Sixteen vehicles and three semi-trucks were involved in multiple collisions on Saturday morning on Interstate 90 two miles east of Cle Elum, and the westbound portion of the highway was closed for 4 1/2 hours. No major injuries were reported, according the Washington State Patrol. Jose Montoya Berrera, 50, of Carencro, La., was driving a semi-truck westbound near milepost 88 at 9:33 a.m. when he lost control, struck a guardrail and came to rest blocking the roadway in a curve. Due to conditions and the curve in the interstate, multiple other collisions occurred. The cause of the accident was speeding too fast for conditions, according to the WSP. Interstate 90 over Snoqualmie Pass westbound also closed Sunday evening near Easton because of multiple collisions, according to the state Department of Transportation.
