A 29-year-old woman driving the wrong way on Interstate 5 struck another vehicle head-on, injuring both drivers and snarling Tuesday’s morning commute.
The collision happened about 4 a.m. near Port of Tacoma Road.
Troopers said the woman was traveling north in southbound lanes when her Jeep hit a Mazda driven by a 21-year-old man.
Both drivers were taken to St. Joseph Medical Center. The woman appeared to have suffered a broken ankle. The man suffered serious injuries, trooper Todd Bartolac said.
Troopers were not immediately able to speak with either driver, so it was unclear how the crash occurred but the woman may have been under the influence of alcohol or drugs.
Both vehicles were totaled.
The right freeway lane was blocked, causing traffic backups. Lanes reopened at 7:25 a.m.
In addition, morning rush-hour traffic was worsened when someone dropped a rock off a freeway overpass in Fife about 6:40 a.m.
The rock broke through the windshield of a car driving below, but no one was hurt.
Backups stretched to state Route 18, according to the state Department of Transportation.
