Bispelokket gradually opened between 1966 and 1968, and was visited by at the most 140,000 vehicles a day until Bjørvikatunnelen was introduced as a complete tunnel system in 2010 and the amount declined to 40,000.[1] Bispelokket ceased to function as a roundabout on October 28, 2011, at 10 pm. The physical demolition was launched by the Norwegian prime minister Jens Stoltenberg, November 4, 2011, at 1:46 pm.[2] As a complex road intersection, Bispelokket was not recognized as an aesthetical suitable landmark in the cityline of Oslo.
Sinsenkrysset is from October 31 the most visited Norwegian road intersection by 100,000 vehicles a day.
Demolition
As a part of the Fjord Cityurban renewal project, Bispelokket (including all its ramps and the Nylandsvegen bridge) was demolished in 2012 to make way for the redevelopment of the Bjørvika waterfront into a business and residential area.
