Palmburg Bridge, Transport bridge in Kaliningrad, Russia

Palmburg Bridge was a steel and concrete structure that crossed the Pregolya River and connected different parts of Kaliningrad. It was designed for vehicle traffic and featured the straightforward engineering style typical of 1930s construction.

Built in 1938, the bridge carried the southern bypass over the Old and New Pregolya. On the night of 29–30 January 1945, General Otto Lasch ordered it blown up; the inserts dropped into the river and reduced the fairway depth, halting the Soviet advance until 6 April 1945. A 1970s restoration reopened two lanes, and the second bridge was rebuilt in 2016.

The name Palmburg ("palm town") came from a nearby agricultural estate whose owner grew exotic plants, including palms, in greenhouses. After East Prussia was transferred to the Soviet Union, Russian speakers began calling it the Berlin Bridge, and the old name fell out of use.

The bridge remained partially operational with two lanes until 2012, when plans for a replacement crossing began. Today visitors can observe the remains from the riverbanks or by walking along the Pregolya if local access allows.

The central span collapsed into the Pregolya River during World War II, creating an underwater obstacle that affected military operations in the area. The remnants still lie beneath or partially above the water surface today.
