The Duportail Bridge Project is officially underway! 

On Wednesday, February 28, 2018, Richland residents, council members, staff and various agency representatives came together to kick off the Duportail Bridge project. Also in attendance were representatives from Apollo, Inc., the awarded contractor tasked with Connecting Richland.

Thank you to everyone who joined us in this celebration! 


December 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.

The temporary in-water work berm, which was utilized in multiple ways for the construction of the bridge, has been completely removed from the Yakima River. Wall 5, also known as the “Sun Wall”, is also completed now aside from minor patching and pigmented sealer application, which will be done in the spring due to temperature requirements. Lastly, landscaping work has also been completed along the two noise walls near Hills Mobile Park.
