St. Paul is a single lane country road posted at 40 mph. The road changes elevation dramatically between two ridges in the terrain. It is very easy to exceed 50 mph when coasting down one side of either ridge. Town and state police like to sit at the bottom of a small "valley" between each ridge during morning and evening rush hour to catch people exceeding 50 mph. You should start braking at the top of either ridge, apply your brakes throughout the descent, and do not exceed 45 mph (which they seem to allow).
