Traffic counts on the A 93: The path to the new Danube bridge begins!

Traffic counts on the A 93: The path to the new Danube bridge begins!

As part of the infrastructure project “A 93, general repair of the Pfaffenstein tunnel and replacement construction of the Pfaffenstein Danube bridge”, comprehensive traffic counts will be carried out at the junctions of the A 93 in calendar week 48, from November 25th to 27th, 2025. The aim of these counts is to calibrate the city of Regensburg's traffic model for the analysis status in 2025 and to create a traffic forecast for the year 2040. This measure is intended to help better plan and understand traffic conditions in the long term, reports Lappersdorf.

The counts are carried out over a period of 72 hours using a total of 10 video cameras. The cameras will be attached to existing masts on November 24, 2025 at a height of approximately 3 meters. An important detail is that the image quality is adjusted so that personal data is not captured; a distinction can only be made between vehicle types. After the counts are completed on November 28, 2025, the cameras will be dismantled.

Nodal points and technology

The traffic counts take place at several junctions:

• Regensburg-West (Clermont-Ferrand-Allee/Einmündungen Zu- und Abfahrtsrampen)
• Regensburg-Pfaffenstein (Frankenstraße/Einmündungen Zu- und Abfahrtsrampen)
• Regensburg-Nord (Einmündungen Zu- und Abfahrtsrampen im Lappersdorfer Kreisel und Kreuzungsbereich Regensburger Straße/R18)
• Regensburg-Regenstauf (R21/Einmündungen Zu- und Abfahrtsrampen)

In the subsequent project planning, various variants are being discussed. An option known as the zero variant only provides for the renewal of the inner shells in both existing tubes and would result in a minimal reduction in the roadway width from 9 to 7.5 meters. However, this variant could not ensure any significant improvements in traffic flow and traffic safety on the A 93 and will therefore not be pursued further autobahnen-regensburg.de explained.

Future prospects

In contrast, a new construction variant would include the construction of a new tunnel tube for the Holledau direction and the construction of another Danube bridge. With this option, final roadway widths of 12.5 meters in both directions are planned. However, both variants also require extensive interventions in existing protected areas and properties with residential buildings. The ability to obtain approval and implementability is particularly important here, so that in both cases there can be extensive and lengthy planning approval procedures.

Overall, the current planning status shows that significant improvements to traffic flow and safety on the A 93, some of which are considered necessary, have not yet been conclusively clarified in the discussion. Further information about the current planning will be available on the website www.a93-pfaffenstein.de published.
