WALNUT CREEK (KRON) — Interstate 680 was briefly shut down Monday morning due to horses on the freeway in Walnut Creek.
The horses were reported at around 7:38 a.m. on northbound I-680 at Castle Crest Road, according to the California Highway Patrol.
Authorities have rounded up the horses and the lanes were opened by 8:30 a.m.
Steve Burdo with Contra Costa County Animal Services says the animals broke through a fence about a mile away.
The pair adhered to the vehicle code and used an on-ramp to enter the highway.
Burdo says the horse, a gelding named Striker, appears to have led the breakout. He says Hank the mule is more of a follower.
