Welcome

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.


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.


Working with the community

Since 2018, we’ve reached out to area residents, schools, churches, businesses, community groups, and organizations to learn about their priorities for people who live, walk, bike, drive, and ride transit on Issaquah-Pine Lake Road.

In fall 2018, we elicited feedback on our preliminary design through an open house and online survey, and the input we received has impacted our 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. Click here to download a PDF (33 MB) of the full 30% design, or view the video below for a simulation of the proposed improvements.

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
  • Adding right-turn pockets and left-turn lanes where necessary, for a total of 3 lanes between SE 32nd Way and SE Klahanie Blvd, and 5 lanes between SE Klahanie Blvd and SE 44th St
Improve safety for all users
  • Adding a landscaped buffer to separate sidewalks from roadway
  • Installing a new signal with crosswalk at SE 37th Pl for pedestrians crossing to the bus stop
  • Increasing roadway lighting
  • Building a raised landscaped center median at select areas of the corridor
Incorporate water quality upgrades
  • Creating flow-control and water quality improvements within Laughing Jacobs Basin
  • Adding fish-passable culverts at Laughing Jacobs Creek and Stream C




Next steps

The Issaquah-Pine Lake Road Improvements project is currently at the 30% design phase. Between December 2019 and February 2020, we shared the 30% design with the public through interviews with key stakeholders, an online survey, and a community meeting held on the corridor. We're currently reviewing the feedback we've received.

The City will continue to ask the community for feedback throughout the project design, and the input collected will influence the options carried forward. Once the design is finalized and the nearby Issaquah-Fall City Road project has completed construction, the City will acquire necessary right of way and begin construction.

    Survey now closed – thank you for participating!

    Thank you to all those who voiced your input in our online survey between January 13 and February 9, as well as the 70+ people who attended our community meeting on January 22! We’re reviewing your comments on the 30% design to see how we can work to incorporate suggestions where feasible. Later this spring we’ll be presenting the 30% design and our summary of feedback received to Sammamish City Council.
