The Leonard P. Zakim Bunker Hill Memorial Bridge will be closed overnight next week for inspection, state officials announced Friday.
The 10-lane bridge will close at midnight Monday, reopening at 5 a.m. Tuesday, and will be closed for the same hours the next three nights.
The closure will clear the way for a “routine inspection” that happens approximately every two years, according to Patrick Marvin, a Massachusetts Department of Transportation spokesman.
Two cranes will be used to lift crews to review the towers and cables that have made the bridge an icon over the last two decades.
The bridge last closed for similar inspection work in the spring of 2015.
Drivers heading north on Route 93 will be detoured at Exit 26 in the Thomas P. O’Neill Tunnel toward Storrow Drive, where they can use the Leverett Connector to meet back with the highway. Drivers in Boston looking to access Route 1 northbound will also use the Leverett Connector.
Drivers headed south toward the city on Route 93 or Route 1 will be detoured through Charlestown and across the North Washington Street Bridge before returning to the highway in downtown Boston.Adam Vaccaro can be reached at firstname.lastname@example.org. Follow him on Twitter at @adamtvaccaro.
