Community Information

Metering Points & Vehicle Valves


In the Mt. Baker/Genesee Community there will be two North/South Metering Points where Seattle Police Officers will be moving traffic North and South when there are gaps in runners and it is safe to do so.  See below for these two locations.  Expect and plan for delays.

  • 38th Avenue S. & Genesee Street
  • 50th Avenue S. & Genesee Street


Vehicle Valves will be in place to make sure the community can access key streets and cross the course in vital intersections.  See specific the Vehicle Valve access map below for more detailed info.

Madison Street Valve (Madison Park Area)


Due to unforeseen complications, we have had to terminate the MLK Vehicle Valve.  For residents needing to get in & out of the Mt. Baker/Genesee  Area, please use the metering points listed above, or see below for detour routes that Seattle PD will be executing tomorrow to get everyone to where they need to go.  We apologize for the inconvenience and appreciate your patience and understanding.

  • Northbound traffic from MLK and Rainier  will either be directed west on Alaska to Columbia.  They can either take I-5, 15th Ave S. or Beacon to get North. OR residents can take Alaska East to get to 38th and get metered north across Genesee.
  • Southbound traffic will be detoured west on Jackson to 12th Ave to the Jose Rizal Bridge that will travel over Dearborn.

Road Closures

Most road closures and detours will be in effect between the hours of 6:00 am and 3:00 pm. At 6:00 am, Police and event personnel may implement a soft closure along the entire race course. At most points along the course, pedestrians and bicyclists may cross the course during safe gaps in runners. Please follow the discretion of a traffic controller if present. After the race starts the streets will reopen on a rolling basis as soon as the last participant has passed and all course support materials have been removed. Streets along the earlier miles of the route will open earlier than roads along the end of the route. Please review the course map and road closure grid for more information. Residents and businesses located near the race course are urged to plan ahead and to be aware of road closure schedules and alternate access routes.

Freeway and Ramp Closures

On Sunday, freeway and ramp closures associated with the courses may impact your travel on race day.  Please note, Interstate 5 will remain OPEN, in both directions. Please review our road closure grid for more information. Note, these closures and times are subject to change.

Road Closure Map

This interactive map outlines the road closures, highlights alternate routes and provides access information for popular destinations which will be affected by road closures during the race. At most points along the course, pedestrians and bicyclists may cross the course during safe gaps in runners. Please follow the discretion of a traffic controller if present. Google Maps does NOT take into account the road closures on race day.
