WORK has begun on an $8 million upgrade of the Frankston-Dandenong Rd, Wedge Rd and Boundary Rd intersection in Carrum Downs.
More approach lanes on Boundary Rd and Wedge Rd will be added and traffic lights will be installed at the intersection.
The new traffic lights will mean drivers no longer will have to wait for gaps in oncoming traffic when turning from the side roads onto Frankston-Dandenong Rd.
Major pre-construction works have been done over several months to relocate underground services at the intersection including power,
lighting and telecommunications.
Carrum Labor MP Sonya Kilkenny said residents had long called for the upgrade and the Labor state government was keeping its promise to upgrade the intersection.
In the five years to December 2013, there were 17 crashes at the intersection, with seven of them resulting in serious injury.
While road works are carried out, access will be maintained through the intersection with reduced speed limits in place.
The intersection upgrade is due to be complete by mid-2016.
