Projected work window
Harwich’s Route 28 project update schedules installation of a new 12-inch water main for November 16–20, 2026, with through traffic diverted onto Lower County Road. The published plan keeps access for residents, businesses, school transportation and emergency vehicles within the work area.
Check the approach before travelling
The town’s summary and its attached contractor schedule give different work segments and detour endpoints for that week. Neither should be treated as a confirmed turn-by-turn route. Follow posted signs and onsite traffic officers, and allow extra travel time.
The schedule is projected: progress, weather, materials and permitting can change the work. Recheck the town’s update before travelling.
