Lovön Samverkan AB In August of 2016, the contract for Trafikverket´s project, E4 The Stockholm Bypass- Förbifart Stockholm was signed by our two Italian entrepreneurs Vianini Lavori S.p.a and CMC to build the two main tunnels on the north and south part of Lovön in Ekerö County. In context of wining the contract with Trafikverket , the two entrepreneurs formed the Swedish joint venture company Lovön Samverkan AB, LSAB. LSAB will on behalf of Trafikverket build the two main tunnels, two temporary ports, ramp tunnels and two working tunnels. The Stockholm bypass will take approximately 10 years to finish and is considered to be the largest infrastructure project in Sweden in modern times . http://www.trafikverket.se/en/startpage/projects/Road-construction-projects/the-stockholm-bypass/ Publicerad: 2017-05-03
