Some general issues and/or suggestions:
- People want to know when they are on a toll road so we should use Toll in the name when there is an identical or similar number on the frontage road. This is especially important since the signs say toll on them most of the time
- Some square signs say Texas on them. Should they be SH-xx or TX-xx?
- Texas has in a some cases "preempted" US highways and normal Texas state highways with limited access toll roads. The frontage roads sometimes have the old number and/or a street name (like Research in Austin and Beltway 8 in Dallas). Wazers need to know which they are on and we need to preserve any street numbering associated with what is now the frontage road.
