Transport in Denmark
Transport in Denmark is developed and modern. The motorway network now covers 1,111 km while the railway network totals 2,667 km of operational track. The Great Belt Fixed Link (opened in 1997) connecting the islands of Zealand and Funen and the New Little Belt Bridge (opened in 1970) connecting Funen and Jutland have improved the traffic flow across the country on both motorways and rail. The airports of Copenhagen and Billund provide a variety of domestic and international connections while ferries provide services to the Faroe Islands, Greenland, Iceland, Germany, Sweden, Norway and the United Kingdom as well as routes to the Danish islands.
In 2011, a total of approximately 28m passengers used Danish airports.
Copenhagen Airport is the largest airport in Scandinavia, handling approximately 23m passengers per year (2011). It is located at Kastrup, 8 km south-east of central Copenhagen. It is connected by train to Copenhagen Central Station and beyond as well as to Malmö and other towns in Sweden.
For the west of the country, the major airport is Billund (2.7m passengers in 2011) although both Aalborg (1.4m passengers in 2011) and Aarhus (591.000 passengers in 2011) have smaller airports with regular connections to Copenhagen.
List of airports 
Denmark's main airports are:
- Copenhagen Airport (CPH), Scandinavia's busiest passenger airport located at Kastrup to the south-east of Copenhagen city and handling over 21 million passengers a year.

Bicycling in Denmark is a common and popular recreational and utilitarian activity. Bicycling infrastructure is a dominant feature of both city and countryside infrastructure with bicycle paths and bicycle ways in many places and an extensive network of bicycle routes extending more than 12,000 kilometres (7,500 mi) nationwide (in comparison Denmark's coastline is 7,314 kilometres (4,545 mi)). As a unique thing, Denmark has a VIN-system for bicycles which is mandatory by law. Often bicycling and bicycle-culture in Denmark is compared to the Netherlands as a bicycle-nation.
