Construction started in January 2008. To pass over Strømmen, a fourth Nygård Bridge was built for cars, and the oldest was upgraded and used by the light rail line. In several places the road needed to be dug up to remove pipes and cables. In November 2009, Gulating Court of Appeal ruled that the power company BKK had to pay 80 million NOK for the moving of power lines, and could not charge the costs to the project. By June 2008, the first tracks had been laid.
