The debt incurred by the toll company was paid off by August 2013. The company had by the collected NOK 1,400 million, twice the debt incurred. The remainder was used for interest and to operate the toll plaza, which cost NOK 14 million in 2012. In March 2012 the Public Roads Administration, based on the plans to build a second tube, announced a prolonging of the toll period, initially with another three years. The agency stated that advanced tolls on a new tube would allow for a lower total toll collection, as interest payments would be lowered. In addition the tolls would stimulate for less traffic through the tunnel, which the agency wanted to reduce until a second tube opens. Should the second tube not be built, the tolls will be used for other projects in the area.
