A rail bridge and elevated train station have been chosen as the design for Hallam Road level crossing’s removal.
According to the State Government, the rail bridge was chosen to minimise disruption to road and rail users, as well as to allow Hallam Road to be widened in the future.
Other designs such as a rail-under-road concept was ruled out due to the high-water table, increased flood risk and impacts to the Hallam Main Drain.
Alternatives would take 12 months longer to build and require compulsory acquisition of businesses, the Government argues.
The rail bridge design also includes improved cycling and pedestrian links.
Transport Infrastructure Minister Jacinta Allan said the project would “get people home sooner and safer in one of the fastest growing communities.
“We’re removing 17 level crossings on the Pakenham line, transforming travel in the south-east.”
About 20,000 vehicles currently use the crossing each day. The boom gates are closed for more than 40 minutes during the two-hour morning peak.
Narre Warren North MP Luke Donnellan said there was a need for better flowing roads “that are fit for purpose”.
He also welcomed “critical upgrades” of Hallam Road, including two new lanes between Ormond Road and South Gippsland Highway, and new traffic lights at the intersection of South Gippsland Highway and Evans Road.
Works on the project are expected to start in 2020, with a 2022 completion date.
