The Kamener Kreuz was formerly a full cloverleaf interchange near Dortmund in North Rhine-Westphalia Germany where the Autobahnen A1 and A2 meet. It lies between the towns of Kamen and Bergkamen in the west and the city of Hamm and the municipality Bönen in the east. The Kamener Kreuz, opened in 1937, was the second interchange between two Reichsautobahnen, the first one being the Schkeuditzer Kreuz. It is used by 160,000 vehicles per day.
