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! 


November 2018 Update:

During the months of October and November, the focus on the Duportail Bridge construction has shifted from the north side of the Yakima River to the south side. Apollo has begun installation of the 42” ductile iron water main along City View Drive and has installed the majority of the storm piping and infiltration trenches. Also, demolition of a portion of the CID canal has begun as irrigation season has come to an end. Prior to irrigation turning on early next spring, the contractor will replace this portion with a rectangular concrete canal, along with completing Wall 5 (“Sun Wall”) and Pier 2 columns and concrete beam. 

The in-water work berm has been modified, built up in elevation and armored to account for high water flows, and it will now remain in place until it is needed next spring for the large Lampson Transi-Lift crane for the setting of the concrete girders across all 5 spans.

All of the concrete for noise wall 1 (south of the Hills Mobile Home Park driveway) has been poured with only minor patching and colored sealer remaining to be completed. Apollo is continuing to make progress on noise wall 2 (north of the Hills Mobile Home Park driveway.
