BUNDESAUTOBAHN 31

is a German Autobahn that connects the coast of the North Sea near Emden to the Ruhr area. It is also known as 'Emsland-Autobahn' or 'East Frisian Skewer'.
It was completed in December 2004. Construction was in part made possible by a unique method of financing: individuals, companies, towns, counties and the Netherlands donated money to accelerate the project.
