The RA15 is connected to the A18 to Messina, the A19 to Palermo and to all of the major national roads of Eastern Sicily.

The initial project had on the plans a second service road going through the city called By Pass East (today's A18dir) but due to the highly urbanized situation of Catania the project has never been completed leaving the road to terminate in the northern part of the city.

In the southern part of Catania, in July 2010 was completed another 5,0 km of service road called "Asse attrezzato", part of the initial project of the 1970s.

This service road connects the motorway A19 to Palermo and the RA 15 to the southern part of the city.
