This project will remove the weight restrictions and restore the structural integrity of the Mabton bridges. The team has determined they will need to replace the slough bridge, while the Yakima River Bridge will be retrofitted.
After discussion and review of feedback from the public, the project team will move forward with keeping the improvements to both bridges under one contract. The contractor may close the bridges near Mabton as early as spring 2023.
What to expect
The contractor will first make improvements to the detour route to prepare to move traffic off the bridges. We will not close the bridges until the detour is ready for traffic. The bridges near Mabton will stay closed for the duration of the project and will open once construction is complete. The detour will add about 15 minutes to your drive.
Restoring the Mabton bridges will allow legal loads and make the structures seismic compliant. During construction, traffic will be diverted away from the bridges. Travelers should allow for added travel time.
