Project Facts
- This will be Snohomish County's fifth direct access facility.
- The project team estimates these improvements will increase bus passenger trips by about 1,000 per day in 2030.
- Community Transit will build a 690-stall garage at the Mountlake Terrace Park and Ride, which will complement the freeway station project.
October 2008
- Engineers are finalizing the designs for the project. We expect to advertise the project for competitive bidding in December and begin construction in spring 2009.
- Community Transit closed the Mountlake Terrace Park and Ride in Dec. 2007 for construction of a new parking garage. The garage project is separate from Sound Transit and WSDOT's freeway station project. For details, please visit Community Transit's Web site.

Overview
WSDOT and Sound Transit will build a bus station in the median of I-5 at 236th Street SW in Mountlake Terrace. The station will have bus-only ramp connections to the I-5 HOV lanes. An overhead, covered pedestrian bridge will connect the station to the Mountlake Terrace Park and Ride. We will also bring the 236th Street and 228th Street bridges up to current earthquake-resistance standards.
Why is WSDOT
working with Sound Transit to build a freeway station on I-5 in Mountlake Terrace?
Sound Transit buses do not currently serve the Mountlake Terrace Park and Ride because they would have to merge across three lanes of traffic from the I-5 HOV lanes to the 220th Street SW exit and then onto city streets to access the lot. This circuitous route would cause service delays, increase bus operating costs, and increase the potential for collisions on I-5 from buses weaving between the HOV lanes and on and off-ramps.
The End Result
The freeway station in the I-5 median will provide Sound Transit buses efficient access to the Mountlake Terrace Park and Ride without having to merge across freeway lanes or travel on city streets.
Project Benefits
Fast and reliable transit service. Buses will be able to load and unload riders without merging across the freeway and driving through city streets to reach the park and ride.
Safety. Providing bus access in the median eliminates the risk of collisions from buses weaving between the HOV lanes and on- and off-ramps. We are also increasing the earthquake resistance of the 236th Street bridge.
Freeway efficiency. Transit facilities such as this help move more people in fewer vehicles.
What is the project timeline?

Late 2010 - Project complete
Public Involvement
Your thoughts and opinions are important to us. Please revisit this page for continuing project status.
Sound Transit hosted an open house in 2004 to provide information and receive comments from the public on this project.
If you would like to be included on Sound Transit's mailing list for project updates, e-mail Sound Transit at mailinglist@soundtransit.org.
Environmental Protection
There are wetlands and streams on the outsides of I-5 south of the project area. We will protect these environmental features during construction with erosion and sediment control measures.

Services Web site for more information.
Increasing safety is one of our priorities
During the design process, we added an element to this project to increase earthquake resistance on the 228th and 236th Street bridges. This work is unrelated to the freeway station work, except that we must do it before or concurrently with the freeway station construction so that we do not have to affect the freeway station in the future with this seismic retrofit work.
In summer 2007 we did an earthquake resistance study on the 228th and 236th Street bridges. Our bridge specialists determined that the 228th Street bridge meets current earthquake resistance standards, so we will not have to do any seismic work on that bridge. They also determined that the 236th Street SW bridge will not need as much earthquake resistance work as we had originally anticipated. As a result, approximately $1.5 million of the original amount that we budgeted for the work will be used for other projects in our seismic retrofit program.
We are also increasing safety by eliminating the risk of collisions from buses weaving between the HOV lanes and on- and off-ramps.
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 the tribal consultation process please visit WSDOT's Tribal Liaison page, where you'll find links to WSDOT Centennial Accord Plan and WSDOT's Tribal Consultation Policy.
This project was determined to be exempt from Section 106 review per the Programmatic Agreement between Washington State Department of Transportation, the Federal Highway Administration, the Advisory Council on Historic Preservation, and the State Historic Preservation Officer signed July 18, 2000.
