Peab has been commissioned to expand E20 at Mariestad and put in a central barrier. The customer is the Swedish Transport Administration and the contract is worth SEK 848 million. The project involves rebuilding E20 from the current motorway section at Götene to west of the Haggården interchange at Mariestad.

The new 20 kilometer stretch will be a 2+2 lane road with a central barrier and an overpass at of the Lugnås interchange. Bearing capacity is low in places in the existing road and it is not fully dimensioned for heavy vehicles. There have also been problems with frost heaving, which has led to cracks in the road.

In addition to rebuilding this stretch of the road, the project also includes building thirteen concrete bridges and a tubular bridge. When completed, the road will be signposted as a clearway and have a speed limit of 100 kilometers per hour. The existing E20 will be narrowed and retained as a local road.

The project is a turnkey contract that will start in the summer of 2024 and is expected to be handed over in 2028. The project will be order registered in the second quarter of 2024.
