Alamo Heights has recently posted 25 mph signs throughout the entire area including Broadway, New Braunfels, and residential streets. The signs read, "25mph unless otherwise posted." The tricky part is that they are almost always immediately followed by a 30mph sign. Where one zone begins and the other ends is obviously vague. I’m not sure if this is the case for Terrell Hills as well, but my mother and I were pulled over on Elizabeth Rd. driving towards Broadway for driving 32mph. The officer was polite, but stated the 25mph signs were up and he gave us a warning. He should have checked the area first, though, because we went back and carefully searched the area for the sign. It had not yet been put up on the street. It was placed the next week.
