The C112 is a short urban route in Newcastle's west end. It begins on the A189 Ponteland Road in the middle of Nuns Moor, heading west as Fenham Hall Drive. After a short distance it leaves the moor and enters Fenham, where it passes houses and schools then crosses the B1305 Two Ball Lonnen at traffic lights. From here it continues west as Netherby Drive until it reaches the A191 Silver Lonnen, which it multiplexes with for a short distance before turning off onto Slatyford Lane. This curves almost immediately round to the south, passing a large bus depot and further residential development before meeting the A186 (former A69) West Road in Denton Burn. The C112 ends here - the road straight ahead is unclassified.
