The entire project cost NOK 1,814 million. The costs were distributed to NOK 476 million for the Bømlafjord Tunnel, NOK 433 million for the Stord Bridge, NOK 336 million for the Bømla Bridge, NOK 46 million for the Spissøy Bridge, NOK 36 million for the Digernes Tunnel, NOK 325 million for roadways and NOK 172 for administration and common costs. The investment cost was split between state grants and NOK 1,036 million in debt taken up by the toll company. When the project was passed by Parliament it had a budget of NOK 1,260 million. The Office of the Auditor General of Norway criticized the Western Norway Public Roads Administration in 2001 for a total cost overrun of NOK 900 million in three projects, the Triangle Link, the Lærdal Tunnel and parts of National Road 555. The majority of the cost overruns were tied to the Triangle Link. As a consequence, Minister of Transport Torild Skogsholm stated that future large road investments would have an external quality assurance before being presented to Parliament.
