Designed by HNTB, the Lenny Zakim Bunker Hill Bridge, over the Charles River, in Boston is an unusual structure.  The 185 ft. width of this bridge makes it the widest of its kind in the world.  The two bridge cable-stayed project is priced at $100 million.  The service load and dynamic forces are complicated by the asymmetric, and unusual cable stay geometry. 

This bridge will be the widest cable-stayed bridge in the world at ten lanes wide.  It is replacing the upper and lower decks of I-93.  With twin spires that echo the Bunker Hill Monument this bridge will be a landmark for Boston.

My husband had the honor or working on this wonderful structure, and our family will always think of him when we pass over the Lenny Zakim Bridge in Boston MA
