Halloween in June? Not quite – fog from liquid nitrogen is part of ongoing construction

If you’ve taken the westbound SR 520 off-ramp to Montlake Boulevard recently, you may have noticed some fog. Never fear, this is part of ongoing construction! Crews are excavating an access pit in this area to help replace a waterline that runs under SR 520. Water-saturated soils kept sliding in while we dug, so we’re freezing the ground with liquid nitrogen. Crews installed underground pipes to carry liquid nitrogen, creating a frozen dam that allows us to continue digging. The liquid nitrogen vapors are harmless, so don’t get spooked! You can learn more about this process in our latest video.

A construction pit next to a highway off-ramp is surrounded by fog rising up from pipes around the pit.

Burb's Burgers food truck coming to Montlake!

WSDOT has selected the Huxley Wallace Collective’s proposal to operate a food truck by the name of Burb’s Burgers in the Montlake area. The food truck will be located on a portion of the former Montlake Market property just off East Roanoke Street, west of the intersection with Montlake Boulevard. Burb’s Burgers will follow all applicable guidelines for operating in the current COVID-19 environment, and plans to be open seven days a week for the duration of Montlake Project construction – until approximately 2023.

A map of the S R 520 Montlake Boulevard Interchange. A green dot on East Roanoke street, west of Montlake Boulevard, is labeled Food truck location.

The Huxley Wallace team writes: “The menu includes breakfast options, amazing cheeseburgers, sandwiches, shakes, fries, and weekly specials. We plan to create a beautiful outdoor dining space complete with beer garden and special guests to be enjoyed year round. Prior to Burb’s Burgers, Huxley Wallace Collective has concepted, developed, and operated a number of award-winning food and beverage establishments across the Seattle area including Skillet, Westward, Great State Burger, and Quality Athletics.”

A black, white and orange food truck is parked on the side of a road. It's labeled Burb's hamburgers.

For updates about the opening date and additional information, visit or @burbsburger on Instagram.

Thank you again to the more than 500 community members who participated in last year’s survey about this neighborhood market/food service opportunity. Those responses informed WSDOT’s selection criteria and will shape the offerings to come. Your collaboration, and the effort of 43rd District legislators in response to the community’s interest in maintaining a food service and gathering space in the Montlake neighborhood, helped make this opportunity possible.

Low-risk construction activities resume on SR 520 Montlake Project

WSDOT temporarily paused most construction projects in the state on March 26 in response to the COVID-19 pandemic. In keeping with Gov. Inslee’s phased approach to reopening Washington’s economy, the SR 520 Montlake Project resumed key low-risk construction activities on Monday, May 18.

Looking over eastbound SR 520 in Montlake. The highway is empty. In the background is a construction site with large cranes.

As we restart construction, all crews are required to adhere to specific safety protocols that help ensure the health and safety of workers on the site.

The initial activities in this phase of low-risk work include:

  • Removing trees in the median along Montlake Boulevard; vegetation will be replanted when the project is complete. (See more details below.)
  • Removing the former Montlake Market building and 76 gas station; this work will begin later this week and last several weeks. (See more details below.)
  • Working near the westbound off-ramp to Montlake Boulevard in preparation for a waterline replacement.

Future phases of work later this spring and summer, pending additional direction from the Governor’s Office, include:

  • Temporarily closing Montlake Boulevard over a weekend to complete utility work along Montlake Boulevard.
  • Closing SR 520 for a weekend to shift traffic lanes to provide additional work space for construction of the Montlake lid foundations and supporting walls.
  • Continuing installation of a temporary work bridge on Lake Washington.
