SR 26 - Railroad Bridge Deck Repair

Project news

November 7 Update   

The closure and detour will now extend beyond the Nov. 21 target date for reopening. Work began Oct. 15 and the contract’s 45-day closure was scheduled to end on Nov. 28. WSDOT & Degerstrom were trying to accelerate the project to open SR 26 by Nov. 21 for Thanksgiving and the Apple Cup fans.  The remaining work may now require the closure to extend into December.  

The closure barricades will remain in place. The simple 32-mile detour around the closure uses state routes 17, 260, and US 395 and adds an extra 14 miles to the trip compared to the usual 17.5 mile drive through the now-closed portion of SR 26.


This 154 foot long pre-stressed concrete girder bridge constructed in 1957 in southern Adams County has a bridge deck that is deteriorating at a rapid rate requiring continuous maintenance.  Its planned replacement has been advanced from 2019 to this fall as our Bridge office technicians recommended against allowing the structure to endure another winter.  The bridge deck replacement begins Oct. 15 and will close SR 26 for six weeks or more, requiring a 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.  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.


The project was advertised for private contractor bids on April 23, 2018. Contract #9275 was awarded on May 29 to N.A. Degerstrom, Inc. for $1,086,510.00.
