Overview
- The A7 including the Elbtunnel will be fully closed for 55 hours from Friday 22:00 to Monday 05:00 to complete final works on the K20 Hochstraße Elbmarsch and carry out maintenance, with large signed diversion routes in place.
- The Mainbrücke on the A671 near Hochheim will be fully closed for concrete works from Sunday evening until early Monday morning, after which traffic will be reduced to one lane per direction while follow‑up work continues into October.
- Regional authorities have scheduled several multi‑month projects that will keep ramps and sections closed, most notably an A59 pavement renewal from 2 October expected to last about eight months and ramp closures at the A73 Buttenheim interchange through the end of 2026.
- Multiple serious accidents have forced emergency full closures and long clearances, including two separate heavy collisions on the A3 near Erlangen on 24 September and a fatal A99 crash in Munich that required crane‑assisted recovery and police investigations.
- The Autobahn GmbH and police are using concentrated night/weekend shutdowns, prefabricated and compact construction methods to shorten work windows, while warning drivers to follow large detours, form Rettungsgassen for emergency access, and avoid affected cities when possible.
