There will be nightly off-peak hour closures of the Zakim Bridge beginning on the evening of Monday, October 16, according to a notice by MassDot. The closures will be during overnight hours through the morning of Friday, October 21 so crews can conduct standard inspection operations.
The full hours for the closures each night will be from 11:59 p.m., through 5:00 a.m. the following morning. The Zakim Bridge carries traffic on I-93 north and south as well as Route 1 between the North End and Charlestown neighborhoods of Boston.
The detour routes during these times are as follows:
· I-93 northbound: All traffic detoured off I-93 northbound at Exit 26 (Storrow Drive). Travelers seeking to re-access I-93 northbound or Route 1 northbound can utilize the Leverett Circle.
· I-93 southbound: All traffic detoured off I-93 southbound at Exit 28 (Mystic Avenue) in Somerville. Traffic seeking to re-access I-93 southbound will be detoured through Sullivan Square, across the North Washington Street Bridge, and then to the I-93 southbound on-ramp in the Haymarket area.
· Route 1 northbound: Traffic on local roadways in downtown Boston seeking to access Route 1 northbound can utilize the Leverett Circle.
· Route 1 southbound: All traffic will be detoured off Route 1 southbound and into Charlestown. Travelers seeking to re-access Route 1 southbound or I-93 southbound will be directed across the North Washington Street Bridge and to the I-93 south on-ramp in the Haymarket area.
Drivers should seek alternate routes, if possible, to avoid delays. Drivers that must travel through the affected area should expect delays, reduce speed and use caution while traveling along detour route.
