Work has started on the Mordialloc Freeway project, which as well as a huge road, will deliver an 8km trail for bike riders and pedestrians.
The Mordialloc Freeway will link the Mornington Peninsula Freeway at Springvale to the Dingley Bypass, creating a continuous freeway from Frankston to Clayton.
The contract was awarded to the McConnell Dowell and Decmil Joint Venture.
The trail will create a continuous route from Dingley Village to Aspendale Gardens, connecting to existing paths at the Dingley Bypass and Springvale Road.
The path will create a link between local parks and nearby suburbs of Dingley Village, Waterways and Aspendale Gardens, providing better access to open spaces like Chadwick Reserve in Dingley Village and Braeside Park.
There will also be a well-lit, 6-metre-wide pedestrian underpass at Braeside Park to maintain the important connection to the Woodlands Industrial Estate.
Construction on the project is expected to be complete in late 2021.
The project was previously known as the Mordialloc By-Pass.
