Bundesautobahn 7

is the longest German Autobahn at 935 km (581 mi) . It splits the country almost evenly from north to south. In the north, it starts at the border to Denmark as an extension of the Danish E45. In the south, it ends 18 km shy of the Austrian border. This gap is in the process of being closed, including the construction of two tunnels of 630 and 1245 m length.
