Tromøy Bridge

Tromøy Bridge connects the island of Tromøya to the mainland across the Tromøysundet strait and stretches about 400 meters in length. The structure is built from concrete and steel, designed to allow seagoing vessels to pass underneath.

Planning for the structure began in 1938 under the leadership of Christian Stray, but completion took more than two decades until 1961. The opening ceremony was conducted by Transport Minister Trygve Bratteli.

The bridge has become a symbol of connection between the island and the city, shaping daily life for those who cross it regularly. It transformed Tromøya from an isolated place into an accessible residential area and destination for visitors.

The bridge serves as a key road connection with thousands of vehicles crossing daily and provides ample space for maritime traffic below. Visitors can walk or drive across and enjoy views of the strait and surrounding landscape along the way.

The structure is composed of twelve separate spans, with the main span measuring about 240 meters and standing out distinctly from the other sections. This design makes the bridge a remarkable example of Norwegian infrastructure engineering from the 20th century.
