The B20 is a short B-road in north County Down.
The road starts at traffic lights on the A2 at Crawfordsburn, as that road turns slightly inland and the B20 now forms the road closest to the coast. Our road heads east through Crawfordsburn itself and along a short relief road past the western half of the village centre. After a short rural section the road reaches Bangor and enters town along Crawfordsburn Road.
After going over the Belfast to Bangor railway line by Bangor West station the road splits at a roundabout. The right fork, Brunswick Road, recrosses the railway line to end at traffic lights at the old A2/A21 junction. The A2 has now been rerouted onto a bypass so it appears that only the latter remains.
The original route of the B20 continues ahead from the roundabout onto Bryansburn Road. It used to continue along Central Avenue to end on the A2 Main Street but it has now been diverted onto the wider Gray's Hill to come within sight of the sea before ending on the B21 (former A2) at traffic lights.
