Abstract:
The Woodrow Wilson Memorial Bridge carries traffic on both I-95, the primary north-south corridor on the east coast, and I-495, the Capital beltway. In order to increase capacity and replace the rapidly deteriorating existing structure, a new bridge is currently under construction. A unique system of V-shaped piers and haunched steel girders are utilized to aesthetically provide an arch shaped appearance. The bridge foundations, V-piers, bascule piers, abutments and deck slab will be constructed using high performance concrete. A discussion of the various admixtures used in the concrete mix to provide a durable concrete that minimizes cracking and chloride intrusion into the concrete will be presented.
