The Arizona Department of Transportation is encouraging drivers to be alert for bicyclists traveling along the shoulders of state highways throughout the Verde Valley this weekend due to a special event.

More than 1,000 bicyclists are expected to participate in a charity bike race on Saturday, May 17 and Sunday, May 18 from 7 a.m. to 5 p.m.

Drivers can expect to see bicycle riders on State Route 89A and SR 179. Minimal delays are expected but ADOT suggests drivers be prepared for slower traffic through the area.

State law requires a vehicle to maintain a three-foot gap when passing a bicycle on a roadway.
