Town officials are asking drivers to avoid the roundabout at Albany Shaker and Maxwell roads tonight.
Emergency sewer repairs will begin at 7 p.m. and continue until at least 1 a.m. Wednesday.
All traffic will be rerouted to one side of the roundabout during the work, delaying traffic significantly.
The work is needed to repair a main pipe that broke earlier this month. It is the second phase of the repair project.
