Smögenbron, Vehicle bridge in Sotenäs Municipality, Sweden.

The Smögenbron is a concrete bridge just over 400 metres long and 35 metres high, linking the island of Smögen to Kungshamn on the mainland. Construction began on 23 September 1968 and the bridge opened on 25 December 1970, replacing the car ferry that had served the island since 1958.

Construction of the Smögenbron began on 23 September 1968 and the bridge opened on 25 December 1970, replacing the car ferry that had served the island since 1958. In 2024 Trafikverket fitted taller railings to reduce the risk of people jumping; in certain wind directions residents nearby were then troubled by high-frequency noise from the railing, whose shape had unintentionally created an aeolian harp.

The bridge connects Smögen to the mainland, allowing visitors to reach a harbor town where traditional red and white wooden houses line the waterfront. Fishing remains integral to local life and shapes how the place looks and functions daily.

The bridge deck is about 35 metres above the water, so crossing it on foot gives a wide view over the harbour on the Smögen side and the mainland at Kungshamn. Since 2024 the railings have been raised to reduce the risk of jumps; in certain wind directions residents nearby hear a high-frequency tone from them, an unintended aeolian harp. Pedestrians share the crossing with road traffic.

The design was specifically engineered to allow ships of varying heights to pass underneath while road traffic continues above. This dual function makes the structure an interesting example of practical engineering.
