Project Information

Duportail Bridge Dwg

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 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.

November 1, 2019 Update:

The Duportail Bridge project is progressing as anticipated. Concrete for all five bridge deck spans has been poured and cured now. The contractor, Apollo, Inc., is continuing the ongoing efforts of installing three 24” ductile iron water mains that are attached underneath the bridge via utility hangers. Similarly, the contractor is also working on installing conduit runs under the bridge for dry utilities such as power and communications. Contractor will also be working on the traffic barrier and rest area on the bridge in the upcoming month of November.

Wall 5, also known as the “Sun Wall”, is also completed now aside from minor patching and pigmented sealer application, which will likely be done in the spring due to temperature requirements. Landscaping work has also been completed along the two noise walls near Hills Mobile Park. Lastly, the temporary in-water work berm is going to be removed by the Contractor in November.
