Traffic chaos in Gemmrigheim: construction site will remain in place until March 2026!
Traffic restrictions in Gemmrigheim have affected the K1625 since September 20, 2025 and will last until March 31, 2026. The reason for the measures is the urgently needed road reconstruction, which serves both to maintain the infrastructure and to adapt to increasing traffic. According to [news.de]. Length of a total of 31 meters and allows a passage width of 3.25 meters. The construction will be carried out in several phases, with the construction of a new roundabout intended to relieve traffic congestion.
The construction project is currently in the third construction phase, which involves opening up traffic via a temporary roundabout. This is intended to improve the connection between the K1624/K1625 near Gemmrigheim and the B27/K1625 near Kirchheim/Neckar.
Complete closure during the summer holidays
A significant part of the construction work took place during the summer holidays, when the junction was fully closed between July 31 and September 14, 2025. This was planned in order to keep the burden on residents and road users as low as possible. During this time, access and exit to the concrete plant and the sewage treatment plant took place via the residential area and the vineyards. After the summer holidays, traffic is expected to be single lane and controlled by traffic lights until the end of the year, which represents a temporary but necessary solution to avoid the construction site, as gemmrigheim.de reported.
Diversions and disruptions
Extensive diversions are signposted for the duration of the construction work. This particularly affects the connections from Neckarwestheim, Ottmarsheim and the motorway access road via the L1115 to Besigheim. Access to Gemmrigheim via the forest road is also guaranteed. Bus routes 573 and 574 are also affected by the construction work; Passengers are expressly requested to find out about diversions and possible stop relocations.
The construction costs for the entire project amount to around 1.5 million euros, with the state of Baden-Württemberg providing funding of around 800,000 euros. With the new roundabout planning, the temporary traffic lights are no longer needed, which should significantly improve the performance of the junction. In particular, taking heavy goods traffic into account is an important aspect of the design.
The district office appeals to citizens to show understanding for the restrictions and traffic disruptions that will occur during the construction period. The construction was progressive and carried out in accordance with the wishes of the population in order to create a sustainable transport hub.
