The Route


Course Hours

6 a.m. to 11:30 a.m.

Time Cut Offs

For most of the route roads will be local access only for vehicle traffic in cyclists' direction of travel (and fully open to vehicles traveling in the opposite direction). Some points along the route, including the I-5 Express Lanes, the SR 520 Bridge, and the I-90 Express Lanes will be entirely closed to vehicle traffic and open to riders for a set period of time. To support this rolling closure certain parts of the route will be subject to time cut offs: 

  • Access to I-5 Express Lanes - Opens at 6:10 a.m. and closes at 8:20 a.m. Riders on the longer loop should be off by 8:40 a.m. and all riders must be off the I-5 Express Lanes by 9:20 a.m.
  • Access to SR 520 Bridge - Opens at 6:20 a.m. and closes at 9 a.m. All riders must be off the bridge by 9:45 a.m.
  • Access to I-90 Express Lanes - Opens at 7 a.m. and closes at 10:20 a.m. All riders must be off the I-90 Express Lanes by 11:20 a.m.
Give yourself some extra time to make these time cut offs. These are Hard Closures and there will be no exceptions.
