​Construction Activities Update

Work at the intersection of State Street and Stevens Street has been completed. The intersection is back open to traffic. Bus route 68 will resume regular routes and stop locations. Final work at the George Street site is in process. Crews are on schedule to have the project completed in late August.

Project Description

MCES is cleaning a regional sanitary sewer interceptor located on the west side of St. Paul, from March 2019 through August 2019.  The regional sanitary sewer interceptor consists of a 3-ft wide by 8-ft tall sandstone tunnel that is partially lined with clay tile.  The upper portion of the tunnels are exposed sandstone. Recent inspections of the sandstone tunnel indicated that debris removal is needed to maintain sewer operations and improved access is needed for debris removal and future maintenance activities.

A new maintenance hole will be installed on George Street between Livingston Avenue and Robert Street.  The new maintenance hole is necessary to safely access a section of the tunnel.  The work requires digging a 60-80-foot shaft and installing a maintenance hole at street level.  George Street will remain open to traffic; however, a portion of on-street parking will be closed, and crews and equipment will be in a fenced work site for the duration of the project.  

At the intersection of State Street and Stevens Street, additional ground-level work is needed that will require a temporary road closure.
