McKissack provided services to two construction teams, each on a different side of the Potomac River, as they erected a new 12-lane, 7.5-mile drawbridge to allow for 70% fewer bridge openings and traffic interruptions.
The Wilson Bridge is the largest public works project in the Mid-Atlantic. McKissack supported design oversight, construction engineering, inspection services and agency coordination for teams in Alexandria, Virginia, Washington, D.C, and Oxon Hill, Maryland. The new bridge reduces openings to about 65 times per year from nearly 260 openings per year. The Wilson Bridge was sponsored by four cooperating agencies: the Federal Highway Administration, the Virginia Department of Transportation, the Maryland State Highway Administration and the District of Columbia Department of Transportation. The project replaced the old bridge and four adjacent interchanges that are vital to its efficient operation. Office engineering support incorporated document control, invoice verification and information distribution.
