Forty-two King County Metro Transit and Sound Transit bus routes, including routes through the Central District, will be affected by major events on Saturday. Street closures for the Fremont Fair and the Rock & Roll Marathon will force these buses to operate on reroute, and delays due to traffic are expected.
The marathon affects Rapid Ride C & D Lines, 1, 2, 3, 4, 5, 7, 8, 10, 11, 12, 14, 16, 21, 26, 27, 28, 36, 40, 43, 47, 49, 50, 66, 70, 82 (Friday night only), 99, 120, 124, 125, 131, 132, 358, ST 522, ST 545, ST 550 & ST 554. The fair and accompanying Solstice Parade will affect routes 26, 28, 31, 32 & 40. More information on the reroutes is available on the Metro website.
Drivers and bus riders should take a look at the Rock & Roll Marathon course map to avoid street closures and take note of potential traffic.
More information from King County Metro:
Most buses that travel through downtown Seattle will be rerouted until about 10 a.m. Saturday, however some routes will be rerouted until 3 p.m. Saturday. Most buses heading into Seattle from the north will turn back at Olive Way near Convention Place Tunnel Station (CPS). Most buses traveling toward downtown Seattle from the south will turn back at South Royal Brougham Way near the SODO Busway and Stadium Link light rail Station.
Riders who need to travel through the downtown Seattle core are encouraged to travel via the Downtown Seattle Transit Tunnel during the event. Using regular transit service in the tunnel is a good way to get through the downtown area quickly.
Bus riders who want to travel between CPS and Royal Brougham can ride Metro routes in either direction. Riders who want to get to other downtown destinations have additional options. From Stadium Station, Link goes as far north as Westlake Tunnel Station. All buses northbound in any tunnel station go as far as CPS. For southbound riders traveling from CPS, all buses go at least as far as International District/Chinatown Station.
Metro will operate a free shuttle bus about every 20 minutes from 5:30-10:30 a.m. between South Alaska Street and South Henderson Street. Most other Rainier Valley bus service will not travel south of Mount Baker Transit Center during the event. Link light rail will operate its normal Saturday service and is a great way to get to and from the Rainier Valley.
