A Widerlager Strassensperre is a type of German-engineered road block or barrier structure, typically consisting of reinforced concrete supports designed to hold up heavy beams or logs to block roads. The term 'Widerlager' refers to the supporting abutment or bearing structure, while 'Strassensperre' means road barrier. These defensive installations were commonly used during WWII and the Cold War to control or block access to strategic areas.
Norway, due to its proximity to the Soviet Union during the Cold War, built many such military bunkers and barriers as part of its defensive infrastructure.
