The Massachusetts Department of Transportation has announced that a weekend road closure and detour of a portion of the Middlesex Turnpike in the vicinity of the Shawsheen River crossing in Bedford will be implemented from Friday, June 14, at  7 p.m. until Sunday, June 16 at 7 p.m.

The road will be closed so crews can begin excavation and staging needed for rebuilding the bridge.

For these operations, southbound Middlesex Turnpike traffic will be detoured at Lexington Road to Old Billerica Road southbound to Route 62 eastbound to Middlesex Turnpike.

Northbound Middlesex Turnpike traffic will be detoured at Crosby Drive to Route 62 westbound to Old Billerica Road northbound to Lexington Road northbound to Middlesex Turnpike. Those traveling through the area should expect delays, reduce speed and use caution.

The schedule for this work is weather-dependent and subject to change without notice.

This work is part of a $35 million transportation improvement project in Bedford and Billerica, and is currently scheduled to be completed in 2023.
