The Leverett Circle Connector carries the complex series of loop ramps that link Storrow Drive and Interstate 93 directly with U.S. 1 and the approach to the Tobin Memorial Bridge. The Connector was built as part of the "Big Dig" project which eliminated the old rotary that used to be nearby, hence where the name "Leverett Circle" came from. The Leverett Circle Connector Bridge is directly adjacent to the much larger Zakim Bridge and can appear to be part of the Zakim Bridge if one is not looking closely, but is indeed its own structure.
