We are together with our client, Trafikverket, working on two areas of the E4 Stockholm Bypass Project. One is located on the north side of Lovön and the other one on the south side.
We are preparing for tunneling of the main tunnels by building work paths that will be used for transport of work machines and the removal of rock piles both on the south and north areas on Lovön. The tunnel work starts by releasing the rock (a so-called forecasting) and then begins the grouting and blasting of (tunneling) of the work tunnels which allows us to effectively go deeper in the mountain.
The tunnels are being built in downward direction so it can reach the level of the main tunnels, which will be 60 meters below ground level.
In June 2018, the main tunnel on the north side of Lovön was reached and to be able to continue our tunneling work we are now preparing all our systems to support the excavation for the main tunnel.
In parallel, other work is being done such as assembly of rock crushers, assembly of temporary ports and construction of the conveyor belts that reaches up to a length of 2 km. The conveyor belts are used for transporting crushed rock piles from the tunnels to our temporary ports, were the rocks get unloaded on ferries to be shipped of to specific ports.
In January 2018, the construction work of Road Edeby on south of Lovön started. To read more, click here.
