A signature project of Boston’s multi-billion dollar Central Artery/Tunnel, the Leonard P. Zakim Bunker Hill Bridge spanning the Charles River was completed in 2002 and opened to traffic in March 2003.

The $100 million, 10-lane asymmetrical cable-stayed bridge has been recognized as a monumental achievement in American bridge engineering and construction. It is the first asymmetrical cable-stayed bridge in the United States and the widest cable-stayed bridge in the world. Kiewit Construction Company, a subsidiary of Kiewit Corporation, led the joint venture that began construction on the 183-ft.-wide structure in September 1997.

The bridge’s main elements are the two inverted Y-shaped hollow-core concrete towers located on opposite sides of the Charles River. Kiewit used a cast-in-place construction method for the towers as a part of a value-engineering proposal. The south tower reaches a height of 295 ft., while the north tower extends 323-ft. high. These structures support the 745-ft. steel center span. Eight lanes of I-93 traffic pass between the legs of the towers, and two lanes of local traffic are cantilevered off to the bridge’s east side.

Longfellow (originally, the Cambridge) Bridge is one of the most architecturally distinguished bridges in Massachusetts. Located on the site of the 1793 West Boston Bridge, this graceful steel and granite structure was completed in 1908, and renamed to honor Henry Wadsworth Longfellow in 1927. The bridge joins Cambridge Street in Boston with Main Street in Cambridge and carries the Massachusetts Bay Transportation Authority (MBTA) Red Line and two-way vehicular traffic across the Charles River. The bridge presently carries 28,000 motor vehicles, 90,000 transit users, and significant numbers of pedestrians and bicyclists each day.

The Tobin Memorial Bridge was erected in 1948-49 and opened to traffic in 1950. It connects the Charlestown section of Boston with Chelsea. The bridge provides three travel lanes northbound on its lower level and three lanes southbound on the upper level. The 36-foot-wide roadway is bounded on both sides by safety walks (2’7″ wide) with steel-pipe railings on each side.

The main structure over the Mystic River is a three-span, cantilevered truss 1,525′ in length. Its center span is 800′ and the maximum truss height is 115′. It provides a navigable waterway opening 700′ wide by 135′ high. A smaller, simply supported warren truss spans the Little Mystic. It reaches a maximum truss height of 65′ and is 439′ long. Its navigable waterway opening measures 340′ wide by 100′ high.
