Deep in the primary rock beneath AlbaNova at Roslagstull in Stockholm, Vejdekke is constructing something that at present most closely resembles an underground cathedral with a height of eleven metres from floor to ceiling. Once everything is finished in six years' time, and a million cubic metres of blasted rock have been removed, there will be more than four kilometres of road tunnel in the Norra Lnken (northern link) motorway here. The tunnel driving itself is expected to be completed next year.
