Leonard P. Zakim Bunker Hill Bridge

With its graceful lines and 270-foot towers, the Leonard P. Zakim Bunker Hill Bridge fuses Boston's future with its historic past. Swiss bridge designer Christian Menn conceived the bridge to reflect, with its inverted Y-shaped towers, the shape of the Bunker Hill Monument in neighboring Charlestown. In addition to the Battle of Bunker Hill, the bridge is also dedicated to the life of civil rights activist Lenny Zakim. It serves as a permanent memorial to a man who bridged many gaps. The bridges cables -- which suggest a ship in full sail -- also evoke the history of East Boston as a center of shipbuilding.

The bridge, at 1,432 feet long, emerges from the underground Central Artery near the Fleet Center at Causeway Street, crossing the river to make connections with both I-93 and Route 1.
