Partial closure of B14: Kappelberg tunnel affected due to maintenance from today!
Today, October 8, 2025, a partial closure on federal highway 14 (B14) between Fellbach and Stuttgart is causing traffic disruptions. The measure is due to necessary construction work to maintain the Kappelberg tunnel. This reports news.de.
The partial closure particularly affects the section from the Fellbach-Süd junction to the Untertürkheim junction. The number of lanes will be reduced to a width of 3.25 meters over 3.4 kilometers. The restrictions are in effect from October 8th, 6:00 p.m. until October 9th, 3:00 a.m. In addition, the route from Untertürkheim to Fellbach-Süd is also affected, so road users have to expect longer journey times.
Renovation work on the Kappelberg tunnel
The Kappelberg Tunnel, an important traffic artery, is currently being extensively renovated. Around 80,000 vehicles use this tunnel every day, which is why the construction work has a high priority. These are necessary because the technology in the tunnel is now 20 years old and outdated. According to information from SWR The work was completed faster than planned due to a previous full closure.
In addition to the maintenance work and renovation, comprehensive exercises for emergency services also take place in the tunnel. On Sunday, August 17th, a large fire drill will be carried out in the tunnel, which will involve heavy smoke. The fire brigade, rescue services and police test their procedures for emergencies, which is of central importance for the safety of road users.
Diversions will be in place, as with previous closures. A noticeable reduction in diversion traffic is expected, especially in view of the major events taking place in the region, such as the Supercup game between VfB Stuttgart and FC Bayern Munich.
Football fans and travelers on the B14 are therefore urged to allow enough time for their journeys and to use public transport where possible to minimize the impact of the closure.
