As of April 2023
Phase: Design

The City's design team achieved the 60% design milestone in August 2022.

Thank you for your participation in our third phase of public outreach! Phase three outreach was completed in fall 2021. We gathered your input on public art, urban design, and landscape features for the N 175th Street Corridor Improvements Project. Summaries of the online survey and community feedback are available below.

• Phase 3 Outreach Summary (PDF)

Public input indicates preference toward the use of natural materials and support for retention of street trees in the landscaping design.  Indigenous art and nature-inspired art are preferred with possible art installations sited at bus stops and sidewalks. The community also preferred keeping the pony statues at the 175th Street gateway sign.

Project Overview 

The 175th Street corridor is one of Shoreline's most active east-west arterials connecting the city's busiest north-south roadways. Shoreline has made it a priority to improve N 175th Street between Stone Avenue N and Interstate 5 (I-5) by making it easier and safer for all corridor users. The N 175th Street project, from Stone Avenue N to I-5, will support growth and promote safety and mobility by widening the roadway, constructing pedestrian and cyclist improvements along the full length of the corridor, and improving the intersection at N 175th Street and Meridian Avenue N.

The N 175th Street Corridor project area spans the length of N 175th Street between Stone Avenue N and I-5.

Council Approved Design Concept

On February 1, 2021, City Council approved the preferred design concept for the 175th Corridor Improvements Project. Using feedback received from over 1,500 participants through public outreach during the past two years, we were able to establish the community’s top three priorities for the corridor – (1) pedestrian walkability, (2) flow of traffic, and (3) transportation safety. The community provided feedback on how the initial design concepts met these priorities, and we combined this feedback with technical analysis to develop the preferred design concept. 

More detailed information on the traffic analysis, evaluation criteria, initial draft design concepts, and benefit measures can be found in the online engagement and survey site PDF. This PDF is an archive of the virtual open house hosted in summer 2020.

Stone Avenue N to Meridian Avenue N

The Council approved design concept is a hybrid of the draft design alternatives and provides a shared-use path in the westbound (uphill) direction and an on-street buffered bike lane, and a widened sidewalk in the eastbound direction (downhill) between Stone Avenue N to Meridian Avenue N. The uphill slope of the westbound direction limits the speed of people biking who wish to use the shared-use path, while those traveling eastbound (downhill) will have an on-street buffered bike lane which provides separation from both vehicles and people using the sidewalk. The design also includes a center median which allows for a new pedestrian crossing at Ashworth Avenue N and safety enhancements to the existing crossing at Wallingford Avenue N.

Meridian Avenue N to I-5

Corridor improvements between Meridian Avenue N and I-5 will include shared-use paths along both sides of the roadway. Additional coordination with Washington State Department of Transportation (WSDOT) is necessary to finalize the layout of this segment; however, shared-use paths will be used to enhance safety through the I-5 interchange.

Intersection of Meridian Avenue N and N 175th Street

The preferred concept for the intersection at Meridian Avenue N and N 175th Street is to improve the intersection with a new traffic signal system with longer turn lanes and improved bike and pedestrian facilities while minimizing environmental impacts at Ronald Bog and maintaining connectivity to the recently constructed sidewalks at Meridian Park Elementary.

Improvements on Meridian Avenue N will connect to the Meridian Avenue N Safety Improvements project, which will add bike facilities to Meridian between N 155th Street and N 175th Street in 2023. Additional information can be found on the Meridian Avenue N Safety Improvements project webpage.

Next Steps

With the preferred concept approved, the project has proceeded with design. Currently the design phase is fully funded through a federal Surface Transportation Program (STP) grant and Traffic Impact Fees. Additional funding is needed for construction.
