Kronprinsesse Marys Bro

The steel and concrete structure stretches 1.36 kilometers across Roskilde Fjord, featuring a 19.7-meter width and 22-meter vertical clearance for maritime traffic.

The Danish Road Directorate awarded the construction contract in September 2016 to a joint venture of BESIX, Rizzani de Eccher, and Acciona Infraestructuras companies.

The bridge bears the name of Crown Princess Mary, connecting the town of Frederikssund with the Hornsherred Peninsula as part of Denmark's Primary Route 53.

The four-lane dual carriageway reduces traffic congestion on the older Kronprins Frederiks Bro, serving over 30 percent more commuters than previous infrastructure.

Construction involved 492 prefabricated deck segments manufactured in Poland and V-shaped pylons secured into limestone bedrock beneath the fjord.
