An article in The Seattle Medium describes the major state roadway projects underway in the Puget Sound area, including an expansion of N 145th Street and two new roundabouts. "The City of Shoreline also has the arrival of Link light rail with Sound Transit looking to open two local stations in 2024." The article also notes that project work is gearing up at "a time when more good paying jobs are needed."

"The existing squared intersections on both sides of the interstate will be replaced with roundabouts. Shoreline leaders state that the design as one that will 'improve safety for pedestrians and bicyclists by separating them from vehicle traffic at well-marked and lighted crosswalks and reducing crossing distances,' while also providing increased throughput for vehicles."

According to the article, "For bikers, the upgrades to the I-5 overpass include a 2-way protected bike lane next to the sidewalk along the north side." But "Transit lanes are not included in the project design. Also no room will be provided along 145th Street for any dedicated bicycle facilities with this project."
