The City of Sammamish is planning improvements to Issaquah-Pine Lake Road SE from SE 32nd Way to SE 44th Street. The project will aim to improve traffic flow and safety for all users.

Please join us at our community meeting at Pine Lake Middle School on Jan. 22 at 7 p.m. to learn more about the project and share your ideas! Or if you can't join us in person,  click here to fill out our survey and share your input.

Why are improvements needed?

Issaquah-Pine Lake Road is a critical corridor for existing and new residential developments, multiple schools, and commercial areas. With these competing demands on the roadway, travelers experience significant delays during peak travel times.

In May 2018, the City of Sammamish began the Issaquah-Pine Lake Road Improvements Project. During the preliminary design phase, the City considered alternatives and developed a preliminary design for Issaquah-Pine Lake Road between SE 32nd Way and SE Klahanie Boulevard. The project area has since been extended to SE 44th Street as part of the 30% design.

What we've heard so far:

  • Desire to see improvements made on Issaquah-Pine Lake Road to help reduce congestion (particularly during school drop-off and pick-up times) and increase safety

  • Acknowledgement that the existing roundabout at SE 32nd Way is not working well, and broader preference for traffic signals at intersections instead of roundabouts

  • Emphasis on improving intersections and turns from and onto Issaquah-Pine Lake Road for all users

  • Appreciation for pedestrian infrastructure proposed in preliminary design, including improved sidewalks and crosswalks

  • Support for bike lanes as proposed in preliminary design

  • Interest in seeing improvements on Issaquah-Pine Lake Road outside the project area as well, especially from SE Klahanie Blvd to Issaquah-Fall City Road

What improvements are proposed?

We’re proposing improvements in our 30% design that incorporate feedback we've heard and help achieve our project goals.

Project goals What we've incorporated in the design
Create a multimodal roadway for people who walk, drive, bike, and ride public transit
  • Maintaining one travel lane in either direction from SE 32nd Way to SE Klahanie Blvd
  • Maintaining two travel lanes in either direction from SE Klahanie Blvd to SE 44th St
  • Adding a bike lane in each direction and sidewalks where needed
Improve intersection performance
  • Replacing the roundabout at SE 32nd Way with a traffic signal
  • Adding a traffic signal at SE 37th Place
