The Project, a Private Public Partnership (PPP) model, consists of the 25 km long newly built motorway M51 between Kliplev and Sonderborg, crossing Denmark east-west and connecting to the existing E45 at Kliplev. The 30-year concession project involves the funding, design, construction, operation and maintenance of 25 km of new dual carriageway, including approximately 60 bridges of which 19 are longer over- and underpasses.
