Leverett Circle Connector Bridge

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]

Major intersections

The entire route is in Boston, Suffolk County. All exits are unnumbered.

<span class="mw-page-title-main">Big Dig</span> 1991–2007 megaproject in Boston, Massachusetts

The Big Dig was a megaproject in Boston that rerouted the then elevated Central Artery of Interstate 93 that cut across Boston into the O'Neill Tunnel and built the Ted Williams Tunnel to extend Interstate 90 to Logan International Airport. Those two projects were the origin of the official name, the Central Artery/Tunnel Project. Additionally, the project constructed the Zakim Bunker Hill Bridge over the Charles River, created the Rose Kennedy Greenway in the space vacated by the previous I-93 elevated roadway, and funded more than a dozen projects to improve the region's public transportation system. Planning for the project began in 1982; the construction work was carried out between 1991 and 2006; and the project concluded on December 31, 2007. The project's general contractor was Bechtel and Parsons Brinckerhoff was the engineer, who worked as a consortium, both overseen by the Massachusetts Highway Department.

Route 1A is a north–south state highway in Massachusetts, United States. It is an alternate route to U.S. 1 with three signed sections and two unsigned sections where the highway is concurrent with its parent. Due to the reconfiguration of tunnel interchanges brought on by the completion of the Big Dig, Route 1A is discontinuous in the downtown Boston area. Vehicles entering Downtown Boston via the Sumner Tunnel must take I-93 north to the exit for Government Center and make a U-turn to access the entrance ramp to I-93 south and vice versa.

<span class="mw-page-title-main">Callahan Tunnel</span> Tunnel in Boston

The Lieutenant William F. Callahan Jr. Tunnel is one of four tunnels, and one of three road tunnels, beneath Boston Harbor in Boston, Massachusetts. It carries motor vehicles from the North End to Logan International Airport and Route 1A in East Boston. Ordinarily, this tunnel is only used to carry traffic out of the city, and with the completion of the Big Dig it only collects traffic from I-93 southbound and downtown Boston; northbound traffic uses the Ted Williams Tunnel. As of 2016, a toll of $1.50 is charged for non-commercial two-axle vehicles with a Massachusetts E-ZPass, while non-Massachusetts E-ZPass holders are charged $1.75. Vehicles without E-ZPass are charged $2.05 through MassDOT's Pay By Plate MA program. For residents of certain Boston ZIP codes, a discount is in effect using an E-ZPass transponder, costing $0.20.

The Sumner Tunnel is a road tunnel in Boston, Massachusetts, United States. It carries traffic under Boston Harbor in one direction, from Logan International Airport and Route 1A in East Boston. The tunnel originally deposited traffic at the west side of the North End, but with the completion of the Big Dig, it was modified to have two exits. One exit connects to I-93 northbound and downtown Boston near Haymarket Station. The other exit connects to Storrow Drive and Nashua St., connecting Cambridge via Route 28. Traffic headed for I-93 southbound and the Massachusetts Turnpike (I-90) westbound is normally routed to the Ted Williams Tunnel. It is managed by the Massachusetts Department of Transportation.

The tunnel is named for Tip O'Neill, former Speaker of the United States House of Representatives, whose constituency included several of the surrounding communities in Metro Boston.
