SR 26 - Railroad Bridge Deck Repair

Project news

December 7th  Update   

The closure and detour will end at noon Friday December 14.  By then the newly poured concrete bridge rails will be cured and final work including curbing, guardrail, deck grooving and temporary pavement striping will be complete. The project began Oct. 15 and WSDOT & Degerstrom tried unsuccessfully to accelerate the project to open SR 26 by Nov. 21 for Thanksgiving and the Apple Cup fans which proved impossible due to permitting and weather.

The closure barricades will remain in place until Friday, but WSDOT is grateful for the support and understanding from parents and students and their patience over these past eight weeks.  We are also grateful for the difficult work accomplished under wintery conditions by our contractor, N.A. Degerstrom and BNSF.

Overview

This 154 foot long pre-stressed concrete girder bridge constructed in 1957 in southern Adams County had a bridge deck that was deteriorating at a rapid rate requiring continuous maintenance. Its already scheduled replacement next spring was advanced from 2019 to this fall as our Bridge office technicians recommended against allowing the structure to endure another winter.  The bridge deck replacement began Oct. 15 and was expected to close SR 26 for six weeks, requiring the detour.   

SR 26 is a primary route from western Washington to Washington State University in Pullman. The average traffic count is just under 2,000 vehicles a day, but that number can double on WSU event weekends. This closure impacts Cougar home football game, special event and holiday traffic. Detour alternative routes include Eastbound traffic staying on I-90 to just beyond Ritzville and turning south on SR 261 down to SR 26.  Westbound traffic on SR 26 from Pullman would turn north at Washtucna onto SR 261 up to I-90.

Needs & Benefits

The immediate need is to replace the bridge deck before it deteriorates further making it unsafe to use the bridge at all.  A new bridge deck constructed to current standards will provide a safer structure for both commuters and commercial vehicles on the bridge and protect the high volume tracks for the train traffic below.
