New bridge on the E22 – a step-by-step guide

On April 5, 8.00 p.m. (20.00), the E22 will be closed. Work will begin immediately to remove the asphalt, using a machine called an asphalt miller.

Asphalt milling and excavation of clay

The advantage of milling the asphalt in this way is that it can be recycled, and 2 500 square metres of asphalt will be removed. The work will take around eight hours, and then the material will be removed from the site and taken for recycling. 

Once the asphalt has been removed, the major work of excavation can begin. To make space for the new bridge, 17 000 cubic metres of clay must be excavated. most of which can also be recycled. Some will need to be transported to the municipal depot at Rögle.

Demolition of the old bridge

Parallel with the excavation work, the old bridge will be demolished. The concrete and its metal reinforcement will be broken up by a machine called a crusher and a pneumatic drill. This is an especially noisy phase, but we will be doing everything we can to dampen the noise. The work to break up and remove the asphalt, excavate the clay and demolish the old bridge will take place between Friday and Sunday. The tramway team will be working 24 hours a day throughout the period. The concrete and the metal reinforcement from the old bridge will not be transported away directly, but will be stored on site until it can be sorted.

Preparation of the ground

Once the clay has been removed, and the old bridge demolished, the ground will be prepared for the launching of the new bridge. The equipment that will allow the bridge to be rolled into place – launching plates and beams – will be assembled and put in place.

Concrete slabs, beams, and lifting beams

28 specially made concrete slabs will be placed on top of the compacted gravel bed. These prefabricated slabs will be ten metres long. Beams, the same length as the slabs, will be placed on top. 12 large lifting beams will be used to lift the bridge. The lifting beams, which together weigh 83 tonnes, will be assembled through the legs of the bridge. 

Movement of bridge starts April 8

On Sunday April 8, everything will be in place and the bridge will be launched. This means, quite simply, that the bridge is lifted and rolled into position. Not an easy process for a bridge that weighs 5 000 tonnes, is 8 metres high, over 40 metres long and 40 metres wide. 

The bridge will be lifted using twelve jacks, positioned at lifting points. Eight strand jacks will be used to get the bridge in motion. On Monday and Tuesday, the bridge will be rolled into position, using a system that ensures that all movement is smooth and stable. Already on the Tuesday, the bridge will be in position and all launching material, jacks and beams, removed.

Crushed rock as filling around the new bridge

Walls of supporting concrete will be built around the bridge, and then the most time consuming part begins. From Tuesday April 10 until Saturday April 14, 9 000 tonnes of crushed rock will be used to fill up the ground around the bridge. Reused concrete cannot be used as filling for a road – crushed rock designed for highway filling is needed, otherwise there is a risk of subsidence in the road. 

Final stage – asphalt, crash barriers, road markings

On Sunday April 15, the final part of the bridge launch will take place. Asphalt will be laid, crash barriers will be built, white road markings will be painted, and the final inspection of the bridge will be made before opening. On April 19 the new widened bridge will be opened, Bridge Number Bro 100-592-1. 

Pedestrian and cycle path on Sölvegatan under the E22 closed until May 21

The pedestrian and cycle path under the E22 will remain closed until May 21. During this time, we will be installing pipes and completing excavation work.
