The state government announced on Sunday that level crossings at Swanpool Avenue and Chelsea Road in Chelsea,and Lochiel Avenue in Edithvale,will be gone by the end of 2022.
It had previously made an election promise to remove them by 2025.
Those roads will be closed permanently where they cross the Frankston line,in a decision the state government says will tackle excessive and dangerous rat-running on local streets.
Their removal will occur in tandem with the previously announced removal of a number of other crossings on the line,including at Edithvale and Bondi roads.
The rail line will be lowered into a trench along this section of the line,unlike in neighbouring Carrum and at Skye Road in Frankston where it has been controversially elevated.
All up,the government is spending $3 billion to remove 18 level crossings on the Frankston line,including demolishing and rebuilding 12 railway stations.
