Kronprinsesse Marys Bro

Kronprinsesse Marys Bro is a four-lane highway bridge made of steel and concrete that spans across Roskilde Fjord. It provides enough height for maritime traffic to pass underneath and connects two sides of the region with a continuous roadway.

The bridge was built in the 2010s to improve traffic flow across Roskilde Fjord and provide an alternative to the older crossing in the area. Its construction was part of Denmark's effort to modernize the transport network connecting the regions on either side.

The bridge bears the name of Crown Princess Mary and links Frederikssund with the Hornsherred Peninsula as part of the daily commute for thousands of travelers. It has become an integral part of how people experience and move through this part of Zealand.

The bridge carries heavy traffic during peak hours as a main commuter route, so travel times can be longer in the morning and evening. Plan your crossing for quieter times of day if your schedule allows, as congestion is common during rush hours.

The bridge was built using 492 prefabricated deck segments that were manufactured abroad and then assembled on site. This industrial construction method allowed the project to progress more efficiently than building everything directly on the fjord.
