Partial Failure Forces Second Blast to Bring Down Talbrücke Ottfingen

The delayed demolition extended A45 closures and prompted traffic disruption plus an official probe into why four supports survived the first detonation.

Overview

  • The Talbrücke Ottfingen, which was detonated on Sunday, July 19, did not fully collapse after the first scheduled 8:00 a.m. blast when four supports remained standing.
  • Specialist teams had prepared the demolition with about 160 kilograms of explosives placed in 530 drilled holes and roughly 900 metres of detonation cord before carrying out a successful follow‑up detonation around midday.
  • Authorities closed the A45 between the Olpe‑Süd and Freudenberg junctions from 06:00 for safety and the unplanned second blast prolonged the closure, causing delays for summer holiday traffic while checks continued.
  • Autobahn GmbH and the demolition chief have opened a review to find why the initial charges left supports intact and engineers are conducting inspections of the neighbouring carriageway before reopening the road.
  • The operation clears space for a planned replacement as part of the multi‑year Sauerlandline program to renew about 60 ageing major bridges that face greater stress from higher traffic and heavier lorries.
