An Environmental Effects Statement (EES) has been released for the project, and is now open for public feedback.
The project was first floated as an idea in 1954, as an arterial road to connect Brighton and Frankston without needing to use the Nepean Highway.
In today’s proposal, the nine-kilometre-long freeway features noise walls, a new walking and cycling path and twin bridges over the Waterways wetlands.
To protect the natural environment in Braeside Park, special underpasses will be built to allow wildlife to cross between both sides of the freeway and reduce noise and light impacts.
Traffic demand is expected to increase by nearly 10 per cent along the Mornington Peninsula Freeway between 2021 and 2031.
