|Route outline (key)|
The B109 was a short road acting as an unofficial southern bypass of Bangor. The road was originally unclassified, gaining its number in the mid-1920s. However, it was short-lived and had been declassified again by the late 1940s.
The road started on the A2 on what is now the edge of town and headed east along Rathgael Road. It wasn't long before the A21 was reached; there was a short multiplex to the right and the B109 regained its number by turning left along Green Road. The A21 has been rerouted here onto the Conlig bypass and so the western end of Green Road has been severed.
After leaving Conlig the B109 continued east along a straight road across the fields to end on the A48 at Six Road Ends. This junction was rebuilt in the late 2000s so only four roads meet at a point, with Green Road ending on the direct road from Bangor.
