Overview

• The tunnel was reopened at 21:50 on Saturday after IT control system renewal works concluded earlier than expected
• The weekend shutdown began Friday evening to modernize critical IT systems installed since the tunnel’s 2017 opening
• Saturday’s closure led to significant congestion on the A7 and overloaded nearby detour routes
• Autobahn GmbH has scheduled one more overnight shutdown from August 16 to 17 to complete remaining upgrade tasks
• This project is part of a broader initiative to enhance safety features and expand capacity across multiple Hamburg A7 tunnels
