On Monday, dual federal highways will guide the way towards the open countryside.
The southern bypass of Pirna, Saxony's most expensive road construction project, is nearing completion, with construction of three of the five vaults for the Gottleuba bridge already underway. However, the project has been met with controversy, particularly regarding the installation of a traffic light on the new bypass.
The traffic light, situated at the intersection with the B172, has been a contentious issue due to its potential to slow down traffic on the bypass. Opposition to the traffic light stems from concerns that it could counteract the primary goal of the bypass, which is to enable smooth, fast traffic flow around the city.
In major bypass constructions, traffic lights can potentially cause intermittent stops, delays, and congestion, which could be more pronounced in the southern bypass of Pirna due to the project's aim to improve regional connectivity and traffic capacity. A ramp without traffic lights would have required more space, time, and a change to the entire planning process, according to the Saxon Ministry of Economics.
The new detour, in effect from Monday, 12:00, will not have traffic lights but will have a speed limit. Interior construction with tunnel technology and lighting will soon begin in the Kohlberg tunnel, according to Deges. Traffic will be diverted from the road for 660 meters to allow for construction freedom.
The project, initially planned for 97 million euros, is now estimated to cost over 236 million euros. Work is currently underway to connect the bypass to the B172 above the Pirna sunstone. The Kohlberg tunnel's shell construction is scheduled to be completed this year, with the completion of the entire southern bypass project expected in autumn 2026.
Further increases in construction costs are not ruled out, but the benefits of the bypass are anticipated to outweigh the costs. The new bypass is expected to significantly improve traffic flow and reduce congestion in the Pirna area. The Gottleuba bridge, already noticeable from a distance, will be a key feature of the bypass, providing a scenic route for drivers and pedestrians alike.
In conclusion, while the traffic light on the southern bypass of Pirna has been a source of controversy, the project is progressing and is expected to provide significant benefits for the region when completed in autumn 2026. The new detour, in effect from Monday, will allow for the interior construction of the bypass to continue smoothly, with the hope that the benefits of the bypass will outweigh the costs and provide a much-needed improvement in traffic flow for the Pirna area.

The construction of the new detour for the southern bypass of Pirna, without a traffic light, was designed to minimize potential interruptions in the automotive industry and improve transportation efficiency. The project aims to bolster the regional industry by facilitating smooth and fast traffic flow, reducing congestion costs in finance associated with slow transportation in the Pirna area.
