Plans for its construction were approved by the Danish Parliament on 1 June 2007. Preferred bidders were announced during November 2010. The total cost was estimated at 15 billion kroner but had risen to 21.3 billion kroner ($3.39 billion) when the contractors were announced in late 2010. It is a fully automated line, using driverless trains and capable of routine 24/7 operations. Italian rolling stock manufacturer AnsaldoBreda provides the trains for the new line, and the stations are intentionally similar to the Copenhagen Metro's existing stations. The transit agency Movia has projected that up to 34 million passengers eventually switch from buses to using the Metro during each year.
