Sounds like quite a convoy. “About 1,000 vehicles,” according to the police chief. “Heavy traffic continues on the 610 Loop. Congestion has been exacerbated by major traffic collision. Please avoid the Loop. Lead vehicle of event is at the 59 and North Freeway. Tale of event has still not departed Fannin.” It looks like it started in one of the NRG lots, so if he means it was stretching from between 59 and 45 on the North Loop all the way around to Fannin on the South Loop, that’s massive. Nearly 20 miles.
