Helpful Information for Commuters
NOTE: On June 3, 2017, the Washington State Department of Transportation (WSDOT) permanently closed the I-90 center roadway to all vehicles in order to allow construction of the East Link light rail line.
This closure also involves changes to some I-90 access ramps on Mercer Island: the reversible ramp at
77th Avenue SE closed permanently, and the westbound on-ramp via the tunnel at Island Crest Way is now restricted to HOVs only -- this means that SOVs accustomed to using that entrance will need to use another on-ramp.
Exploring new alternatives will be especially important for Seattle-bound morning commuters...please leave yourself extra commute time.

Additional Parking Options for Using Transit
- The City's existing TripPool van partnership with Metro can take riders the "last-mile" to the MI Park & Ride so that they don't need to use (or park) their own car.
- Metro also has a new, off-site pilot paid parking program at the Aviara Building
- The City has on-street commuter parking permits (Town Center) for residents only
- As many bus riders already know, the existing Sound Transit Park & Ride now fills up by about 7:00am on most weekday mornings; the City is working on identifying other parking stalls in the area that may be available by lease.
