A crash involving an 18-wheeler has closed the eastbound ramp on the President George Bush Turnpike that leads to the northbound lanes of the Dallas North Tollway.
The truck struck a guard rail on the overpass and is partially hanging over the edge.
The 18-wheeler is the only vehicle involved and there were no injuries, according to State Trooper Lonny Haschel.
The closure is expected to last into the afternoon, possibly through rush hour, as crews first unload and then right the trailer.
At 4 p.m., officials have not said when the road will reopen.
