I plan on a round of measurements to see where I stand and see what needs to be replaced. I ordered my first round of parts yesterday, things that I will need no matter what.
As for FM1604, it used to be called the "Death Loop" because it was a two-lane road that ran out in the country and people were getting killed by cement trucks, etc. No longer...the city has engulfed 1604...it's now a 4-lane divided highway (mostly) around the city. To get to any cruising roads, you have to go farther out now...not much farther, though.
