In February 2009, the Mountlake Terrace Transit Center opened. Expanded from a 338-stall park-and-ride lot, the Mountlake Terrace Transit Center connects local, commuter, and regional busses, serving about 40,000 passengers a day. 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 a covered pedestrian bridge spanning over Interstate 5 to Sound Transit's Freeway Station situated in the median of Interstate 5. The Transit Center is located at 6001 236th Street SW.
