In an effort to improve the speed and reliability of southbound buses along Interstate 5, late last year the Sound Transit Capital Committee approved funding for a bus-only shoulder lane between the Lynnwood Transit Center and the Mountlake Terrace Transit Center.
The Committee also approved funding for a feasibility study that would identify other potential opportunities to expand the program.
The I-5 bus-on-shoulder project is part of ST3’s Early Deliverables Program, a “series of improvements designed to improve existing transit services, reduce travel time through bus-on-shoulder operations and other related transit priority elements, and construct new park-and-ride facilities.”
ST says the 1.4-mile project is basically shovel ready, requiring minimal modifications including the addition of signage and lane striping, and improvements to pavement and drainage. For this project, ST is partnering with WSDOT, who has already completed the design and environmental review.
Construction on the project is anticipated to begin in the third quarter of 2018, with the operation of the lanes starting before the end of the year.
