Zakim Bunker Hill Memorial Bridge

Owner: Massachusetts Turnpike Authority
Designer: Christian Menn
Contractor: Bechtel/Parsons Brinkerhoff

With its graceful lines and 270-foot towers, the Leonard P. Zakim Bunker Hill Bridge fuses Boston's future with its historic past. It is the widest cable-stayed bridge in the world and the first "hybrid" cable-stayed bridge in the United States, using both steel and concrete in its frame. Swiss bridge designer Christian Menn conceived the bridge, with its inverted Y-shaped towers, to reflect the shape of the Bunker Hill Monument in neighboring Charlestown.
