South Gloucestershire motorists are being warned of a month-long overnight closure on a busy stretch of the A4174 ring road as essential reconstruction and resurfacing works begin on Monday 27 July.
What is happening and when
The southbound carriageway of the A4174 between the Dramway and Carson's Road roundabouts will be closed overnight while crews carry out surface reconstruction. Work will take place weeknights from 8pm to 6am, Monday to Friday, and the road will be reopened during daylight hours. The programme runs until 21 August.
How drivers will be diverted
South Gloucestershire Council's Street Care team has arranged a signed diversion routing traffic around the closed section via the parts of the A4174 that remain open and sections of the B4465, A46 and A420. The diversion is designed to return drivers to the A4174 beyond the closures.
"We are sorry for any inconvenience caused while these essential works are taking place."
Additional daytime restrictions
Separately, the council's annual A4174 ring road clean-up will begin at Hicks Gate and proceed in stages towards Filton. These works will involve partial lane closures off-peak between 9.30am and 3.30pm and are scheduled to continue until 26 August. The council says the measures are necessary to protect the safety of the clean-up and cutting teams.
- Overnight reconstruction: A4174 southbound, Dramway to Carson's Road roundabouts — 8pm–6am, Mon–Fri, 27 July–21 August.
- Daytime clean-up: staged partial closures off-peak (9.30am–3.30pm), Hicks Gate to Filton — until 26 August.
- Signed diversion: via unaffected sections of A4174 and the B4465, A46, A420.
Local impact
The A4174 forms part of the ring road network around north and east Bristol and is a key route for commuters, local businesses and bus services. While the overnight timing is intended to limit daytime disruption, drivers who travel late in the evening or early morning — including shift workers and freight operators — should plan alternative routes and allow extra time. Daytime lane closures for the clean-up may also slow journeys along the route during school hours and the afternoon peak.
| Work | Location | Times | Dates |
|---|---|---|---|
| Reconstruction & resurfacing | A4174 southbound (Dramway–Carson's Road) | 8pm–6am, Mon–Fri | 27 July–21 August |
| Ring road clean-up | Hicks Gate to Filton (staged) | 9.30am–3.30pm (off-peak) | Until 26 August |
Road users are advised to follow the signed diversions and allow extra journey time while the works are in progress. The council has apologised for the disruption and highlighted that the timings and staged approach aim to reduce the effect on daytime traffic where possible.
Further updates and any changes to the schedule will be published by South Gloucestershire Council Street Care in due course.
