|State roads in Croatia|
D120 is the main state road on island of Mljet in Croatia connecting Mljet National Park and resorts on the island to Sobra and the ferry port in the town, from where Jadrolinija ferries sail to the mainland, docking in Prapratno and the D416 state road. The road is 42.9 km (26.7 mi) long.
Traffic is regularly counted and reported by Hrvatske ceste (HC), operator of the road. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road connects a number of island resorts to the mainland.
