Concord is leading a multidisciplinary team in the design of corridor-wide traffic signal upgrades to improve traffic operations on two major city corridors that provide access to downtown Seattle. 1st Avenue is a key industrial corridor within the SODO area of Seattle that connects large distribution centers to regional freight routes at the Spokane Viaduct and East Marginal Way. Denny Way is a highly urbanized corridor at the nexus of the angled downtown street grid and the north/south street grid of the rapidly re-developing South Lake Union neighborhood. Denny Way connects some of the city's most dense population centers from the Capital Hill neighborhood to the waterfront, while providing access to key regional routes of Aurora Avenue and I-5. By improving traffic operations, this project will promote the economic vitality of Seattle's commercial centers and improve pedestrian safety and accessibility.
