The '''A45''' is a highway motorway in [[Germany]], connecting [[Dortmund]] in the west with [[Aschaffenburg]] in the southwest. It is colloquially known by its byname Sauerlandlinie, which derives from the Sauerland, the landscape which said autobahn is running through between the cities of [[Hagen]] and [[Siegen]]. Many people think of it as the ''Queen of autobahns'', for it's beautiful landscape and for the fact that no autobahn runs over a greater number of bridges.
It's the main connection for traffic coming from the North ([[A1 (Germany)|A1]]) towards [[Frankfurt]], though people could also consider traveling the [[A3 (Germany)|A3]], which most likely will end in traffic jams around [[Cologne]].
