The Stéphanie tunnel in Brussels will be closed for at least a year, the Brussels Transport agency announced on Friday. This decision is due to the results of a thorough check of the tunnel’s stability by an external surveyor, Egis.
The Brussels Travel agency found cracks in the ceiling during inspections at the beginning of January. The concrete was scoured to avoid blocks falling. This check found that the ceiling’s frame is badly corroded, and the concrete’s coating is cracking.
The detailed report says there is a risk the tunnel could become unstable, and pieces could fall onto the road.
