Düsseldorf experienced significant disruptions and closures due to heavy rainfall that began Monday night and continued well into Tuesday. The German Weather service had issued warnings for flooding as the rain intensified.
The A46 tunnel, in the direction of Wersten, was wholly blocked due to substantial water accumulation on the roadway. Traffic was rerouted in Bilk, and motorists were strongly advised to seek option routes and avoid the area.

Another heavily impacted area was the underpass of Münchener Straße in Benrath, at the transition to Cäcilienstraße and Forststraße. This underpass was also impassable.Officials noted that the drainage systems were overwhelmed by the sheer volume of rainwater, a common occurrence during intense downpours.
Authorities are monitoring rising water levels, but the situation is considered uncritical, with expectations of relief as the rain tapers off.
One driver, who “underestimated the water depth,” found their BMW stranded in the flooded underpass. The vehicle was later towed.
As of 9:25 p.m., the speed restriction in the A46 tunnel was lifted, though traffic jams persisted. The Düsseldorf district government confirmed rising water levels but stated the situation remained uncritical, anticipating a general easing of conditions throughout the day. Rain was expected to cease entirely by the afternoon.
Residents are strongly urged to remain informed about regional flood developments via the NRW flood portal and the flood center.
