The Oberbaumbrücke is a two-level bridge over the River Spree in Berlin. It unites the Berlin (Ortsteil) districts of Friedrichshain and Kreuzberg since 2001. The bridge was built of wood in 1724 and was the longest bridge in Berlin for decades.
Before the current construction, there was a wooden bridge located further west along the course of the Spree, at the then customs post. From 1961 to 1989 it was a pedestrian "border crossing" between East and West Berlin.
