How is it that U.S. Highway 56 through Overbrook and Baldwin and over to Gardner has a 55 mph speed limit when different highways that pose even more dangerous road types and conditions - such as steep shoulders or no shoulders, curves and hills - have 65 mph limits?

According to the Kansas Department of Transportation, a speed limit largely is determined by the speed at which most drivers travel. In making speed decisions, drivers are more influenced by traffic and road conditions than speed limit signs, KDOT said.

Therefore, KDOT engineers study traffic flow under normal, off-peak driving conditions to determine the average speed at which 85 percent of drivers are traveling. The speed limit can be adjusted based on factors such as accident history, road design, parking, pedestrians and curves.
