I-90 - Eastgate to SR 900 Peak Use Shoulder Lanes

Status

May 2017

We continue to meet with our Stakeholder Advisory Group, comprised of local jurisdictions and stakeholders, to review design options and traffic analysis.


Materials from the October 2016 and January 2017 meetings are available in our project library.

Why is WSDOT building this project?
As population grows in the Puget Sound region, so does traffic congestion. In an effort to ease congestion along this heavily traveled portion of I-90, WSDOT is creating peak use shoulder lanes from Eastgate to SR 900. These shoulders will add additional capacity during the morning and afternoon commutes.

The End Result
The project will reconstruct shoulders along both directions of I-90 from Eastgate to Issaquah to serve as additional lanes during the morning and afternoon commutes. New overhead electronic signs will let drivers know if the peak use shoulder lanes are open and closed. In addition, the project may retrofit and construct new noise barriers in some places along the improved route.

The eastbound I-90 peak use shoulder lane is proposed between the Eastgate Interchange and West Lake Sammamish Parkway. The westbound peak use shoulder lane is proposed between SR 900 and the 150th Ave SE exit.

Drivers may use the peak use shoulder lanes during the following times:
Eastbound I-90: 3 p.m. to 7 p.m.
Westbound I-90: 6 a.m. to 9 a.m.

With the exception of buses, vehicles over 10,000 gross vehicle weight will be prohibited from using the lane.

Project Benefits
By building more capacity to handle large volumes of traffic on I-90, we expect to improve congestion for travelers.
