The Northeast 120th Street Extension Project is a new 880-foot extension of an existing street in a heavily urbanized area marked by car dealerships, a local college and more than 200 small and medium-sized businesses. It is at the heart of Totem Lake, a booming, busy business district. Existing signalized intersections were so heavily used, typical wait times exceeded 83 seconds.
The five goals of the project included access, mobility, capacity, congestion, and bicycle safety. The project improved access for all modes of transportation with ADA compliant curbs, a planted strip that serves as a buffer between pedestrians and vehicles, and bike lanes and sidewalks on both sides of the street.
Additionally, the bus access delivers improvements today and the infrastructure for future improvements in the form of a connection hub for buses. Intelligent Transportation Systems embedded in traffic signal systems at 124th Avenue Northeast, Northeast 120th Street and Slater Avenue streamline signal operations. In 2035, drivers will still wait less at intersections than they did in 2013.
