Back then most of the trucks were made by IVECO, hence FIAT. This is the same reason highways are quite developed across Italy, while Milan is the only place with proper infrastructure in place for commuters. It's the same reason Turin had to wait until early 2000s (before the Olympics) to get an underground rail. The biggest issue with Sicily infrastructure is that most of the rail lines are single tracks, plus southern of Salerno you don't have high speed trains. Therefore the bridge itself cannot make much of an impact without fixing the infrastructure at both sides of the (hypothetical) bridge.
