The Route

Course Hours

7 a.m. to 11 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 SR 99 Viaduct northbound and the  I-5 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 SR 99 Viaduct - Opens at 7 a.m. and closes at 9:30 a.m. All riders must be off the Viaduct by 11 a.m.
  • Access to I-5 Express Lanes - Opens at 7:20 a.m. and closes at 9:30 a.m. All riders must be off the I-5 Express Lanes by 10 a.m.
Give yourself some extra time to make these time cut offs. These are Hard Closures and there will be no exceptions.
