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 summer of 2020.
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.

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.
October 2018 Update:
The Duportail Bridge project reached an important milestone at the end of September. The Duportail Bridge in-water work window came to a close on September 30 with the City’s contractor successfully completing the critical work required in that period. Concrete columns at piers 3, 4, and 5 have all been poured now. Concrete cross beams on top of the columns at pier 3 and 5 have also been poured, with pier 4 beams scheduled to be done in the next few weeks.
With the in-water work period closed, Apollo’s work will shift to other parts of the project not effected by the permitting limitations involving the Yakima River. Between now and next spring, little to no work will occur on the completed columns while the contractor shifts focus to the south side of the river to construct foundations in that area. Work in the area of the completed columns will resume next spring. As part of a plan to accelerate the project schedule, Apollo has modified the work berm in the river to support use of a larger crane to set the pre-cast concrete girders than was planned by the project’s engineering team. The plan, reviewed and approved by the project’s environmental regulators and the City, will result in the modified work berm remaining in the river over the winter and spring. The large crane is expected to be mobilized on site next spring after the south side foundations are completed and the project is ready to install the pre-cast girders.
On the southwest side of the project, progress on the noise walls has been substantial, especially on the segment of the wall south of the Hills Mobile Home Park driveway. This work will continue in the coming months.
