Part of the Cobb Highway in south Deniliquin has been closed since Tuesday while roadworks on the highway are undertaken.
The section between Napier St and the roundabout at Hardinge St and Barham Rd will remain closed today and tomorrow while work continues.
Only access from the southern entry of the roundabout is affected.
Edward River Council, which has been contracted to complete the roadworks on behalf of Roads and Maritime Services, said the road closure may be extended should inclement weather impact on the project.
In the meantime it has warned that more traffic, including some heavy vehicles, may take diversions through residential areas of south Deniliquin.
The roadworks include a full width excavation and pavement replacement of the highway, including asphalt overlays.
Works in an area that includes a rail crossing are coordinated with VLine.
