According to TV2, the Storebæltsbroen Bridge management announced that the bridge will experience a series of temporary closures during the next week due to necessary maintenance work related to repairing what are known as "expansion joints," which are essential parts of its engineering structure, according to a press release issued by the bridge management and published by TV2.
Nighttime maintenance work with traffic diversion
The bridge management stated on its website that maintenance work will be carried out during nighttime hours on weekdays, during which time two-way traffic will be implemented. The bridge will also be closed for short periods in the evening and early morning hours to safely reroute traffic.
Schedule of temporary closures
The administration explained that The closures will only last for one week. According to the following table (assuming Sunday, October 5, 2025):
- Monday: From 19:00 to 19:45.
- Tuesdays, Wednesdays and Thursdays: from 05:00 to 05:45, and from 19:00 to 19:45.
- Friday: From 05:00 to 05:45.
Maintenance work for expansion joints
The statement indicated that the maintenance work focuses on repairing the expansion joints, crucial components that allow the bridge to adapt to temperature changes, expanding in hot weather and contracting in cold. Kim Agersø Nielsen, technical director at Sund & Bælt, commented on the statement:
«The bridge expands with heat and contracts with cold, and expansion joints are essential to its structure because they allow this natural movement with changing temperatures. After many years of use, it is time to repair a number of these joints to ensure the bridge continues to last for many years to come.».
Limited impact but necessary
According to the bridge management, these short-term closures are necessary to ensure the safety of maintenance work and the safe implementation of traffic diversions. They also emphasized that the maintenance work aims not only for immediate repairs but also to ensure the bridge's long-term sustainability and the safe and stable flow of traffic.
What is the Storebælt (Great Belt) bridge?
The Storebælt Bridge is one of the most important engineering structures in Denmark and is one of the longest suspension bridges in the world. This bridge connects the islands of Zealand (or Zealand in Danish) Sjælland and Fyn - which includes Odense, the third largest Danish city after Copenhagen and Aarhus - and it forms a pivotal part of the national road and rail network. It also connects the eastern and western parts of the country directly without the need for ferries and sea vessels as was the case in the past.
Bridge components
The Storebælt bridge consists of two main parts and a tunnel:
- The East Bridge (Storebæltsbroens Østbro): It is a suspension bridge with a total length of approximately 6.8 kilometers, extending over the deep waterway through which ships pass. It includes huge pillars with a height of about 254 meters, making it one of the highest suspension bridges in the world, and it connects the island of Zealand with the small island of Sprogø.
- West Bridge (Storebæltsbroens Vestbro):
It is a relatively low bridge, approximately 6.6 kilometers long, connecting the island of Fyn to the island of Sprogø, and is used for both cars and trains. - The Eastern Tunnel (Østtunnelen): Used for rail transport between Zealand and Spruce, it runs under the sea.
Opening date
Construction of the bridge began in the late 1980s and took about 10 years to complete. The railway section opened in 1997, while the road section opened in 1998. Since then, the bridge has been a vital factor in facilitating movement between eastern and western Denmark.
Economic and strategic importance
- The bridge significantly reduces travel time between Copenhagen and Odense, and is a key route linking Sweden, Denmark and Germany via the European E20 road network.
- It plays a pivotal role in road and rail freight traffic, and is used daily by thousands of cars and trains.
- It also represents a remarkable engineering achievement, as it has helped reduce reliance on ferries and supported economic and geographical integration within Denmark.
Fees and maintenance
Crossing the bridge is not free; cars and trucks are charged a toll. These revenues are used to fund ongoing maintenance and recoup construction costs. The bridge management also carries out regular maintenance work on expansion joints, roads, cables, and the structural system to ensure its long-term safety and efficiency.
