Traffic chaos threatens: B14 diversion from October 5th between Nellmersbach and Backnang
From October 5, 2025, there will be traffic restrictions on the B14 between Nellmersbach and Backnang/West. The reason for these measures is urgent work as part of the new construction of the B14, in particular the demolition of the existing structure across Schöntaler Straße. The responsible authority, that Stuttgart Regional Council, will reroute traffic and move it to a temporary location. This measure affects the area between the Murrtal viaduct and the Backnang/West junction.
The diversion will be necessary to ensure the safety of road users during the demolition work. Please note that a complete closure of the B14 is not necessary, but short-term traffic restrictions are to be expected. The traffic reallocation is implemented in both directions to optimize workflow and safety. ZVW reports that Constant information about the progress of the construction site is guaranteed through the VerkehrsInfo BW app.
Redirection details
As part of the diversion, traffic will be moved from the existing carriageway to the immature bypass route. The work will take place in close proximity to the existing road, requiring additional precautions. This is part of a comprehensive project carried out as part of the Federal Transport Infrastructure Plan (BVWP) 2030 was tackled. The creation of the BVWP is based on around 2,000 project proposals for the expansion and construction of transport routes, which were evaluated in order to determine their necessity for future traffic.
The BVWP includes projects not only for roads, but also for railways and waterways. Dossiers have been created for each of these projects, which contain administrative, economic and environmental assessments. This information can be accessed in the PRINS project information system, which increases the transparency and traceability of the planning processes.
The construction work on the B14 is part of a larger strategy that aims to sustainably improve traffic conditions in the region, which should not only improve the efficiency of traffic flow, but also the safety of road users. The Stuttgart Regional Council asks the population to understand the temporary restrictions caused by the necessary work.
