As part of the Lathams Road Upgrade, we’ll:

  • upgrade the intersection at Frankston-Dandenong Road
  • provide a right turn lane at Levida, Titan, Brett and Tova Drive
  • widen the existing roundabouts at Oliphant Way and Frankston Gardens Drive
  • install new traffic lights at the Stephensons Road and Colemans Road intersections
  • build a new bridge over the Peninsula Link, adding a new lane in each direction over the freeway
  • build new shared walking and cycling paths
  • install safety barriers along the road.


This upgrade will:

  • improve traffic flow and travel times
  • enhance connectivity for the local community and businesses in Carrum Downs and Seaford
  • make it easier and safer for you to walk or cycle around your local area
  • lower the risk and severity of crashes by adding safety barriers.
