Police in Tennessee say one person has been injured when a section of a concrete wall on an interstate highway collapsed and hit a car.
Chattanooga police said on Twitter the section fell Monday from an overpass on northbound Interstate 75 in Chattanooga onto I-24 below. Police tell the Chattanooga Times Free Press the injury was not believed to be life threatening.
The northbound lanes of I-75 are closed and traffic is being rerouted. Highway crews are working to remove the concrete section.
