The Woodrow Wilson Bridge is the only Potomac River crossing in the southern half of the Washington, DC region. Designated as both I-495 and I-95, this heavily traveled bridge plays a significant role in the regional transportation system and will be one of the most complex urban transportation improvement projects in the nation. The project involves construction of a twin-bridge, 12-lane, moveable span facility, including major upgrades of four adjacent interchanges and a Deckover joining Rosalie Island to trails in both Maryland and Virginia.
Mahan Rykiel’s design for Rosalie Island features a traditional, Olmsted-inspired park layout with broad expanses of lawn surrounded by large shade and flowering trees. Conceived as a bridge over the bridge, the Deckover flanks the island and provides a direct pedestrian and bicycle connection to Alexandria. The View Garden Deckover commands dramatic views to Washington, DC and Potomac River landmarks. Winding, accessible paths provide a dramatic sequence of spaces leading up to an open park that includes a meadow, wetland interpretation area, and observation pier. Mahan Rykiel was responsible for refining the Design Development plans, developing Construction Documents and planting plans for all areas. Coordination with the four jurisdictions and more than 60 agencies involved with the bridge has been a significant part of the project.
