Recap of Jan. 30 Montlake Market public meeting, online survey now available

More than 130 people attended our public meeting Wednesday evening (Jan. 30) to hear an update on WSDOT’s upcoming Montlake Project and our efforts to see if the Montlake Market building can be preserved during SR 520 construction. As part of the meeting, about 40 attendees discussed potential scenarios and tradeoffs related to the market-preservation effort, and then took a short survey to share their views with WSDOT.

We’ve placed the meeting materials and survey online for those who couldn’t attend and would like to give us their feedback. Here are links to:

  • The online survey, which will be open until 5 p.m. Thursday, Feb. 14.
  • The meeting handouts (pdf 590kb), which include the agenda, a list of more than 50 ideas suggested for preserving the market, and a chart of potential market-related scenarios and tradeoffs.
  • The presentation slides.
  • Survey results (pdf 604kb) from attendees of the Jan. 30 meeting; all results through Feb. 14 will be posted online and provided to the SR 520 Program team and WSDOT leadership to help inform the decision about the market building.
  • Our answers to questions (pdf 250kb) community members posed on this topic at our Nov. 7 meeting.

Soils testing completed on Montlake Market property

We recently conducted test drilling in Montlake where the Montlake Market and 76 gas station are located, and found contaminated materials in the soil and groundwater. We plan to acquire this property later this year to enable construction of improvements to SR 520 as part of the upcoming Montlake Project. You can read the full soil-testing report (pdf 14mb) on the SR 520 website. We’re working closely with technical experts to learn more about the contamination and determine the next steps.  We’ll keep the public informed as we know more.

Program Overview

The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. The construction program's planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
