Wuppertal’s A46: Ongoing Disruptions and a Decade of Roadwork
Motorists traveling near Wuppertal, Germany, are bracing for continued disruptions on the A46 autobahn. A complete weekend closure is scheduled for March 20-23, 2026, adding to a series of ongoing construction projects expected to last well into the 2030s.
Weekend Shutdown: Demolition at Cronenberg Interchange
From 8 PM on Friday, March 20th, to 5 AM on Monday, March 23rd, the A46 will be fully closed in both directions between the Wuppertal-Cronenberg junction and the Sonnborner Kreuz. This closure is necessary for the demolition of an existing overpass, making way for a novel connecting bridge. Traffic will be diverted, with routes marked by a “red dot” signage system. The Autobahn GmbH has advised drivers to plan alternative routes and allow for extra travel time.
Long-Term Reconstruction: 20 Bridges to be Rebuilt
The weekend closure is just one piece of a much larger, long-term project. The Autobahn GmbH plans to rebuild 20 of the 31 bridges along the A46 within the Wuppertal area. Currently, four bridges near Wuppertal-Wichlinghausen are already under construction. Work on a new autobahn bridge over the Briller Straße in Wuppertal-Katernberg is slated to start in April.
Beyond Wuppertal: Regional Autobahn Disruptions
The A46 isn’t the only autobahn in North Rhine-Westphalia experiencing significant disruptions. Several other major routes will face closures in March 2026. The A2 near Dortmund will be closed from March 12th to 16th. The A44 between Unna-Ost and Kreuz Werl will be closed from March 13th to 16th. The A562 will also be fully closed from March 13th to 16th. The A43 near Herne will be closed in both directions starting March 20th.
Project Details: A Comprehensive Overhaul
The A46 project, which began with preparatory work in autumn 2022 and major construction starting in early 2023, encompasses more than just bridge replacements. The work includes resurfacing the roadway, upgrading noise barriers (with the installation of noise-reducing asphalt – OPA), and improving drainage systems. The project is expected to capture approximately five years to complete, with a total length of 2.4 kilometers being addressed.
Noise Reduction and Environmental Considerations
The project incorporates noise reduction measures, including the installation of new or upgraded noise barriers. A rainwater treatment facility was completed in early 2024, demonstrating a commitment to environmental sustainability alongside infrastructure improvements.
