Flooding, landslides, collapsed walls, damaged bridges and felled trees were among the causes, cited by Luxembourg’s bridges and highways agency in a statement issued a week later, on Thursday 22 July.
While most roads have since reopened to traffic, a dozen, including roads and cycle paths, remained closed with diversions in place.
The agency is checking embankments and bridges in the impacted areas, in particular along the rivers Our, Sûre, Pétrusse, Mamer, Ernz (black and white) and other streams.
It wrote: “At this time, it is too early to make a final assessment of all the damage caused by the bad weather. Where possible, repair work has been initiated. For more complicated situations, experts will have to visit the site.”
A number of the agency’s own buildings were also flooded, including a warehouse in Born, and service depots in Rosport. Estimates of the damage are underway.
