General Schedule Information
The City began construction in March 2018 and anticipates opening the bridge to traffic in the summer of 2020. The construction process is arranged around limited opportunities to do construction work in the Yakima River. The limitations are imposed for fish passage reasons by federal agencies.
Duportail Bridge Groundbreaking Event
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!
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.
