PORTLAND, Ore. (KOIN) — Both directions of I-84 reopened in eastern Oregon early Tuesday morning after a 100-car pile-up closed the freeway Monday, according to the Oregon Department of Transportation.

The eastbound lanes reopened shortly after midnight, while the westbound lanes reopened around 6:30 a.m. Tuesday.

Officials initially said the stretch of I-84 east of Pendleton to Ontario would remain closed through Tuesday afternoon.

Dozens of cars piled up on the freeway Monday. All the crashes were along a mile-long stretch of I-84, with the largest crash possibly involving up to 20 vehicles.

According to Oregon State Police, more than 170 vehicles were stranded on the interstate Monday night.

Meanwhile, 71 people were reportedly taken to the Pendleton Convention Center after the crash.

Officials say winter weather is still impeding travel through I-84, so drivers should use caution.
