I remember when Loop 1604 was named "The Death Loop."
Ahhh, the Death Loop. LOL. I think the name still applies, AFAIK. Completion only made it accessible to more vehicles.
AAAAAUUUUUUGGGGHH!
Sorry, but you mentioned 1604. Sometimes..35 coming north out of SA...is worse. It got to the point where I would just take 46 west out of New Braunfels...and then take 281 into SA. I had to drive to Lackland from Bullis one day and I though I was gonna die when some girl in a jeep lost control on 410.
It was a fun summer. I had a part time job at Schlitterbahn. The first couple of weeks and the last couple of weeks were nothing but sority girls showing up at the park.
