A section of Interstate 80 in Liberty is back open after a semi rolled over early Saturday morning.

The ramp from Route 11 to Interstate 80 westbound had to be shut down while crews worked to upright a semi truck and remove it from the road.

It's not clear what caused the truck to flip or whether the driver was injured.

Both the eastbound and westbound lanes are back open as of 10 a.m. Saturday.
