|Route outline (key)|
The B19 was a medium-length B-road in north Northern Ireland.
The road started on the A26 in the centre of Ballymena and headed west, soon crossing the River Main. It went through Ahoghill and Portglenone, where it crossed the River Bann, before meeting the A6 to the east of Maghera. The road ended here.
The B19 number did not last long. In the mid-1920s it was renumbered as part of the A42, which it remains.
