Project Facts
-
This project will add two additional lanes (one general purpose lane in each direction) to I-90 from the Argonne Road Interchange to the Idaho State Line.
- This project Argonne Road to the Idaho State Line is approximately 12-miles in length.
-
Constructing with Portland Cement Concrete Pavement, while having a higher initial cost, provides a cost savings over the extended life of the pavement due to reduced maintenance and repaving needs, plus reduced future pavement repair or rehabilitation requirements.
Summer 2008
• Widening is complete on the
Argonne to Sullivan section. Landscaping is also complete.
• Preliminary Engineering has started on the section from Sullivan Road to the Idaho State Line with a focus on the segment from Sullivan to Barker.
• There is no funding yet appropriated for construction.
Why is WSDOT
pursuing the expansion of I-90?
I-90 is a major commute and travel route for eastern Spokane County and North Idaho with traffic volumes exceeding 100,000 vehicles per day. I-90 is a Strategic Freight Corridor because of the international and domestic interstate and intrastate trade that it carries. Freight traffic through this corridor is expected to increase by 30% over the next 10 years. The freight that is hauled within this corridor has a substantial market value and includes: grain products, household goods, retail merchandise, metal products, groceries, mail, and lumber. If I-90 is not expanded to accommodate growing freight and passenger traffic, congestion and other impacts will substantially reduce the transportation value of this critical corridor.
WSDOT has completed widening of I-90 from Sprague Avenue to Sullivan Road.
Preliminary design work from Sullivan Road to the Idaho State Line is underway with a focus on the Sullivan to Barker segment. Some funding has been acquired for design and purchase of right of way between Sullivan Rd. and Barker Rd. Additional funding, which has not yet been allocated, will be needed in order construct this and future segments.
The End Result
This remaining projects will add two additional lanes (one general purpose lane in each direction) to I-90 from the Sullivan Road Interchange to the Idaho State Line. The project is expected to be built in five major phases: Sullivan Rd. to Barker Rd., Barker Rd Interchange to Harvard Rd. (Liberty Lake), Harvard Rd Interchange, Harvard Rd. to Idaho Road, and the Idaho Road Interchange.
Project Benefits
• The project will improve traffic flow and reduce congestion. There are currently four lanes. There will be six lanes when this project is completed.
What is the project timeline?
• Fall 1989, the "I-90/Four Lakes to Idaho State Line" Environmental Impact Statement was completed. This project is included within the limits of that study.
• The Sprague Avenue to Argonne Road construction project on I-90 was complete late Fall 2001.
• Construction from Argonne Road to Sullivan Road began in 2003 and was completed in 2005.
• Some Preliminary Engineering for the Sullivan to Harvard Road and Harvard Road to the Idaho State Line sections has started with an effort toward final design on the Sullivan to Barker segment complete by Spring of 2009. $10.5 million in federal funding was allocated to this effort.

Environmental Protection
The Environmental Impact Statement (EIS) was completed in 1989. A re-evaluation of environmental impacts for each project within the I-90 corridor is performed as a part of the design process for that project. A new EIS may be needed to complete the projects between Barker Road and the Idaho State Line.
• Sole Source Aquifer protection is enhanced by removal of or retrofitting existing drywells and installation of pretreatment swales prior to infiltration of stormwater.
• Improvements to air quality in the Ambient Air Quality Non-Attainment Area are accomplished by reducing congestion on the mainline.
• Cultural, Historic and Archaeological resources are identified and appropriate mitigation for impacts is implemented
• Noise Abatement is accomplished by the installation of noise walls and/or berms.
• Visual Quality is enhanced by roadside vegetation and aesthetically sensitive finishes on noise walls.
Resolution of issues in each of areas are the result of these supplemental re-evaluations of the impacts each of the I-90 projects.

Increasing safety is one of our priorities
Three sections in this corridor, totaling five miles in length, have been designated as "High Accident Corridor" locations. The majority of crashes in these sections are rear end or sideswipes. The addition of general purpose lanes in each direction will help reduce these types of collisions.
Will this project impact tribal resources?
At WSDOT we seek to address the 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. To learn more about Section 106 Tribal Consultation (also called government-to-government tribal consultation process) please visit WSDOT's Tribal Liaison page, where you'll find the WSDOT Centennial Accord Plan and WSDOT's Tribal Consultation Policy (Adopted by the Transportation Commission on February 19, 2003).
