Current information from road traffic: From September 21, 2026, there will be a comprehensive closure on the A99 motorway around Heimstetten. The traffic authorities have announced this measure to ensure that the street infrastructure remains safe and sustainable

.

The block begins on September 21 at 7:00 a.m. and is scheduled to last until October 2, 2026, 5:00 p.m. The measures are necessary to perform both maintenance work and to minimize the wear on the road surface. Drivers can expect increased traffic volume and possibly traffic jams.

Details for traffic blocking

The specific areas that are affected extend over two important sections of the A99:

  • Heimstetten (ZIP 85551), M1, A99 : between the Weißenfelder Straße and M18, Weißenfeld roundabout. The passage is blocked here and the diversion is signposted (length: 701 m).
  • Feldkirchen (ZIP 85622), M1, M 1 : Between M18, Weißenfeld and the Weißenfelder Straße roundabout, the passage is also closed. Here too, a detour is provided (length: 701 m).

This blocking harbors a serious challenge for regular commuting. Road users should adjust to higher traffic loads and plan their routes accordingly to avoid delays.

The Bavarian Central Office for Transport Management will continuously observe the traffic situation during the closure and, if necessary, provide current information. An early information, for example by pursuing traffic reports on news.de is particularly advisable to always be up to date.
