UPDATE: The southbound of I-29 are now reopen.
Original:
The Andrew County Sheriff's Dept and MSHP have reported that southbound Interstate 29 at the 56-mile marker is closed due to an overturned semi-truck completely blocking the highway at the 48 mile marker in Buchanan County.
All traffic southbound is being diverted to Interstate 229. This also has the ramp from southbound U.S. 71 to Interstate 29 closed, and the ramp from Interstate 229 to southbound Interstate 29.
The ramp to go southbound at the 53 mile marker is also closed.
At this time, Sgt. Shane Hux with the Missouri State Highway Patrol Troop H, says a passenger in the tractor-trailer suffered minor injuries.
Hux says the wrecker needs to safely remove the vehicle and cargo from the roadway.
The Missouri State Highway Patrol will post updates on social media.
