It starts at a roundabout near the old TA site at Repton Park just south of M20junction 9, where the A20 and A28 meet, then runs into the town centre, bypassing it to the north. It then passes some industrial estates and up to Willesborough, where it meets the rather overcrowded junction 10.
The short section between the northbound entry slip and the main roundabout at that junction is a trunk road and managed by Highways England. Otherwise, the road is maintained by Kent Council.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
The A292 once formed the whole of the Ashfordring road, which was a one way free-for-all two miles long and varying between three and four lanes wide, right around the town centre. It was infamous for boy racers, driving instructors allegedly advised their pupils to exceed the 30 mph limit and Jasper Carrott even cracked jokes about it on a visit to the town. Due to the poor safety record, the ring road was turned back into two way traffic on 1 July, 2007. The south and western sections are no longer a through route, but part of a "shared space" scheme with a 20 mph limit. The A292 only covers the north flank of the former ring road, with the eastern section, Station Road, being part of the A2042.
