Both directions of Highway 18 were closed between Interstate 90 and the Issaquah-Hobart Road exit after a serious-injury collision, according to the Washington State Patrol.

The crash involved a semi-truck and a pickup, Trooper Rick Johnson said on Twitter. A photo he tweeted showed a white pickup with the top sheared off.

Lanes in both directions were open shortly before 1:30 p.m., according to the Washington Department of Transportation.
