In this sense, Kansas City, Missouri is no different than most communities in the United States and Canada. In the last 70 years, the physical size of Kansas City has quadrupled while the population has remained relatively stable. (Put another way, every resident of Kansas City is on the hook for maintaining four times as much of the city as his or her predecessors.) In Kansas City, there are 6,500 linear miles of lanes just in the city street system—so not including county, state and federal roadways. This is the equivalent of driving from New York to San Francisco and back, with a bonus trip to Portland, Maine. According to the Kansas City public works department, to maintain and replace existing roads it needs ten times more money each year than it can ask for.
