Korketrekkeren

Korketrekkeren is a road bridge in Langangen, Porsgrunn, with a distinctive spiral design that rises steeply through the landscape. The corkscrew shape allows vehicles to gain significant elevation while crossing a valley, making a direct connection possible where a conventional bridge would not fit.

The bridge was built to solve a difficult terrain challenge in the region and became one of Norway's most notable road engineering solutions. Its spiral design emerged from the need to cross a steep valley efficiently, representing an innovative approach to road construction challenges.

The bridge's construction represents Norwegian engineering practices, incorporating local architectural elements into the transportation infrastructure of Porsgrunn municipality.

Driving across the bridge requires careful attention due to its tight curves and steep sections. The journey is best experienced during daylight hours and in clear weather, allowing you to fully appreciate the structure while navigating safely.

The name Korketrekkeren literally means corkscrew, named after its unusual shape that rises in a complete spiral. This design was bold engineering for its era and makes the bridge a remarkable example of how engineers creatively overcame a landscape obstacle.
