The Bergsøysund Bridge (Norwegian: Bergsøysundbrua) is a pontoon bridge that crosses the Bergsøysundet strait between the islands of Aspøya (in Tingvoll) and Bergsøya (in Gjemnes) in Møre og Romsdal county, Norway.

It is part of the Krifast system, the town of Kristiansund's road connection to the mainland.

Floating bridge/pontoon bridge construction has a long history in military and civilian applications on every continent except Antarctica.

According to the engineers who designed this bridge, it was designed using recent American technology for floating bridges, combined with Norwegian technology for offshore platforms.

This design afforded: 1) an elevated roadway that reduced traffic hazards in storms, 2) a reduction in corrosion of the bridge deck, and 3) improved passage of water beneath the bridge thereby supporting native species.
