I-25 closed southbound at highway 66 by Longmont
They are shutting down traffic southbound I-25, and diverting traffic east on highway 66. Also going to have fire rescue to go back north on the southbound I-25 lanes, since they are unable to get to the accident from the other direction. Sounds like a tractor trailer, and a couple of SUV's. But the traffic has been shut down for about 15 minutes, while they bring in enough state, county, and local police to help direct traffic.
