The Massachusetts Department of Transportation (MassDOT) announced the closure of the Mitchell River Bridge in Chatham. Effective Wednesday, September 17 the bridge will be closed to traffic. Detours for both vehicles and pedestrians will be in place while the bridge is reconstructed.
The current all-wood single leaf bascule bridge was classified as structurally deficient after inspections revealed significant deterioration. The Mitchell River Bridge was also found to be functionally obsolete, according to the project information (Project 603690).
A new single-leaf moveable bascule bridge (drawbridge) with a timber superstructure and a concrete and steel foundation will replace the old bridge, according to MassDOT. The work will be done by SPS New England to the tune of $15,000,000+.
While the bridge is closed, detours will be in place. Motorist will be detoured via Stage Harbor Road north to the rotary and east and south onto Main Street (see MassDOT map below).
While the work is done, the channel will remain open to mariners. Brief closures will occur during the project, specifically when the old decking is removed.
Officials expect the bridge to remain closed to motorists until the project is completed in mid-June 2016.
