The Kliplev Sønderborg Motorway: DSI contributes to Denmark’s first PPP Project

An approx. 25km long highway section was built in the south of Denmark in 2010/2011. This section now links the harbor and the industrial city of Sønderborg with the central European north-south highway E45 via a highway interchange near the town of Kliplev, enhancing the economic development of the entire region.

The Kliplev Sønderborg Motorway was built by the STRABAG joint venture KMG (Kliplev Motorway Group) and is the country’s first highway to be constructed as a PPP project (Public Private Partnership). The total investment cost for the new motorway section amounted to 148 Milion Euros. The project includes a total of seven interchanges, 18km of by-roads as well as numerous bridges and municipal road underpasses.

KMG used highly innovative construction methods for this project in order to ensure that future maintenance requirements will be minimized. As a result, the 13 new bridges were planned with minimized material in terms of bearings, joints and other construction elements. Thanks to these preventions, KMG estimates to be able to reduce the project’s life cycle cost by more than 40% compared to existing Danish highways.

DSI supplied a total of 180t of St 1860, 150 mm² SUSPA Systems Bonded Strand Post-Tensioning Systems for this important infrastructure project. The well-proven MA 19-0.62" Strand Post-Tensioning System was successfully used for post-tensioning the 13 bridges.

In addition to the manufacture and supply of the post-tensioning systems, DSI’s scope also included installation as well as post-tensioning and grouting on site. Work on this project began in 2006. The opening of the bridge for traffic is scheduled for the early summer of 2012.

Based on the positive experiences during the construction of this new section, Denmark is currently considering using the PPP model for future road construction projects.
