Is it possible to find archive footage from traffic cameras (Travis County, Texas)?

Alright, long story short, I was rear ended. However, due to the stop and go nature of the traffic at the time, after pulling into the lane the car in front stopped so I was stationary with my car at a bit of an angle in the lane.

The woman behind, obviously distracted, pulled forward after a couple of seconds and rear ended me. However, because the damage was on the corner of my bumper rather than in the center her insurance company is claiming I am at fault, and my insurance company is less than optimistic about winning an arbitration.

So… what I really need is video footage. There is a traffic cam located near the intersection where the collision occurred. TXDot claims they don’t keep any archives (which surprises me). But since it is a public feed I suspect that some geek will have an archive. So, how bout it, anyone know of any uber cool TXDot web cam archives out there?
