Travelers on a Washington state highway captured video of an unusual traffic hazard -- salmon swimming across the street.

Terri Sue Potter recorded video Sunday showing multiple fish swimming across the shallow waters flooding a small section of U.S. Highway 101 in the Shelton area, reports the UPI.

Alexis Leonard, a fish hatchery specialist, also recorded video of the unusual phenomenon.

Leonard said the fish come from the Skokomish River and sometimes end up on roads and other areas when the nearly creeks flood during the spawning season.

‘If they're lucky, it'll meet up with the creek on the other side of the road, if they're not they're stranded,’ Leonard told CNN.
