Oskara Kalpaka Bridge in Karosta Infrastructure

The bridge named after Oskaras Kalpaka is Liepāja's gateway to the Karosta and is located at the meeting point of Oskaras Kalpaka and Atmodas Street - across the Karosta Canal.

The unique swing bridge was opened on 19 August 1906. The bridge was blown up during World War I, but was rebuilt after the war. The bridge was rebuilt again after it was damaged by the steamship Narne in 1926, but it also suffered during World War II when the invading Soviet army shelled the port of Liepaja. Until the restoration of independence of the Republic of Latvia, the Karosta was a closed area of Liepaja, inaccessible even to the inhabitants of Liepaja. The entire Karosta was a military facility, so traffic over the bridge was controlled around the clock by guard posts. Crossing the bridge to the Karosta was only possible with special permits for a few hours a day, the rest of the time the bridge was open to the traffic of Soviet warships. Throughout the years of occupation, the name of the bridge was "Red Army Bridge". In the summer of 2006, the Georgian-flagged tanker "Anna" flew into the northern abutment of the bridge, and after reconstruction, the Oskars Kalpaka Bridge was officially opened in August 2009. 

The bridge weighs 300 tonnes and consists of two parts (North and South sides) made of two identical cantilevers. The bridge carriageway is 7.3 metres wide and its deck is made of wooden planks. The total length of the bridge is 133 metres with a span of 27.55 metres + 77.9 metres + 27.55 metres. The height of the bridge above water level is 8.32 metres. The bridge is cut at the appointed times and, in accordance with the Port Safety Regulations, a vessel shall only commence traffic when the bridge is open to vessel traffic and it is safe to enter or leave the Karosta Channel. The Oskars Kalpaka Bridge is turned back to vessel traffic 5 times a day. The bridge is not cut at the specified times if the wind speed exceeds 10 m/s or if no manoeuvres are planned.
