The Western Port Highway isclosed to traffic until 5am Monday 4 April as crews prepare to replace the roundabouts with traffic lights at the Cranbourne-Frankston Road and Ballarto Road intersections.
Crews will work 24/7 to install temporary lighting and safety barriers, remove the existing road surface, relocate underground services, excavate to make way for additional lanes, and complete temporary asphalt and line marking.
During works, the Western Port Highway will be closed to through traffic between Hall Road and North Road.
Cranbourne-Frankston will be closed between Pearcedale Road and Potts Road/Centre Road, while Ballarto Road will be closed between Encore Boulevard and Potts Road.
There will be limited local access available for residents and route 791 buses along Cranbourne-Frankston Road, under the direction of traffic controllers.
Significant detours will be in place for heavy vehicles and through-traffic during the closure of this important freight link, via the South Gippsland Highway, Baxter-Tooradin Road, Peninsula Link, Frankston-Dandenong Road, as well as Thompson and Thompsons roads.
Drivers are encouraged to plan ahead and to allow up to 30 minutes extra for their journey during peak times.
Following these works, reduced speed limits will be in place with smaller, temporary roundabouts installed, allowing crews to continue with upgrade works.
The Western Port Highway Upgrade, which will replace the roundabouts at Ballarto Road and Cranbourne-Frankston with traffic lights, is expected to be completed by the end of 2022.
