Travelling West on Nolanville the speed in 40 mph but when you cross a bridge and curve left for a short distance it becomes 20 mph during school hours. The problem is after you pass the school, leaving the area, you are going downhill, very difficult to keep the speed down, and you are actually well away from the school property. The Nolanville PD place a car just past the Harker Heights city limits (the road is half HH and half Nolanville, so they can do that). Any car that just passes the school a block down must retain 20 mph, something that is very difficult to do. Many people can be ticketed there.
