|Route outline (key)|
The A4049 follows the Rhymney Valley in South Wales. It does not get as far north as Rhymney itself, although it used to.
The route starts on the A472 at Bryn, to the west of Pontllanfraith. A short dual section leads to a roundabout, after which the road runs west and then north, soon becoming urban. It meets a spur of the A469 at Pengam then, on the southern edge of Aberbargoed, reaches a roundabout from where an unclassified road heads west to meet the A469.
The road continues north through the town before following a vertiginous route into New Tredegar, whose town centre is bypassed by a modern relief road. It turns left to cross the narrow Rhymney River and then climb steeply to zigzag over the railway line by Tir Phil station. The road ends a short distance further on where it meets the A469; that road TOTSOs here, which is a pointer to the fact that it is a newcomer.
Originally, the A4049 continued north along what is now the A469 and then the B4257 through Rhymney to end on the A465 at Rhymney Bridge. It was cut back to Tir Phil in 1935 when the A469 was extended north.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
