Final Bridge Type - East End Bridge
Median-Tower Cable-Stayed Center Cables
The Median-Tower Cable-Stayed Center Cables Bridge Type features two needle towers with cables running from the towers to the median of the bridge deck. The design provides motorists, pedestrians and cyclists with unobstructed views of the surrounding landscape looking outward from the bridge deck and provides the surrounding area with a visually transparent structure to blend with the area.
The bridge type is a low maintenance bridge type that meets all engineering, navigation and safety criteria. Two concrete needle towers rise 300 feet above the water and support the superstructure with steel and concrete box girders and concrete deck. The sheathed steel strand cables extend from the tower to the bridge deck median in a fan formation.
The navigation channel for river traffic meets U.S. Coast Guard requirements with a single, 900-foot wide waterway in the center span of the bridge.

The Three-Tower Cable-Stayed Bridge Type was selected after a thorough public involvement process that included feedback from advisory teams as well as the general public during the development of guidelines, concepts, alternatives and ultimately the final bridge type.
