Works will begin on the Charlton-St Arnaud Road, on the outskirts of Charlton, on December 6.
Detours will be in place while works are carried out to reduce the impacts of flooding.
VicRoads regional rirector, Mal Kersting said the works, being carried out on the behalf of the Buloke Shire, include lowering the existing road and installing larger culverts.
“Once completed, any future flood waters will flow under the road or over the road in extreme weather events, rather than being held back by the road embankments,’’ he said.
“To enable us to carry out the works as quickly as possible, the Charlton-St Arnaud Road (between Back St Arnaud Road and Wright Street) will be closed to through traffic.
“Local traffic will still be able to use the closed road, but under changed traffic conditions.’’
Motorists are advised detours will be in place for the duration of the works. Traffic will be required to travel via Back St Arnaud Road and Wright Street.
Weather permitting, the works are planned to be completed by the end of January 2017. There will be a short break in works during the Christmas/New Year period.
