Autobahn – A Guide for my Foreign Friends

Going fast is fun! Legend has it, Autobahns have no speed limit. A few road signs tell your legal moves from speeding and when to better get out of the way.



Autobahns are controlled-access highways. The photo above reveals some design details that make safe, fast travel possible. Rather than pouring out asphalt and see where it sticks, there's a bridge built across a rather shallow valley, the hill in front has been cut into to lay the road through. Built in seven layers, the road surface is flat, smooth and provides grip, drainage puts away with rain, side rails keep you on track if necessary. Autobahns are built for high throughput and high speed. That makes them expensive and different from roads in much bigger countries that must stretch across large distances at economic expense.
