Update on WSDOT's purchase, use of Montlake Market property

We held a public meeting Thursday evening (May 23) to update the community on the SR 520 Montlake Project and how it will affect the Montlake Market and 76 gas station. We informed meeting participants that WSDOT will take ownership of the property in June, and that WSDOT leadership determined the market cannot practicably be preserved during SR 520 construction. We also discussed a new legislative directive to WSDOT that seeks to establish a temporary market or food service in Montlake during Montlake Project construction. Read more about this on our News and Updates page and view the meeting's presentation slides (pdf 3.6 mb).
