Fuel Conservation On The Old Highway System

Summary

The original US highway system, a series of smaller highways assembled into a natinoal highway system prior to the Eisenhower Interstate System, still connects the majority of large- and moderately-sized cities, with well-maintained roads, but with lower speed-limits, curves and hills, and fewer ways to pass other drivers. The lower speed limits will provide gasoline conservation, while opening up smaller communities to the travellers they lost with the Interstate, and leaving the Interstate System to industrial transporation and high-speed travel.

Introduction

My family and I travel from to Milwaukee and Sheboygan many times a year for family, and, of course, we've become quite familiar with the Eisenhower Interstate System. As a military man, Eisenhower served along Europe's well-developed roadways during WWII, traveled across the US' poor roads by car, and his experience followed him to his presidency. Eisenhower believed the US would benefit from a similar infrastructure, connecting our major cities with high-speed, low-access roadways to promote travel and commerce. North Dakota's stretch of I-94 was the first completed, and the system expanded from there. We drive on I-94 from Fargo, through Minneapolis, to Tomah, Wisconsin, where it connects with I-90 and continues to Milwaukee. On other occasions, when we've felt we had more time to spend, we've traveled along sections of Old US 10 in both Minnesota and Wisconsin, and we've made some discoveries that might otherwise seem counterintuitive. The slower speed limits and landscape should slow down our driving time, the hills and curves and stop-signs should severely impact fuel efficiency, and it must be difficult to find gas stations and restaurants. In fact, much of the above are untrue, and the benefits of taking a non-Interstate route outweigh the percieved benefits of the straighter, faster route.

The Non-Interstate Highway System

The US Interstate system was devised as a high-speed conduit between large cities, connecting one end of the country to the other, for transportation and commerce. The previous system of roads was hardly integrated on a national level, and large portions of interstate roads were dirt or gravel and not suitable for high speed travel. The curvy highways that connection numerous small communities were bypassed, straighter lines were drawn through far fewer communities and away from obstacles, to allow vehicles to travel with minimal reasons to change speed, stop, or watch for obstacles like pedestrians or parked cars.

Current State of Non-Interstate Highways

While many still have the mindset that non-interstate roads are of poor quality and are minimally cared for, the truth is much different. The US Department of Transportation has taken great efforts of provide a national highway system that passes within 8km of 90% of US residents, maintained and updated to higher standards to allow vehicles similar driving experience to the interstate, once those cards and trucks leave the interstate roads. The high fuel prices lamented by most usually come with the caveat, "well, it's all the taxes on the gas that get's you." Those taxes on the state and local levels have not evaporated; they hve gone to supporting the roads used most by the citizens who pay those fuel taxes. Stretches of rural NHS roads may have degraded surfaces, but this is no different than interstate roads to the similar regions.
