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.
The City began construction in March 2018 and anticipates opening the bridge to traffic in the fall of 2020.
This project is split into two phases, the bridge itself, and the intersection of SR240 and Duportail Street.

For the duration of the project's construction, access to the river at the project site is restricted. This includes the boat launch and trail system. Please use alternate boat launches upstream and downstream from the project site. A detour to the trail route is in place and is signed accordingly.
June 2020 Update:
The Duportail Bridge Project is progressing as anticipated and is still on track for completion this fall. With the bridge deck, approach slabs and bridge barrier completed, the Contractor is now finishing bridge sidewalk work. Water, electrical and communications conduits have all been installed underneath the bridge and are live across the Yakima River. With the new water main connections made to the City’s reservoirs, the old section of concrete pipe has now been abandoned. Roadway connections at both ends of the bridge and Tanglewood Drive have been paved with asphalt. Contractor has planted and seeded part of the mitigation site area and will complete the rest after completion of the gravel parking lot. Permanent striping and signing, pigmented concrete sealer application, and bridge railing are some of the upcoming work items.
Phase 2 of the project, which includes improvements to the SR240 intersection, the at-grade railroad crossing, and street improvements that end near Cottonwood drive, will begin on June 15. Some of the early tasks will include building an access road from Laborers Union Building/Mosaic Apartments area to Tanglewood Drive and boring under SR 240 for both 24” ductile iron water main connection and electrical/communication lines.
