I was driving home today 9/10/21. I was getting on I-20 from 35W, and traffic was backed up so I stayed in the exit lane for campus drive. The driver of the truck in the picture used the shoulder to get further up in line and force his way into the lane I was in. I took the picture just before exiting on campus drive because I saw he had forced his way into the lane that did not exit. Driving like that was the full cause of the traffic jam. By the time I made it around to Anglin Ave and crossed the bridge over I20 the flow had started moving with no emergency vehicles or construction in site.
