Starting in January 2012, work will begin for the Sioux River South Interceptor Sewer Lining Project located along the west side of the Big Sioux River between 41st Street and 57th Street.

A wastewater bypass pumping system will be placed from 41st Street to 57th Street between the bike trail and the Big Sioux River. The bypass pumping pipe will cross the bike trail at 41st Street, 49th Street, and 57th Street. Pedestrian/bike crossing ramps will be provided at all locations where the bypass pipe crosses the bike trail. Bypass pipe bike trail crossings will be installed the week of January 16, 2012.

Temporary day closures will be announced. Bike trail traffic will be detoured to the east side of the river during closures. Construction personnel may be working adjacent to or crossing the trail during periods when the trail is not closed.

LaQua Logics, Watertown SD, is the prime contractor.
