Any tips for getting out of the medical center at night during the rodeo?

I work in the medical center and get off work when everyone is leaving the rodeo. I always get stuck wading through rodeo traffic (j-walkers and drunk drivers oh my!). I just want to get home before my SO, who is on an opposite schedule, falls asleep so we can have a little more than just the weekends together till this is all over.

So from the med center to Clear Lake area, anyone have any tips to get to 45 S a little quicker and safer than Fannin?
