About Crown Princess Mary’s Bridge

The Frederikssund Connection is an expressway that crosses Roskilde Fjord via a high bridge called Crown Princess Mary’s Bridge, just south of Frederikssund.

The new connection across Roskilde Fjord

For years, long queues have made the trip through Frederikssund across Roskilde Fjord via Crown Prince Frederik’s Bridge time-consuming and tiresome for both local inhabitants and businesses in the area. In the rush hour, in particular, heavy traffic has caused people to waste time on a daily basis.

To relieve the pressure on Crown Prince's Frederik’s Bridge and ease daily life for the municipality’s inhabitants and businesses, Frederikssund Municipality concluded an agreement with the government in 2012 to construct a new connection across the fjord.

By the autumn of 2019, the new connection with a bridge and an expressway will be ready to open for traffic. The official inauguration will take place on 28 September 2019.

Fjordlandsvej and Crown Princess Mary's Bridge

Crown Princess Mary's Bridge is part of the Frederikssund Connection, an almost 10-km-long expressway that has been named Fjordlandsvej. Around 1.4 km of Fjordlandsvej is made up of Crown Princess Mary's Bridge, a high bridge that allows ships to pass underneath.

Heavy traffic must use Crown Princess Mary's Bridge.

After the inauguration, heavy lorry traffic will bypass the city and cross the fjord via Crown Princess Mary's Bridge. The Construction Act governing the new fjord crossing stipulates that lorries with or without trailers and articulated lorries over 3,500 kg must use the new bridge.

Other road users can choose between Crown Princess Mary's Bridge and Crown Prince Frederik’s Bridge when crossing Roskilde Fjord.

Saving time

We expect that passenger vehicles will be distributed evenly between the two bridges, so that traffic will move more easily and road users waste less time. For some drivers, crossing on Crown Prince Frederik’s Bridge will be the logical option, whereas other road users will find it more convenient to use Crown Princess Mary's Bridge.

By using Crown Princess Mary's Bridge, road users from the southern part of Hornsherred peninsula will save up to 30 minutes on their trip to Copenhagen in the morning rush hour. This is partly because the trip is shorter, and partly because the trip from Hornsherred across Crown Prince Frederik’s Bridge can take up to 15 minutes longer during the rush hour than outside the rush hour.

In 2017, approximately 20,300 cars crossed Crown Prince Frederik’s Bridge on a daily basis, almost as many as crossed the Oresund Bridge between Copenhagen and Malmö in Sweeden.
