A pair of non-injury crashes snarled state Highway 500 at Stapleton Road Friday morning.
Both crashes (one in each direction) were reported just after 8 a.m., said Trooper Will Finn, spokesman for the Washington State Patrol.
Finn said a total of six cars and one semi were involved in the crashes. No one was reported injured, but one person needed a tow truck.
Lanes were cleared around 8:30 a.m. but the crashes caused traffic backup in the area, Finn said.
