Planned Sewer Construction and Temporary Road Closure
Bumps River Road, Osterville
(HYANNIS, MA – March 9, 2026) Starting Monday, March 16, 2026, the Town of Barnstable’s contractor, Robert B. Our Co. Inc., will begin sewer construction within a portion of Bumps River Road, Osterville as part of the Route 28 West Sewer Expansion Project.
This work marks the first segment of in-road construction in this area. During construction hours, Bumps River Road will be closed from Osterville-West Barnstable Road to Pond Street, as shown in the accompanying figure. Construction will take place Monday through Friday, approximately 7:00 AM to 5:00 PM, weather permitting. Detour signage will be in place and local resident and business access will be maintained. This phase of work is anticipated to be completed by the end of May.
Overall, the Route 28 West Sewer Expansion Project will install approximately six miles of new sewer along Route 28, including portions of Bumps River Road and Osterville–West Barnstable Road, as well as Old East Osterville Road, Oldham Road, Marion Way, and Marquand Drive. This project serves as a backbone for future sewer expansion in Marstons Mills, Osterville, and Cotuit, and is a critical step toward protecting the heavily impaired Three Bays Watershed.
