The project involved demolishing the Bispelokket intersection, renovating adjacent parts of Nylandsveien bridge and developing new city streets. Dronning Eufemias gate has been described as ‘the avenue through Bjørvika’. The street has a total width of 43.2 metres, and contains a tramway, general traffic lane, bus lane and cycle lane in each direction, as well as two extremely wide pavements. Because of extremely difficult ground conditions, with ground prone to settlement, Dronning Eufemias gate was constructed on a concrete slab foundation (around 30,000 m2 in area), with piles down to rock (around 1000 piles, with a total length of around 40 kilometres). All the streets have been surfaced to a high standard, and have been extensively planted. A total of around 600 trees have been planted on this contract. As land that has been reclaimed from the sea and infilled with material from the mediaeval period, Bjørvika is extremely interesting from an archaeological aspect. Preliminary archaeological surveys were performed before the start of construction work, and some excavation work was performed during the construction period. While construction of the road system was underway, other development work was also taking place, which meant that a number of modifications were needed in order to interface with future developments in the new district. These complex interface issues required close coordination work between a large number of different parties. Bjørvika Stage 2 was a highly interdisciplinary project, and one of the first transport projects to use 3D as a central tool in the design and execution.
