Route
The B501 is a short B-road to the north of Belfast city centre.
The road starts at traffic lights on the A2 York Road and heads northwestwards along the largely residential Limestone Road, crossing the B126 at another set of traffic lights one block afterwards. The A6 is then crossed, again at traffic lights, on the corner of the Waterworks park and the road then follows Cavehill Road, skirting the edge of the park, which lasts almost all the way to another set of traffic lights. The B501 continues north to end at traffic lights on the A55 North Circular Road.
History
On classification in 1923 the B501 only ran between the A2 and the A6. However, the road is not marked on the 1926 OSNI Road Map; it is not known whether the original B501 was soon declassified, or this is just a mapping error.
Later maps still claim Limestone Road to be unclassified but give Cavehill Road Class II status (but no number), with its northern end on an unclassified road on the edge of the city. It is not until more recently that the B501 was shown with its current route on maps.
