I know exactly where this bridge is. It is right by brightleaf square in Durham, NC. It is on a road that some might use to get from 85 to 147 or from Durham regional medical center to 147. It actually isn't far from Duke University or Durham bulls stadium. I used to drive under this bridge all the time (daily driving, no trailer). This is a railroad bridge in a high foot traffic areas with a crosswalk a couple hundred yards before the bridge. The speed limit here is only 25 mph. From the looks of the video I'd bet they were driving faster.
