Crews with Kraemer North America are assembling the bridge structure on the side of freeway near the 145th Street southbound off-ramp.

Driving Interstate 5 between Seattle and parts north, you may have spotted it. And soon, you won't be able to miss the new bridge structure set to span the freeway at North 148th Street.

In an update on social media last week, the city of Shoreline said that crews are currently assembling the structure for the new 148th Street Non-Motorized Bridge on the west side of I-5. Sometime this fall, the bridge span will be lifted up and placed on the piers.

Along with the 300-foot span with its side-by-side arches and supporting cables, the project includes a 16-foot-wide shared-use path, landings and connecting trails.

The pedestrian bridge is designed to create a safer and more accessible route for those walking, biking and rolling between both sides of the freeway, and will help connect people with Shoreline's two light-rails stations. The bridge was designed by LMN, with KPFF as the structural and civil engineer.

The 300-foot span with its side-by-side arches will connect walkers and riders to Shoreline’s two light-rail stations.

The total project cost is around $40 million.

Massana Construction began work in December 2023 on Phase I of the bridge project, working on the east side of I-5 next to the station. That work should be wrapping up.

On the west side, Phase II began in June 2025. Crews with Kraemer North America have been assembling the bridge structure on the side of freeway near the 145th Street southbound off-ramp.

The city says that, when the bridge is assembled and ready to be placed, I-5 will need to be closed completely. This is set to happen sometime in late October or early November, and will take place overnight to reduce traffic impacts.

Bridge opening is expected in early 2027.

Other members of the project team include Landau Associates, geotechnical engineer; Land Meets Water, arborist; KPG Interdisciplinary Design, landscape architect; Furtado & Associates and Ott-Sakai Associates, additional civil engineers; and Stepherson & Associates, project outreach.
