    Drivers will need to share the road and plan for slowdowns as thousands of bicyclists take to state highways and local roads this weekend.

    As many as 10,000 bicyclists are expected to ride in the annual Seattle to Portland Bicycle Classic Saturday and Sunday, which leaves from Seattle at 5:30 a.m. Saturday.

    The Washington State Department of Transportation says bicycles are considered vehicles under state law, and though they may travel slower than the speed limit, they still have a right to use the road. Read a FAQ about driving safely with bicyclists here.

    In turn, bicyclists are also expected to follow Washington’s bicyclist rules of the road

    The ride will start from the University of Washington's E-1 Parking Lot along Montlake Boulevard Northeast.

    WSDOT said based on previous STP rides, congestion and delays are expected at the following times and locations:

    • Early morning Saturday, July 14, on SR 7 in Pierce County
    • Midmorning to afternoon, Saturday, July 14, on SR 507 in Thurston and Lewis counties
    • Early Sunday, July 15, on SR 411 from Castle Rock to Kelso
    • All day Sunday, July 15, near the SR 432 and SR 433 Lewis and Clark Bridge

     

    The STP route follows state highways and local roads in these areas.  See a map of the route at this link.

Riders crossing the bridge on Saturday will not have a bridge escort and are expected to ride with traffic.
