SR 26 - Railroad Bridge Deck Repair

Project news

October 18-Update - The start of construction and the detour on Monday Oct. 15 went smoothly.  It will affect travel via SR 26 to and from Pullman until at least Wednesday Nov. 21.  Travel to Cougar football games on Oct. 20, Nov. 3 and Nov. 17 will be affected but, if all goes as planned, not Thanksgiving or the Apple Cup game on Nov. 22 & 23. 


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 about six weeks, 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 will impact fall semester and Cougar home football game 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.
