SR 167 Master Plan – What we know so far

What has WSDOT studied so far?

WSDOT spent time working to understand the existing condition and future conditions of the SR 167 corridor.

Community Engagement

WSDOT conducted listening sessions with community-based organizations. The organizations provided preliminary insights into vulnerable and overburdened communities within the SR 167 study area. Equity priorities discussed in the listening sessions included the need for services to get from homes to public transit, for more transit routes throughout the corridor, particularly east-west routes, and the need for better transit access to job centers. Other feedback included the impact of traffic congestion on moving people and goods (freight trucks) around the region and the limited number of active transportation options (sidewalks, bike lanes, and trails).

This summer WSDOT will conduct a series of workshops with equity priority communities. The workshops will be used to develop and understand the benefits of various transportation solutions, and to identify the solutions that best meet the needs of the equity priority communities.

Community Profile

WSDOT developed a Community Profile that shows vulnerable and overburdened populations are more prevalent within the study area than across the four county Puget Sound Regional Council geography (Snohomish, Kitsap, King, and Pierce Counties). Overburdened populations are most concentrated north of the King-Pierce County line within the SR 167 Master Plan study area. Most vulnerable populations are likely to have safety concerns, technology barriers, and cost and time constraints.

Land-Use, Housing, and Employment Summary

The study area includes the largest manufacturing and warehousing/distribution cluster in the Pacific Northwest region. Over one-third of current study area employment is concentrated in manufacturing centers. There are about 236,000 housing units and 401,500 jobs in the study area today.

By 2050, forecasts predict an estimated 433,000 housing units (an 84 percent increase) and 645,300 jobs (a 61 percent increase).

Freight Network

SR 167 is the second busiest freight corridor in the state, carrying 10,000 trucks daily. This truck flow represents 10-20 percent of all vehicles on the freeway. Only about 9 percent of freight trips along the corridor pass through, so most trips start and end within the study area. Daily freight volumes are estimated to grow by at least 50 percent by 2050.

Active Transportation Network

The pedestrian and bicycle network is not complete and is disconnected due to suburban development patterns. Approximately one-half of local roads and connections to SR 167 have sidewalks on both sides of the street and more than one-half completely lack bicycle facilities. Several regional trails in the study area provide a strong connection between homes and businesses, particularly for bicyclists.

Transit Network

Transit ridership and services are concentrated north of SR 18. The highest ridership routes are oriented north-south, and include:

  • Sound Transit’s Sounder S Line train
  • King County Metro Bus Routes 150, 160, and 165

By 2050, there will be a lot more transit investments within the study area. King County Metro and Pierce Transit will increase east-west trips connecting to the Sound Transit Link light rail extension.

Travel Patterns

Based on data, a slight majority of trips on SR 167 begin or end south of SR 18. More people live north of SR 18. More jobs are located north of SR 18.

Most truck trips have an origin or destination within the study area. A key pattern for long-distance truck trips is between eastern Washington and the Port of Tacoma and other locations further south along I-5 via SR 167.

Active transportation trips (people who walk, bike, and roll) are more concentrated around Regional Growth Centers.
