A 59 - 6-lane expansion of T+R facility Liburer Heide to AS Airport

The section of the A 59 between the Cologne-Porz interchange and the Bonn-Ost interchange has very heavy traffic (DTV2025 = 121,500 vehicles/24h). The currently existing 2 or in some cases 3 lanes per direction and the lack of hard shoulders in some sections represent a considerable performance and traffic safety deficit.
The planning includes the continuous 6-lane expansion of the section between the T+R facility Liburer Heide and the airport junction (connection to Cologne/Bonn Airport). Extensive noise protection facilities have to be built on both sides of the motorway. The measure includes 13 intersections and 3 junctions that must be newly constructed or adapted to the planned cross-section. Furthermore, a new tank and service area will be built, as well as several infiltration and separation basins as part of the restructuring of the surface water drainage system.

Construction length: 7.2 km
