Beginning Wednesday Islanders will receive a survey that if filled out, will demonstrate the importance that I-90 has in their everyday lives.

The Washington State Department of Transportation is mailing out a survey to all Mercer Island residents and business owners asking about their use of Interstate 90. Starting Nov. 13, the survey will arrive in the mail.

As part of this survey, residents will be asked to complete a week-long travel journal by recording their trips across the I-90 bridges from Sunday, Nov. 17 through Saturday, Nov. 23.

Data collected from the survey will help inform WSDOT of the potential effects different I-90 tolling options between Seattle and Bellevue could have on Mercer Island residents and businesses.

For more see the sample below.

WSDOT is considering tolling options that could give Mercer Island a free or discounted trip on and off the island.

All survey responses are anonymous and require no identifying personal information. Returned surveys should be postmarked by Tuesday, Nov. 26.

The City encourages all residents and business owners to participate in this project.

Visit the DOT’s I-90 tolling website for more details.


CORRECTION: WSDOT said an earlier survey example had incorrectly shown two westbound return trips in each time slot. Survey instructions were correct but the example was not.

WSDOT is mailing postcards to residents showing the correct response to the example provided. Postcards should arrive in mailboxes by Friday. This does not affect the survey mailed to businesses.

If there is still confusion residents can contact WSDOT at 206-464-1190 or email
