Overview

• A 250-kilogram American World War II bomb was uncovered during groundwork for the new Gremberg bridge in Cologne-Gremberg.
• The Düsseldorf district’s bomb clearance service established a 300-metre safety perimeter and ordered full closures of the A4 and A559 at around 14:00, including ramps at Köln-Poll and Gremberghoven.
• At 14:10, authorities confirmed clearance to proceed with defusal, although the exact timing of the operation has not been announced.
• No evacuations have been required and long-distance and regional rail traffic through Cologne continues without disruption.
• This incident follows a July remote detonation of another WWII bomb in Köln-Lindenthal that affected 1,800 residents and underscores the city’s frequent encounters with leftover ordnance.
