A CAPITAL BRIDGE

The new Woodrow Wilson Bridge over the Potomac River, USA is a V-pier concrete design with 82.3m bascule spans with a 21.3m clearance above the shipping channel. Five contracts for the bridge were awarded by the Maryland State Highway Administration. These included dredging, the Virginia Approach, the bascule, and the Maryland Approach. The challenges associated with handling, placing and curing concrete are discussed. Details are given of the mix design, construction of the V-piers from 44.8MPa concrete, tie beams connecting the tips of the V-piers, concrete production and delivery, concrete placing, design of the draw span decks, and the use of thixotropic grout for the post-tensioned structure.
