Like all the roads in Scilly, there are very few road signs or markings, and the route number is not marked at all.
The A3111 and A3112 roads join the A3110 at Parting Carn. Both run via different routes to the main settlement of the island, Hugh Town; the A3112 however also runs by St Mary's Airport and through Old Town.
