Premier Daniel Andrews joined Cranbourne MP pauline Richards at the site of the Hall Road Upgrade on Wednesday 11 April.
The intersection construction blitz continues with closures upcoming from 7pm Friday 28 April until 5am Monday 26 June.
As part of the Hall Road Upgrade, the intersections of Evans and Cranbourne-Frankston roads in Cranbourne West will be realigned to create a single safer intersection.
The project will convert the intersections at Cranbourne-Frankston and Hall roads and Evans and Hall roads into a single four-way intersection with traffic lights.
Extra lanes will be added to increase capacity and improve traffic flow for the 30,000 vehicles that travel along Hall Road each day.
The intersection closures will fast-track major construction.
During this time, Cranbourne-Frankston Road will be closed in both directions between Willow Glen Boulevard and Ranfurlie Boulevard.
Hall Road will be closed between Cranbourne-Frankston Road and just before Banyan Drive.
Evans Road will remain closed between Hall Road and Strathlea Drive.
Crews will work 24/7 to complete three months of work in just eight weeks.
This is the last stage of major works to build the new intersection.
Works include the relocation of water and telecommunication services, completion of earthworks, installation of stormwater drainage and completion of new shared walking and cycling paths.
Arterial detours will be in place via Thompsons Road, Western Port Highway, South Gippsland Highway, North Road and Craig Road.
Delays of up to 30 minutes are expected.
Motorists are advised to plan ahead and consider travelling outside of peak periods where possible.
The new signalised intersection is expected to be open to traffic on 26 June.
The Victorian and Commonwealth Governments have invested $282.5 million to add lanes and upgrade key intersections along Hall Road between McCormicks Road and Cranbourne-Frankston Road.
The project will increase the number of traffic lanes on Hall Road to two lanes in each direction between McCormicks Road and Western Port Highway.
Once complete, the project will improve journeys along Hall Road and make it safer and more accessible for Cranbourne locals and the broader community to access local community facilities.
This project, together with the Camms Road level crossing removal, the Narre Warren-Cranbourne Road Upgrade, and the recently completed upgrade of Western Port Highway at Ballarto and Cranbourne-Frankston roads, aim to improve cross-Cranbourne traffic flow and removing bottlenecks across the south east.
