All westbound lanes on Interstate 94 near the St. Croix rest area are back open after a crash involving a semitrailer truck blocked lanes Thursday morning.
Lanes reopened about 7:45 a.m. after being closed for about two hours.
Authorities shut down westbound lanes and diverted drivers off the freeway at the Hwy. 95 exit after the big rig rolled over about 5:30 a.m. Traffic was jammed as far back as Carmichael Road in Hudson, Wis.
Cleanup crews removed the truck from the traffic lanes and authorities were able to open one lane near Stagecoach Trail, allowing motorists to get through.
The truck driver was not seriously hurt, said Lt. Gordon Shank with the State Patrol.
No other vehicles were involved in the crash. Shank said it was not immediately clear what caused it.
