The government's decision enables Trafikverket to continue planning and begin preparatory work, though a construction start decision is still pending before major contracts and road production can commence. The road will run along the edges of the reserves, with parts in tunnels under sensitive areas to preserve natural values. Compensatory measures include fauna bridges designed with greenery and high side panels to shield wildlife from car lights.
To protect bats, 13 of Sweden's 19 bat species have been identified along the route. Trafikverket's environmental specialists conducted inventories to map bat colonies. Project manager Alexandra Stassais Söderblom said sensor-controlled lighting with infrared light will be used to minimize disturbance.
Trafikverket's planning principle is to minimize impact on nature and people.
