The A6023 road runs for 5.5 miles (8.9 km) from Conisbrough to Wath-upon-Dearne via Mexborough and Denaby Main. In the east, it starts at, and passes Conisbrough Castle. A short section of the road over the railway line between Doncaster and Sheffield was bypassed in 2002. The bypass was projected to cost £5 million, and had been planned for some time. The diversion meant building a bridge to the west of the level crossing over the railway and adjacent River Don. The western end of the road which runs through Manvers Way Business Park, is built on the old formation of the railway lines serving the Midland Railway's station at Wath, and the Manvers coal and coke complex.
