In a cable-stayed bridge, instead of hanging the roadbed from cables slung over towers, the cables run directly between the roadbed and the towers. Although cable-stayed bridges have become common in Europe since World War II, they are relatively new to North America.
The bridge, designed by Swiss civil engineer Christian Menn , follows a new design in which two outer lanes are cantilevered outside the towers while another eight lanes run through the towers. It has a striking, graceful appearance that is meant to echo the Bunker Hill Monument with its' towers and the USS Constitution with its' white cables.
The bridge is within view of the Bunker Hill Monument. Its name commemorates both the battle and Boston civic leader Leonard P. Zakim, whose theme was "building bridges between peoples".
