Mountain Road, Caerphilly

The B4623 number was assigned to the pre-bypass route of the A469 through Caerphilly. Although it may seem as though the number is a misprint for the B4263, which also reaches the town, the number did appear on maps and official documentation in the 2000s. It appears that the road no longer exists, perhaps for reasons of confusion. The section to the south of the B4600 in Caerphilly town centre is now an extension of the B4263 whilst the section to the north is unclassified.

The road started at the southern end of the bypass on Caerphilly Common and headed north along Mountain Road, descending into town. After running through the outer suburbs it went over the Rhymney Line by Caerphilly station then joined a one-way loop through the town centre. Northbound traffic followed Castle Road north then skirted the castle grounds to rejoin southbound traffic by the war memorial; that followed the parallel White Street then had to TOTSO right into Bartlett Street. The northbound route passed the shops whereas the southbound route was more residential.

A short distance further north, still by the castle grounds, the B4623 met a gyratory, where it crossed the B4600. Northbound traffic continued straight whereas southbound traffic had to divert around the loop. After becoming two-way again at traffic lights at the corner of the castle grounds the B4263 turned off left then we continued north along the residential Pontygwindy Road. This continued through the outer suburbs and passed a retail park before meeting a roundabout at the northern end of the A469 bypass. The A468 was also met here.
