Full closure of the A59 from October 15: Large construction site by 2026!
The A59 motorway between the Düsseldorf-Süd motorway triangle and the Monheim junction is largely affected by urgently needed renovation. From October 15, 2025, 9 p.m., a complete closure will be set up in the direction of Leverkusen. The reason for this is the poor condition of the road, especially the unevenness of the concrete slabs, which cause vibrations and damage. “We have a significant renovation project ahead of us here,” explains a spokesman for Autobahn GmbH ksta.de reported.
From October 20, 2025, the section from the Richrath junction to the Monheim junction will also be blocked. The first construction phase is expected to be eight months, in which the A59 remains completely blocked in this direction. After the full closure, remaining work is planned under a single -lifting traffic management before the route is again accessible in two strips.
Scope of the renovation work
The renovation of the A59 not only includes the renewal of the road, but also a comprehensive repair of bridges and a modernization of the drainage facilities. These measures are urgently necessary due to the aging infrastructure and are supported by the recently approved funds of the federal government. Loud bundesfinanzministerium.de A total of 1.1 billion euros are available for the renovation of the motorway infrastructure to strengthen important traffic axes such as the A3 and the A59 and to secure jobs in the construction industry.
The traffic routing is optimized by setting up needs. These are intended to help to better steer the diversion transactions due to the construction sites. The Langenfeld motorway triangle remains a bottleneck regardless of the measures, since the construction site will not be finished in time.
Drivers will have to prepare for an intensive phase of traffic work in the coming months. The renovation will not only affect the roadway, but also the connection to the A3. Important diversion routes flow through this section, which could change traffic in the region.
Outlook on the future
After completing the renovation work in the direction of Leverkusen, the construction site is moved to the opposite lane, where a complete blocking is also due for about eight months. It is important that road users remain informed about ongoing developments inside, since the work is important not only for the users of the A59, but also for national traffic. Autobahn GmbH and the responsible authorities will provide further information on the diversions and changes in the flow of traffic in the next few weeks.
These comprehensive renovation measures are part of a larger plan to improve the transport infrastructure, in which a total of 166 billion euros are to be invested by 2029. The departments are optimistic that these investments will lead to an improvement in road and traffic safety in the long term.
