The Tour de France riders are expected to complete the 13 kilometres in Copenhagen in less than 20 minutes. However, even though many Copenhageners love their bicycle and travel a distance that is equivalent to 330 Tour de France races or 1,390,000 km on a daily basis, many people also choose the metro when travelling through the city.
The Copenhagen Metro has run since 2002, and COWI managed the overall design of almost 39 of the metro stations and the 36 km underground tunnels and tracks. In connection with the construction of the underground city ring, 3.1 million tons of waste was removed.
Below the historical city centre, technical challenges arose, related to shallow tunnelling under old buildings. To prevent damages, the buildings were monitored by sensors, and, in some cases, COWI established a system with pipes under the construction, which made it possible to lift up the buildings.
COWI also developed strategies for the groundwater control work, which made it possible to construct the metro without a large-scale lowering of the groundwater which would have been critical to the Copenhagen historic city centre.
Last year, more than 73 million passengers used the Copenhagen Metro which has twice been awarded the world's best metro. The open squares around most metro stations are designed for urban life and for parking bicycles, of course!
