SR 26 - Railroad Bridge Deck Repair

Project news

Overview

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 is scheduled to begin in mid-August and will close SR 26 for about six weeks, requiring a detour.  Alternative routes include Eastbound traffic stay ing 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 built to current standards for both commuters and commercial vehicles and protect the high volume tracks for the train traffic below.

Timeline

The project is scheduled to be advertised for private contractor bids on April 23rd with the bid opening coming a month later.  After a technical review, a contract could be expected to be awarded by June.
Construction is currently planned to begin in mid-August with the bridge being operationally complete around the middle of October.

Funding

This (P-2) Highway Capital Structures Preservation project's total funding is $1,378,373 of state and federal dollars.
