Created by Swiss architect Christian Menn, the bridge boasts two 270-foot inverted Y-shaped towers made to echo the nearby Bunker Hill Monument. This will be a 10-lane bridge (4+4+2), whose gleaming white cables form two triangles that resemble the billowing sails of a clipper ship. This cable-stayed wonder, which spans the Charles River, will be the widest bridge of its kind in the world when it opens to traffic later this year (2002).
