ROME — Amid predictions that the death toll may rise in the bridge collapse in Genoa, experts warned on Thursday that other potentially deadly threats lurked in the country’s aging infrastructure, but so little information is available that no one can reliably estimate the scale of the problem.

Italian newspapers have rolled out a series of alarming banner headlines. Il Messaggero, for example, pointed to an “Infrastructure Emergency.”

In reality — and this may be of equal concern — it is unclear whether Tuesday’s failure of the Morandi Bridge signals a national crisis. There is no national organization that tracks the condition of Italy’s infrastructure and makes public its findings.

A jumble of public, private, local, regional and national agencies operate and maintain the country’s highways, bridges, viaducts and tunnels with little oversight — a system so fragmented that it is sometimes unclear who is responsible for a tract of road or a bridge. In the case of a bridge that collapsed in 2016, killing one person, provincial and national authorities continue to blame each other.
