Translated to English by Deepl.com:

The "Via Mogadiscio" marked on OSM is probably a dead end? There seems to be no underpass under the railroad tracks and under the "Strada di Grande Communicazione Firenze-Pisa- Livorno"? It can't be that you can't get to the Grimaldi Lines quay either on foot or by bicycle! The "Strada di Grande Communicazione ..." seems to be a freeway that is neither accessible by foot nor by bicycle?
