Overview
- Traffic is now one lane in each direction with a 7.5‑ton limit, and travel and scheduled buses are exempt.
- A continuous sensor program on the span flagged damage, then sampling confirmed embrittled prestressing steel at two spots near Ammonstraße and the inner‑city end.
- The monitoring system uses 122 acoustic sensors installed since November 2024 to catch changes inside the concrete before they worsen.
- Engineers are preparing temporary supports and a longer‑term fix that could replace the asphalt layer with ultra‑high‑strength concrete to add waterproofing and load‑bearing strength.
- The city aims to keep the bridge in service for about ten years under close monitoring, and it says routes beneath the structure remain safe.
