Kerper Boulevard Lane Closures with Traffic Shift

The on-going Kerper Boulevard Sanitary Sewer Reconstruction Project will transition to its next phase requiring the closure of both southbound lanes, with all traffic being shifted into the two northbound lanes, between the HWY 61/151 Entrance Ramp and just north of Fengler Street.

This next phase will start on Monday, March 25, and is anticipated to last approximately eight weeks. Access to driveways and intersections may be altered, but will be maintained during this phase of the project. Motorists are urged to use caution in the area of temporary traffic control. CLICK HERE to view the detour map.
