OLYMPIA — Drivers should plan for extra travel time Saturday and Sunday when 8,000 bicyclists ride western Washington’s state highways and roads for the 2019 Kaiser Permanente Seattle to Portland Bicycle Classic.
Bicyclists are expected to ride through Thurston and Lewis county at mid-morning to afternoon Saturday on SR 507.
The Washington State Department of Transportation asks motorists to prepare for travel delays during the popular ride. As state driving laws periodically change, drivers may want to review the state driver guide and the driving among bicyclist sections.
Bicyclists should also be aware of their responsibility to follow Washington’s bicyclist rules of the road.
The Cascade Bicycle Club distributes a free pocket guide about state bike laws with support from the Share the Road license plate sales. To request a copy of the guide, email: email@example.com.
