Denmark: Langebro – will it soon no longer be possible to drive through Copenhagen?

A six-week public consultation on the future of the Langebro has been underway since 9 September. The city then intends to decide whether the bridge should remain open to shipping. The decision is to be taken into account in the budget negotiations in spring 2027.

Costs of at least 56 million euros

The bascule sections of the bridge, which opened in 1954 and is one of the Danish capital’s landmarks, are in need of refurbishment. According to the city, restoring the bridge so that it can continue to open fully would cost between 400 and 417 million Danish kroner (around 56 million euros), plus 44 million kroner for associated works.

The construction period would be around three years, between 2029 and 2034. The local authority estimates that a solution which cannot be opened again would cost a total of around 207 to 257 million kroner and take about one and a half years to build.

Seven metres beneath the closed bridge

When closed, the Langebro bridge has a clearance height of around seven metres above the normal water level. This is sufficient for many smaller vessels and pleasure craft, but not for sailing yachts and larger ships. The city records around 100 instances of the Langebro being opened each year, mainly for excursion boats, but also for private sailing yachts, houseboats and work vessels. The number of passages, whether the bridge is open or closed, is reported to be 16,000.

From mid-2028 onwards, it will no longer be possible to order openings due to the poor condition of the flaps. This means the issue is becoming a concrete one at an early stage for district planning in Copenhagen. The city had already recently new rules for the port area introduced. The extent to which work on a bascule bridge can shape the passage is also demonstrated by the Closure of the King Christian X Bridge in Sønderborg. Details of the consultation are published by the City of Copenhagen.

Book recommendation

Cruising Guide: Denmark 2 covers the Danish Baltic Sea from southern Funen to Bornholm, with a particular focus on Zealand, including Copenhagen and the Öresund. The volume explains nautical features, harbour approaches and moorings with the aid of maps and photographs. For crews planning a detour to Copenhagen Harbour, it thus provides the necessary orientation of the area, going beyond the current debate on bridges.

In your view, what significance does a Langebro that can still be opened have for sailing trips and life in Copenhagen harbour?
