Conversion and reconstruction works of the Aachen Motorway Junction hub

The Aachen Motorway Junction is one of the most significant road-traffic hubs for goods traffic throughout the European Continent, and has now been converted into one of the most effective nodal points for European East-West road traffic connections.

The traffic frequency of currently up to 140,000 road vehicles daily, will according to traffic experts increase in the coming years to around 200,000 road vehicles per day. The five-way motorway junction hub is a rarity in Germany and causes unusual overlay interference conditions, problematic entanglements and unwanted intersectioning of the traffic flows.
 
In 2009, the initial construction stage was also the commencement of the contract works awarded to the PORR Corporation.

Thereafter, followed contracts for the 7th construction stage, the 3rd construction stage  and the 4th construction stage. Since then, tangent routes have been diverted, exit lanes have been newly constructed in accordance with the specification requirements of the Highways Department of the German Federal State of North-Rhine Westphalia and completely new lanes laid down and added.

The 1st and 3rd construction stages comprised the conversion of the motorway junction hub on the A 44 motorway proceeding from the Belgian region. The 7th construction stage comprised the conversion of the A 4 motorway from the junction hub in the direction of the regions of the Netherlands. During the 4th construction stage, the conversion of the A 4 motorway lanes from the direction of Cologne in the direction of the Netherlands was completed, as well as the construction of the entrance and exit lanes to the superimposed A 44 motorway, in the direction of the Belgian regions as well as in the direction of Dusseldorf, Germany.
