Same exercise as the last entry of this type. I couldn’t get the scale exactly right – this section of Round Rock / Pflugerville is actually quite a bit larger than the corresponding section of Central Austin. (There’s a “zoomed in” PDF of central Austin which I used for the original source – if I zoom in with a similar scale to this section of Round Rock, the lines are so thick as to be unusable).
Arterials which are part of the state highway system and thus get gas tax money:
- IH-35
- Parmer Lane (FM 734)
- RM 620
- SH 45
- FM 1825
- US 79
- FM 1431 (olive green in far upper left corner)
- FM 685 (north-south road colored olive green lower right corner)
(I can’t list all the roads on here that aren’t part of the state highway system because I don’t know many of their names – some of them don’t even currently exist – they are planned to be built sometime in the future by Round Rock and Williamson County).
Note that a much higher proportion of major roads in the southern Round Rock area are maintained by the state. In fact, it is unlikely that a resident of a neighborhood in this area will be able to pass the “HEB test”.
