A List of B roads in Northern Ireland.

Routes are listed proceeding North to South or East to West as appropriate.

Originally ran from the A26 in Glenavy to the A3 in Moira.

Swapped with the A26 after the M1 was built; the southern end (at Moira) is now part of the B105 after it was bypassed.

Originally continued to the A2 in Donaghadee town center, but this became a portion of the A48 in the mid-1920s.
