Coming down out of the mountains on the 70, there are "road construction" signs which set the speed limit at a highly unreasonable 55mph. This is especially bad considering you’re coming out of the mountains on a fairly steep down grade. It’s very difficult to maintain 55mph just because of the weight of most vehicles. Coming out of the last curve from the mountains (a left curve when heading West towards Denver), you will see a straight section of highway headed down into Denver. There will be a slight/subtle hill you pass over, and on the other side of that hill or rise, a police car will sit in the center median on the left with radar trained on all traffic coming out of the mountains.
