The E20 past Mariestad is to be remodelled as a country road with central barrier on a section about 17 km long. There will be 2+2 traffic lanes, separated by a central barrier.
The Swedish Transport Administration decided how work on the E20 past Mariestad was to proceed in December 2016. Work on the choice of location resulted in the blue corridor, i.e. the corridor that mainly follows the present route.
Since summer 2017, work has been proceeding on the road plan Consultation document, design of location alternative. With effect from the present stage, the project will be divided into two parts, Hindsberg- Muggebo and Muggebo-Tjos. This means that two road plans will be produced.
