Overview
Over twelve miles of truck climbing/passing lanes were added to I-90. A 2.2 mile eastbound climbing lane was completed from the Highline Canal to Elk Heights. A ten mile long westbound climbing lane was constructed from Vantage to the top of Ryegrass Summit. Both projects included roadside and safety improvements.
These truck climbing lanes will reduce accidents from conflicts between slower moving vehicles and passing vehicles.
 | Improves Safety
Providing a third lane allows slow-moving trucks and recreational vehicles to safely move out of the 70 mph traffic stream. Ease of travel will be greatly improved.

 | Relieves Congestion
The climbing/passing lanes will allow smoother travel with fewer delays.

Partnerships & Cooperation
WSDOT worked closely with tribal officials to identify and minimize adverse impacts to areas of cultural, archeological or anthropological significance. When applicable, we addressed any concerns of the tribal nations using the process outlined in Section 106 of the National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan. WSDOT consulted with the Yakama Nation and the Wanapum Tribe during the design phase of both truck climbing lane projects.
