Status

• Design and construction for this safety improvement project is currently unfunded.

• WSDOT continues to look for innovative ways to fund this project.

In the winter months visibility is often very limited due to dense fog. Providing a third lane for slow moving trucks will lessen the risk of collisions in the foggy conditions.

Why is WSDOT improving I-82?
I-82 Southbound from Ellensburg climbs a steep grade (5%), for over four miles, a difficult ascent for most trucks, recreational vehicles, and other heavy moving vehicles.  Other vehicles that can easily negotiate the steep grade are also slowed down as they try to maneuver around the slower vehicles, causing long lines of traffic.

The End Result
Conflicts between slow trucks and faster moving vehicles will be greatly reduced. The third lane will provide additional capacity for this steep grade.

Project Benefits

  • Safety. This truck climbing lane will increase safety by decreasing the conflicts between regular traffic traveling at highway speeds and slow moving truck traffic.

What is the project timeline?
Design and construction for this project is currently unfunded.
