Texas highway category re-arrangement

I'm trying to un-knot the highway categories of Texas on Commons. Right now, there are several strange designations, some of which are not plural, some of which are redundant, and some of which don't quite match the content of the category. I'm changing the following:

• Category:Texas Highways (redundant) — redirecting to Category:State highways in Texas
• Category:Texas State Highway (singular) — redirecting ({{Bad name}}) to new Category:Texas State Highways (i.e. the highways with route signs that are a number and "Texas" underneath)
• Category:Texas Farm Road (singular) — redirecting to new Category:Texas market roads (i.e. the roads that are the shape of Texas with "Farm" or "Ranch" in one corner); if someone can think of a better generic name for these, use that I guess)
• Category:Current Texas Highway maps (unclear what "Texas Highway" means; Interstates are mixed in) — redirect ({{Bad name}}) to new Category:Current maps of Texas State Highways
• Category:Old Texas Highway maps ("Old Texas Highway"?!) — redirect ({{Bad name}}) to new Category:Old road maps of Texas

• Category:Texas Historic State Highway shields (capitalized "Historic" for no reason) — redirect to Category:Old-style Texas State Highway shields
