If your day includes a drive on I-5, you probably have a few thoughts about where the trip could work better. WSDOT is inviting those experiences into a longer conversation about the region’s transportation future, with an online survey open through Nov. 13.
The survey is part of the Cascadia Program, which brings together planning for Washington’s I-5 corridor and a possible high-speed rail connection between the Vancouver, B.C., Seattle and Portland metropolitan areas.
People who travel through Snohomish County can weigh in on the daily trips they know best, from commuting and deliveries to appointments and visits with family.
What WSDOT is studying
In its Nov. 5 announcement, WSDOT points to a projection of 3.4 million additional people in the Cascadia megaregion by 2050. The agency says it is examining I-5 improvements while studying whether high-speed rail could offer another way to travel. That is a forecast and a planning effort, rather than a construction announcement.
The program’s engagement page describes the I-5 Master Plan as a roadmap for transportation investments through 2050. It covers the highway’s 277 miles in Washington and looks at safety, maintenance, reliability and connections to other travel options.
The rail work is also at the planning stage. WSDOT says it is not selecting a preferred route or specific station locations now. The proposed service would complement Amtrak Cascades. It does not establish a new station in any of our towns.
Both planning documents are expected in 2028. WSDOT cautions that completing and implementing the I-5 Master Plan depends on future funding. The planning timetable should not be read as a rail-service opening date.
How to take part
The survey introduction estimates eight to 10 minutes to complete it. English, Spanish, Vietnamese and Chinese options are displayed. The first question asks for a home ZIP code or postal code.
The questionnaire asks about transportation priorities and travel experiences. WSDOT says the feedback will help inform its recommendations. You can read the program information before starting and describe the trips you make regularly, the connections you rely on and the problems you would like planners to consider.
Nov. 13 is the last day listed on WSDOT’s engagement page. The page does not give a closing hour, so submitting ahead of the final evening is a sensible way to avoid missing it.
