An emergency water repair has forced the closure of Lincolnway West between Bendix Drive and Ardmore Trail.
The road was closed as of 7 pm on Monday, and the repairs could take anywhere from three to five days to complete.
The purpose of the closure is to fix a leak in a water main service pipe.
South Bend Water Works will conduct the repairs overnight. There is a possibility that one lane in each direction could be opened by Tuesday morning.
However, drivers are encouraged to avoid this stretch of road if possible on Tuesday.
