Status

As of February 2026
Phase 2: 100% Design

The project is in Phase 2, design and construction. We are currently reviewing the 90% design plans and coordinating with area agencies to ensure the roundabout design works efficiently for all users.

Project Overview 

This project will build a roundabout at the intersection of Greenwood Avenue N with N 160th Street and NW Innis Arden Way. It is a mitigation requirement for development of Shoreline Community College. A new roundabout will replace the stop signs at the intersection to improve traffic flow along this route. 

160th and Greenwood Ave intersection design is an oval roundabout connecting the five streets in the area

Preferred alternative for the intersection design. 

Schedule

Design Development:        Q3 2023 – Q1 2024
Right-of-Way Work:            Q2 2024 – Q3 2024
Final Design                       Q2 2024 – Q1 2026
Project Advertisement:     Q2 2026 
Construction:                     Q3 2026 – Q1 2027 

Tree Impacts

This project will impact up to 14 trees. The arborist report for this project identifies 11 trees for removal and three additional trees that may need to be removed. We are working with arborists and designers to minimize tree impacts.

NOTE: The format of the arborist report does not meet current digital accessibility standards so we are unable to provide it on the City’s website. To receive a copy of the arborist report, please email Tavia Tan at ttan@shorelinewa.gov. 

Construction Impacts

While construction of this project will involve temporary lane closures in the intersection, local access to Shoreline Community College and residences on NW Innis Arden Way will be maintained through the intersection at all times. We will also be constructing the Hidden Lake Dam Removal Project during this time and NW Innis Arden Way will be fully closed at Shoreview Park. 

As with most construction projects, nearby neighbors may experience:

  • Increased noise, dirt, dust, and vibrations
  • Construction traffic and staging of large equipment in the area.
  • Lane closures
  • Parking restrictions

Community Engagement

Community engagement on the project began in 2019, with two public meetings held at Shoreline Community College to discuss design concepts for the intersection.

In September 2024, we invited residents to attend a third open house to learn about the current status of the project and plans for construction, and to ask questions of the project engineers. An online open house was also available for residents to provide feedback.

Overview and History 

Shoreline Community College built student housing on campus, completed in 2019. The College did a traffic study for the new housing. It showed that the City’s delay standards weren’t being met at the intersection of Greenwood Avenue N with N 160th Street and NW Innis Arden Way. The College was granted six years to improve the intersection from when the student housing building is complete and obtains a Certificate of Occupancy. 

City Council approved a City capital project to develop a design concept for improving the intersection. This project focused on:

  • Talking to the community
  • Completing traffic analysis
  • Selecting a concept that improves safety and mobility for all people

This work also evaluated whether replacing the existing stop signs with new traffic signals or installing roundabouts for the intersection would best meet those goals. After completing that work, the City selected the roundabout alternative and design and construct the project as a City Capital Project.
