SR 26 & US 195 Colfax Bridge Replacement – Online Open House

Introduction

The twin bridges on SR 26 and US 195 in Colfax are due for replacement. The Washington State Department of Transportation is seeking feedback on proposed design options for bridge replacement and new intersection alignment for SR 26.

An in person open house will be held on Thursday, December 8, from 4 p.m. to 7 p.m. at the “The Center” in the Whitman County Library.

Colfax, WA 99111

History

The SR 26 bridge (west structure) was constructed in 1938. Parallel to the SR 26 structure is the US 195 bridge (east structure) which was constructed in 1931. Both bridges are classified as structurally deficient, in need of significant repairs and have reached the end of their service life. Federal and state funding has prioritized these two bridges for replacement and intersection improvements.

Design

Several designs are being considered at this time and seeking input and feedback from the public on a preferred design.

Design 1

Replace SR 26 bridge structure then remove the US 195 bridge. Then create a new stop controlled intersection to the north to connect US 195 and SR 26.

Design 2

Replace US 195 bridge with a new structure then remove the SR 26 bridge. Design would also create a southbound US 195 bypass direct to eastbound SR 26 and include a T-intersection, which will be stopped controlled, south of the gas station for all other traffic movements at the US 195 and SR 26 intersection.

Design 3

Replace US 195 bridge with a new structure then remove the SR 26 bridge. This design would then construct a new roundabout option to the north for the intersection of SR 26 and US 195.

Complete streets will also be looked at for the project which includes, alternate forms of transportation such as bike, walk and those who roll.
