City of Muskegon issued the following announcement on Aug. 11.
Southbound Shoreline Drive (US-31 BR) will be closed near the split to Webster Avenue starting on Monday, August 17th. The closure is required for the installation of a new sewer main under the street and is expected to last approximately 2 weeks. Southbound US-31 BR traffic will be detoured onto Webster Avenue and then onto Terrace before rejoining Shoreline Drive. Upon completion of the Southbound Closure a similar closure will be required on northbound Shoreline Drive (US-31 BR) that will utilize the same detour.
This work is being completed by Jackson-Merkey Contractors and is part of an ~$3M sewer upgrade project in the area of Spring and Yuba Streets that will be ongoing throughout the rest of the year.
