The A4174 is a major ring road in England which runs around the northern and eastern edge of Bristol, mainly in South Gloucestershire, and through the southern suburbs of the city.

The road was conceived in the 1980s by Avon County Council, and the route of the initial section, east of Bristol, was selected by 1986.

A further section of the southern ring, the South Bristol Link Road, was opened in January 2017 and connects Hartcliffe (west of Hengrove Park) with the A370 near Long Ashton.

[8] There have been several proposals to extend the ring road from the junction with the A4 at Hicks Gate, Keynsham, along the southern edge of Bristol as far as the A370 at Long Ashton.

The 2005 Greater Bristol Strategic Transport Study, commissioned by the regional government office, recommended construction of the new southern route to tackle congestion.

[13] A public consultation elicited 84% opposition to the plan, with objections including the long period of traffic disruption and that no bus lanes would be created, and consequently the council postponed its bid for government money for further consideration.
