Yes, even in Texas:

…local law enforcment officials have closed off local farm and country roads which would ease the traffic flow along the major evacuation routes. One friend of mine who lives in Angleton, 40 or 50 miles south of Houston and who is very familiar with the back roads was not allowed to use them; local law enforcement officials forced him back on to the major evacuation routes which lead to nowhere. They are virtual parking lots. There are numerous reports of people turning around and returning to their homes.
