Description
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 St. Augustin-West interchange and the Liburer Heide T+R facility. Extensive noise protection facilities have to be erected because of the development close to the motorway on both sides. The measure includes 12 intersections and 3 junctions that must be newly constructed or adapted to the planned cross-section. Furthermore, several infiltration and separation basins will be constructed as part of the restructuring of the surface drainage system.
Construction length: 5.5 km
