"...The best possible way to bring the German people back into work is to set German economic life once more in motion through great monumental works... This is not merely the hour in which we begin the building of the greatest network of roads in the world, this hour is at the same time a milestone on the road towards the building up of the community of the German people. "

-- Adolf Hitler
Perhaps best known throughout the world for its superior engineering and open stretches without a speed limit, the Autobahn was Hitler's invention from his dreams about an interstate highway system. Over 2000 km were built by 1938 and today approximately 11.000 km cover Germany. True to stereotypes about German engineering and maintenance, road designs are solid without a single pothole, with 4% or lesser grades, long acceleration and deceleration lanes, gentle curves, and free-resistant surfaces. Just as Hitler insisted on having buildings and other infrastructure that would last 1000 years, the engineers of the Autobahn design things right the first time and perform critical inspection and thorough maintenance to keep the best highway system in the world at peak operational performance.
