The Leverett Circle Connector Bridge is a 1.7 mile-long highway bridge over the Charles River in Boston, Massachusetts, carrying two lanes each of northbound and southbound traffic. It connects to Interstate 93 (I-93) at the northern end (exit 18, formerly 26 from I-93 south) and splits at the southern end, providing direct access to both Storrow Drive and Leverett Circle in Boston. Going northbound, there is also a fork which provides access to the City Square Tunnel under Charlestown to proceed on U.S. Route 1 (US 1) northbound via the Tobin Bridge.

The span was built in conjunction with the more dramatic Leonard P. Zakim Bunker Hill Bridge as part of the Central Artery/Tunnel Project, widely known as the Big Dig. During construction, the Leverett Circle Connector Bridge was sometimes called "Baby Bridge".[2] The bridge opened for traffic on October 7, 1999,[3] at a cost of $22.27 million (equivalent to $38.3 million in 2023[4]).[5]
Also known as the Storrow Drive Connector, it is the largest steel box girder bridge in the United States. It was the winner of a July 2001 National Steel Bridge Alliance (NSBA) "prize bridge" award.[6] Its weaving design[further explanation needed] was determined by the other major structures involved in the Big Dig but unlike other parts of the project, it was finished eight days ahead of schedule.[5]
