Laverton, Kingsville, Truganina and Altona.


* The city-bound ramp from the M80 Ring Road to the West Gate will be closed January 13 to end of February

* Millers Road outbound exit and entry ramps onto to West Gate Freeway closed from January 13 until mid-February
