Drivers crossing the Lewis and Clark Bridge should expect delays up to 20 minutes Sunday for cyclists riding in the Group Health Seattle to Portland Bicycle Classic, according to the Washington Department of Transportation.
Washington State Patrol troopers and other flaggers will stop southbound traffic over the bridge in 15-minute intervals from 8:30 a.m. to 3 p.m. to allow cyclists to pass.
Flaggers will also be on hand Sunday at West Side Highway at Castle Rock, Lexington and Longview to direct traffic.
Organizers expect about 10,000 cyclists for the 200-mile Seattle-to-Portland ride, which celebrates its 31st anniversary this weekend.
The two-day ride begins Saturday morning at the University of Washington. Most cyclists spend the night in the Centralia-Chehalis area, but some ride far enough the first day to sleep in Longview and Kelso, and some ride the whole distance in one day.
