- We are currently reviewing the draft report with WSDOT HQ and expect to release the final report by summer of 2012.
What is the I-90 corridor study?
The I-90 corridor study is a planning process used to gather information to determine if improvements are needed to meet existing and future transportation needs. The process includes gathering input from local officials and the public; collecting and analyzing traffic and other data; reviewing existing local plans and their affect on transportation; projecting future travel demand; and evaluating improvement options.
Why is WSDOT
studying I-90 between Bellevue and North Bend?
WSDOT and the Federal Highway Administration (FHWA) co-manage the interstate system in Washington State. Any changes to the interstate system, including I-90, require FHWA’s approval.
FHWA approved construction of the I-90 Sunset interchange in Issaquah with the requirement that WSDOT fund and conduct a corridor study that addresses the safety and mobility needs of this fast-growing corridor.
To meet this requirement, the 2005 Washington State legislature funded $2 million for a study of I-90 between Eastgate in Bellevue and 465th Ave. S.E. in North Bend so that we can identify short- and long-term projects for this corridor to address safety and mobility needs.
As we develop a list of near and long-term investments for I-90, between Bellevue and North Bend, we will take into consideration the relationship of all the plans and projects (regional, state and federal) for the interstate.
The End Result
The corridor report for I-90 will provide WSDOT and communities along the corridor with a list of safety and mobility improvements that could be implemented over the next 20 years if funding becomes available.
Project Benefits
The corridor study will provide a list of safety, congestion relief, and preservation improvements that support the safe and efficient travel or people and goods on I-90. This list of projects may then be incorporated into the Puget Sound Regional Council’s Transportation Plan (Destination 2030) and the Washington Transportation Plan.
What is the project timeline?
We began this study by collecting travel related data for the interstate and gathering comments from local communities. We've reviewed this information and developed improvement options for I-90. In spring 2011, we expect to complete the corridor plan and make the final list of improvement options available on the WSDOT Website and at community locations.
