A tractor-trailer rollover causes road closures.
A witness to the accident says it happened just north of Caney.
The Montgomery County Rural Fire Department says The cloverleaf ramp for US-166 West/US-75 Norths is closed but the US-166 West exit from the north and the south bound US-75 exit is still open. Drivers needing to travel in that area should find an alternate route.
