SR 26 - Dusty to Colfax - Add Climbing Lanes

Project news

Design on the project began in 2019. Right of way acquisition and design continues. The project is anticipated to go to ad November 15, 2021.

Needs & benefits

The SR 26 corridor is a rural farm to market route and is also heavily utilized by Washington State University students, who travel between the campus in Pullman and Western Washington. Currently, there are no existing climbing (passing) lanes for drivers to use. The addition of truck climbing lanes would address the platooning of vehicles behind slow-moving trucks. There are four climbing lanes proposed with this project - two westbound and two eastbound between the town of Dusty and Colfax.

This project was funded through the Connecting Washington package, passed by the legislature in 2015. 


The project is expected to go to ad in November of 2021 with construction beginning in early 2022. Completion is anticipated for 2023.
