This article is about the Class III road numbered C19 maintained by DfI Roads.
For other roads numbered C19, see C19
The C19 is quite long by class III standards, but this is in part due to a long spur along part of its route. The road starts on the A52 (Crumlin Road) in Ligoniel, a suburb of north west Belfast. Moving out of the city, the road quickly climbs into the hills and up onto the open moors and roughly follows the A52 as it does so. The next section of the road is generally very straight as it turns to the west and, rather unusually, it passes through a T junction marking the terminus of the B39. However this is not necessarily set in stone as many maps do not show the B39 continuing beyond the A52 to terminate on the C19. Moving on swiftly, another T junction is reached with the C19 both continuing west and turning off to the south. The road west remains fairly straight as it crosses the B154 at a crossroads and soon terminates on the A52 nearby. Meanwhile the road south passes through a few more kilometres of countryside along Budore Road to also meet the B154, this time south east of Dundrod. However unlike the other route of the C19, this one terminates on the B154.
