Bridge Design at the U.S. Naval Academy for the Replacement of McNair Road Bridge
The replacement of the 234-foot McNair Road Bridge at the U.S. Naval Academy was a fast-tracked and challenging project in the design-build format. The six-span continuous bridge is located in Annapolis, MD, at the mouth of the environmentally sensitive Chesapeake Bay. Tight design and construction tolerances were required to tie the bridge into pile supported approaches at both ends and a pile supported library along the length. The bridge was made up of prestressed concrete beams with a reinforced concrete façade beam, and an expedited schedule was required to complete the work prior to the start of the fall semester. Because of the short construction period available, Accelerated Bridge Construction (ABC) Technologies were used, including precast pilecaps.
