The interchange, just south of Maryborough, will deliver improved safety and operational efficiency to help support future growth for the area.
“The interchange has a poor safety record and while interim measures such as a reduced speed limit and signage upgrades have resulted in a reduction in crashes, this project will provide a long-term solution,” Federal Minister for Infrastructure and Transport Darren Chester said in a statement.
The project involves the construction of a new northbound off-ramp and overpass structure, which will require motorists to exit to the left instead of the right.
Both through lines of highway traffic will travel under the new overpass and will be separated by a wide centre line treatment.
The upgrade is expected to reduce the number and severity of crashes, reduce maintenance costs and vehicle operating costs. The speed limit, as a result, will be able to be increased.
The project is on track to begin in mid-2016 and completed in mid-2017.
