SR 26 - Railroad Bridge Deck Repair

Project news


August 7th UPDATE: The date for the bridge repair project and detour will not be scheduled before August 20 to not affect the WSU fall semester move-in traffic. 

This 154 foot long pre-stressed concrete girder bridge 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 will now be scheduled to begin in late-August and will close SR 26 for about six weeks, requiring a detour.  Alternative routes include Eastbound traffic staying on I-90 to just beyond Ritzville and turning south on SR 261 to SR 26.  Westbound traffic on SR 26 from Pullman would turn north at Washtucna onto SR 261 to I-90. 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 both the beginning of fall semester and Cougar home football traffic.  It will also affect commercial trucks involved with the Columbia Basin’s potato harvest.

Needs & Benefits

The immediate need is to replace the bridge deck before it deteriorates further making it unsafe to use.
A new bridge deck will provide a safer facility constructed to meet current standards for both commuters and commercial vehicles on the bridge and protects 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.
Construction is planned for August with the bridge being operationally complete in mid October.
