Norssalmi Bridge, Box girder road bridge in Kotka, Finland.
Norssalmi Bridge is a concrete road structure that spans 225 meters and connects different sections of Kotka using box girder technology throughout. The bridge provides a 13-meter-wide roadway that accommodates both vehicle and pedestrian traffic across the waterway.
The bridge opened in December 1983 and marked an important milestone in transportation infrastructure development for the Kotka region. This completed a major connection project that improved travel between previously separate areas of the city.
The bridge links residential neighborhoods with industrial areas and plays a practical role in supporting maritime activities in this Finnish coastal city. It serves as a daily connection for people moving between different parts of Kotka.
The bridge is open year-round for vehicle traffic and provides a stable crossing over the water with good access from both sides. Pedestrians should use marked paths and be aware of normal traffic conditions when crossing.
The bridge uses hollow box girder beams that minimize weight while maintaining maximum load capacity at the same time. This engineering approach allowed builders to create a strong structure without excess materials.
