DISCOVERY BAY, Wash. - One person was severely injured in a three-vehicle crash involving a motorhome on U.S. route 101 in Jefferson County on Tuesday afternoon, according to the Washington State Patrol.
Troopers and medics responded to the scene, about seven miles south of Discovery Bay, around noon after receiving reports of a serious crash.
Three crashed vehicles were found at the scene, including a motorhome that had rolled onto its side.
A woman in her 90s in the RV suffered an arm injury and was airlifted to Harborview Medical Center in Seattle, according to troopers.
The RV driver and another passenger were not injured.
Troopers said the semi-truck going southbound swerved into oncoming traffic to avoid hitting slowed traffic ahead.

The third vehicle, a car going northbound behind the RV, also swerved to miss the truck and was lightly damaged, according to troopers.
The semi-truck driver and car driver did not suffer any injuries.
The roadway is now open after being blocked earlier today.
