In February 2009, the Mountlake Terrace Transit Center opened. It connects local, commuter, and regional busses serving about 40,000 passengers a day and was expanded from a 338-stall park-and-ride lot. With capacity for over 1,000 cars, the Transit Center features a five-level parking garage with 900 spaces, glass elevator, covered bus shelters, bike lockers and racks, ample lighting, and closed circuit cameras.
The Mountlake Terrace Transit Center connects via covered pedestrian bridge over the freeway to Sound Transit's Freeway Station located in the median of Interstate 5. The Transit Center is located at 6101 236th Street SW.
