Prepare for a busy weekend due to Seafair.

From King County Metro:


Some King County area transit service will be affected by community, sports and construction events and activities this weekend. 

Even when it is affected by crowds, traffic, construction, temporary reroutes or delays, riding transit is still a great way to get around our community and to most local events and activities, where there is usually congestion and limited parking. 

Transit reroute start and end times, routing, and other details may be subject to change.  Use regularly published timetables, allow plenty of travel time and expect possible delays.

Text for departures
When you are at or on your way to your stop, text your transit stop ID to 62550 to find out when the next transit service is scheduled at your stop.

Fleet Week highlights
Military members in uniform or with ID ride free 8/1-5

Service members not in uniform, please show military ID to the transit operator upon boarding, or to fare inspectors when asked. Valid forms of military ID include a Veteran Health Identification Card, a Uniformed Identification Card or a DD-214.

All other transit riders are required to pay a valid regular fare.

Riding transit to Hydro events – through Sunday
Route 50
Ride regular Route 50 service at any time to get near the Hydro venue.

On Saturday and Sunday, August 4-5, Metro will add trips to the Route 50, providing service every 15 minutes between 10:00 AM and 6:00 PM for passengers traveling to the hydro races.

Route 50, which otherwise normally operates every 30 minutes, serves Genesee Park near the Stan Sayres Pit on Lake Washington, and connects with Link light rail at Columbia City and Othello stations.

Use the regularly published schedule, then expect more frequent service.

Text your Route 50 stop ID to 62550, and expect the next bus to bus at your stop about every 15 minutes.

Other nearby service
Other transit service that travels closest to Genesee Park includes Metro Route 7 at Rainier Av S and S Genesee St, and Link light rail at Columbia City Station.

Other weekend highlights
Mariners games through Sunday
Expect possible transit service delays in the SODO area due to traffic, crowds and congestion associated with Mariners games at Safeco Field this weekend.

Link light rail and most transit routes that serve downtown Seattle go to within a few blocks of Safeco Field, or connect with routes that do.

Metro Route 21 is rerouted off of 1st Av S between S Holgate St and Edgar Martinez Dr S, two hours after the start - and until one hour after the end - of each Mariners home game. Start and end times vary.

Magnolia Summerfest and Seafair Parade

Trailhead Direct – seasonal weekend service to hiking trails
Trailhead Direct – Issaquah Alps and Mt Si service will travel via SR-520 during this weekend’s I-90 closures.  No regular stops will be missed. Use the regularly published schedules, but allow plenty of extra time and plan for possible delays.

Riding Trailhead Direct requires payment of a regular Metro fare in both directions with cash, ORCA or the Transit GO mobile app.

Hike safely.  Take plenty of water; let someone know where you are going, and be aware that cell service availability may be limited.

Three Trailhead Direct routes provide service to the Issaquah Alps, Mount Si & Mt Teneriffe, and Mailbox Peak trailheads.

Transit service during unexpected or civic events
In areas where there are transit service disruptions due to crowds, traffic, weather or civic events, transit riders are advised to
- Be aware of conditions in their immediate vicinity, such as street closures, detours, police directions, etc.
- Be prepared for delays or to make revisions to travel plans, such as traveling at a different time or using a different bus stop or route, depending on specific circumstances.
- Be prepared for unexpectedly revised traffic or routing, and for delays in transit service.
- Know the alternate stops or routes that may be in the vicinity of starting points and destinations.

Such events may be scheduled or unexpected, and may disrupt normal travel patterns or activities even outside of the event area.

While every effort will be made to keep riders informed of Metro’s service status, depending on the time and the nature of such events, Metro may not be able to provide real-time information or service updates via email or text.

Metro will also be following police direction or other applicable protocols, with safety as the first concern, and will work to maintain or restore service as soon as possible.

Event start and end times and other details may be unknown or subject to change.

For non-transit traffic or other local updates, check media sources, follow @seattledot or visit
 or other relevant sites.

Riders’ patience during these types of events is appreciated.
