Charleston Bridge, Boston

The Charlestown bridge in Boston. I have not been to Boston many times. In fact before this year the last time I was drove through Boston was on my way from Canada to New Jersey, in 2002. And I think this bridge was being constructed at the time.

If you browse to the Mass Turnpike Authority's web site, it will tell you that the official name of the bridge is Leonard P. Zakim Bunker Hill Bridge and that it is over the Charles river. It is a cable-stayed Bridge and that it cost $100 million to construct. Its two towers are 270 feet in height. It's unique shape is attributed to Swiss bridge designer Christian Menn, who conceived the bridge to reflect, with its inverted Y-shaped towers, the shape of the Bunker Hill Monument in neighboring Charlestown. The bridges cables -- which suggest a ship in full sail -- also evoke the history of East Boston as a center of shipbuilding.

The MTA site also will tell you 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. The bridge is designed to carry 10 lanes of traffic; eight lanes passing through the legs of the twin towers and two cantilevered on the east side. The bridge is also unique. In addition to being the widest cable-stayed bridge in the world, the bridge is the first "hybrid" cable-stayed bridge in the United States, using both steel and concrete in its frame.
