Harbor Road is closed at Main Street due to the collapse of the Mill Pond dam, which washed away the roadway.
To detour around the road closure:
Riding east on Harbor, make a right onto Rhododendron Drive, at the fork make either a left on Saddle Road (shorter), or a right on Rhododendron (longer). Either way will lead to Main Street just south of the pond.
On Main Street, ride south past the pond, make a right onto Saddle Road, just before the light. At the Upper Mill Pond fork go either left onto Rhododendron Drive (longer), or a right to stay on Saddle (shorter). From Saddle, take a right onto Rhododendron, from Rhododendron, make a left to stay on Rhododendron. Make a left to continue onto Harbor.
