Overview
- The B16 signal at Donauwörther Berg, put into operation in March 2026, now causes outbound evening queues reaching about 600 metres and has drawn heavy criticism from residents and local officials.
- Planners installed signals instead of roundabouts for cost and space reasons and left no room for two turn lanes, a constraint that funnels traffic into a single-lane bottleneck.
- Multiple recent intersection projects in the region show similar technical shortfalls: some lights run on fixed-time control because induction loops and remote sensors were not yet installed or are limited to a single loop.
- Local authorities say the matter will be discussed in traffic working groups and propose fixes such as reprogramming signals, resizing islands or adding loops, but no definitive modifications have been implemented.
- Separately, a series of large incidents — including a tanker spill on the A1 that required five hours to pump out industrial alcohol, a fatal A6 crash and a major Baumarkt fire in Wedel that deployed about 150 firefighters — produced multi-hour closures and highlighted how single events can amplify regional congestion and strain interagency response capacity.
