The reconstruction of the aachen interchange

The reconstruction of the aachen interchange is one of the largest projects of its kind in germany. By the end of 2021, the federal autobahn gmbh intends to transform the interchange into an efficient hub for european east-west traffic.

Originally, a shorter construction period was planned for the reconstruction. The project was thwarted by the so-called "uberflieger" bridge, which carries A4 traffic from the Netherlands over the A544. The structure should have lasted another 20 years, but roads are being rebuilt.NRW discovered during investigations that the bridge was more severely damaged than expected. Now this bridge has also been rebuilt. The project, originally costing 75 million euros, now includes 91 million euros for, among other things, six bridge replacements and four new bridge constructions. Construction work on the interchange is expected to be completed by 2021. To improve the performance of the interchange, noise barriers will be installed on adjacent sections of the A4 highway to the Netherlands by 2023 and the A44 toward dusseldorf will be widened to 6 lanes.

Today, 260 vehicles travel daily.000 vehicles through the interchange, in ten years traffic experts expect 345.000 per day. The new interchange will have up to 17 lanes side by side in its final stage. The reconstruction of the intersection will be carried out "under traffic": all "traffic relations" will be maintained can in principle also be used during this time – albeit temporarily on narrower lanes and of course at reduced speeds.
