Alligator Stops Traffic On Houston Bridge I have often wondered why something like this doesn't happen more often in Acadiana, and maybe it does, and I just don't know about it. Imagine, you are rolling along down Ambassador Caffery when you get the bridge over the Vermilion River only to find that there is an alligator blocking the roadway. Well, that same scenario played out in Houston Wednesday on the Fred Hartman Bridge according to ABC News 13 who shared the whole episode on their Twitter page. If you click here, you can see the report by Don Armstrong as the alligator blocked the right lane of traffic. He says that officers from several law enforcement agencies responded to the scene including officers from the Baytown Police Department, the LaPorte Police Department, and Precinct 8 officers from Houston Police.
