The Duportail Bridge is the final segment in the Duportail / Stevens Corridor strategy to provide improved multi-modal connectivity between central Richland and the Queensgate area. This project is split into two phases, the bridge itself, and the intersection of SR240 and Duportail Street. For details on each phase, visit our Project Phases subpage.
