Overview
- A new traffic signal on the B16 at Donauwörther Berg has produced regular long outbound rush‑hour queues that residents say reach about 600 metres and have prompted strong local complaints.
- State road authorities and the city share responsibility for the installation and its roughly €150,000 price tag, and officials say the carriageway is too narrow to add a second turning lane so a roundabout was not chosen.
- Complaints focus on safety‑driven trade‑offs that created a bottleneck, with drivers noting heavy trucks struggle to regain speed after stops and local residents raising air‑pollution concerns from increased idling and restarting.
- Nearby junction upgrades show a similar pattern: the Mindelheim Baywa crossing and Sindelsdorf signals continue to need technical aftercare such as inductive loops and timing changes, with some contractor delays slowing fixes.
- Separate major motorway incidents — a hazardous‑goods tanker on the A1 that required specialist pumping and long closures and a three‑hour A95 shutdown after a motorhome overturned — have compounded regional congestion and underline network vulnerability.
