KITTITAS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS <br />STUDY SESSION STAFF REPORT <br />STUDY SESSION DATE: February 28, 2022 <br />TOPIC: North Thorp Highway -Yakima River Bridge CRP 302-20 <br />ACTION REQUESTED: Informational Only <br />LEAD STAFF: <br />Mark R. Cook <br />RECOMMENDATION: <br />Informational briefing — no action required by the Board. <br />BRIEFING SUMMARY: <br />• On December 30, 2019, Washington State Department of Transportation (WSDOT) <br />notified Public Works of selection of the North Thorp Highway -Yakima River Bridge <br />selection to receive funding for repairs. <br />• Design work and environmental permitting is nearing completion. <br />• Anticipate construction summer 2022. <br />• Work requires closure of the bridge. <br />• Public Works proposes to host an informational meeting for the residents and adjacent <br />property owners. <br />BACKGROUND: <br />The North Thorp Highway -Yakima River Bridge requires preventive maintenance to extend the <br />life of the structure. This steel truss structure, constructed in 1936 has two lanes for traffic. The <br />existing paint system has failed throughout much of the bridge truss. This project will rehabilitate <br />the bridge by removing the existing paint system and repainting, repairing bottom chord panel <br />points, joints, and repair damaged truss portal members. Federal Funding has been secured <br />through WSDOT Local Bridge Program for the needed construction work on the bridge. <br />Construction is planned for this summer. <br />DISCUSSION: <br />Paint systems are replaced under warm weather conditions. To protect the surrounding <br />environment the bridge will be encapsulated while removing the existing paint and applying new <br />paint. The roadway width across the bridge is not sufficient to safely carry traffic and provide for <br />the painting to occur at the same time. Public Works proposes to host an informational meeting <br />for stakeholders including, property owners and emergency services, to share about the project <br />and provide updated project information. This informational meeting will be held March 30, <br />2022, at 2:00 p.m. at the conference room in the Upper County Shop. <br />FISCAL IMPACTS: <br />None are identified at this time. <br />ATTACHMENTS: <br />None <br />Page 1 of 1 <br />Public Works "Work Session Staff Report" 2022 <br />
