Highway drainage improvement works

What are we doing and why?

We have been successful in securing a further £3.2 million in government funding, under the Department for Transport’s (DfT) Local Highway Maintenance Challenge Fund, which will enable us to carry out major maintenance work at eight sites across South Gloucestershire.

A further £0.5 million is being provided in match funding.

At seven of these sites the work will focus on flood resilience, including the replacement and upgrading of ineffective drainage systems. These improvements will bring benefits to the local communities and the traveling public who use these roads. The work will mean that the sites will be able to cope with extreme weather causing less disruption.

The work will also reduce the need for reactive maintenance works and ultimately result in a cost saving for the council.

At New Avon Bridge we are investigating whether the bridge is likely to be at risk of damage due to scour and impact from water borne debris.

All of the sites have previously been identified as being particularly challenging.

The sites include:

  • Gipsy Patch Lane, Stoke Gifford
  • Perrinpit Road/Old Gloucester Road, Frampton Cotterell/Gaunt’s Earthcott
  • Coldharbour Lane, Filton
  • Bristol Road, Frenchay
  • B4509 The Downs, Wickwar
  • B4058/B4059 Yate Road, Iron Acton
  • Stover Road at Frome bridge, Yate
  • New Avon Bridge, Keynsham Road, Willsbridge

 

Background

South Gloucestershire Council has secured funding previously through the Challenge Fund.

This has included:

  • £14 million for maintenance along the full length of the A4174 Ring Road, this included major works at the Bromley Heath Viaduct
  • £12.6 million for major maintenance work along the A403, from Avonmouth Port to the M48 at Aust
  • £3.4 million to improve the flood resilience of ten roads in South Gloucestershire

Traffic management

Traffic management will be required while the improvement work is carried out at the different sites. Information about the traffic management will be shared nearer the work taking place.

Latest Project News

B4509 Yate Road, Iron Acton

Phase 1

Monday 7 June 2021 for approximately 4 weeks

The works needed include lining pipes, jetting water through them to clear debris, cutting roots and CCTV camera survey work. Based on what we know now, it is estimated this phase will take around 4 weeks to complete. However, until the full extent of the collapsed drainage systems can be determined, the work could take longer.

Traffic management

Temporary traffic signals will be in operation between 9:30am and 8:30pm. We will try to remove the traffic signals earlier in the evening where possible.

Phase 2

July 2021 (start date is dependant on duration of Phase 1) for approximately 8 weeks.

Pipe replacement – We will be dig through the road to replace the old, faulty, and collapsed drainage pipes identified during Phase 1. Based on what we know now, it is estimated the work will take around 8 weeks to complete.

Traffic management

Most of the work will be carried out under temporary traffic signals which will be kept in place 24 hours a day, seven days a week at times. When possible, we will remove them at the end of the day. We may need to close the road to all traffic for some of the work with a signed diversion route and we will provide details closer to the time.

These dates and timeframes may be subject to change and we will keep the local community up to date.

 

B4509 The Downs, Wickwar

We will be working on the B4509 The Downs. This will be split into two phases.

Phase 1

Will start on Tuesday 6 April and take approximately 9 weeks. This will involve digging out and replacing defective drainage pipes.

Traffic management

From Tuesday 6 April, the B4509 The Downs will be closed to traffic, between its junction with High Street and Station Road and its junction with Westend Road, Wickwar. This will be for approximately 2 weeks.

From Monday 19 April, the B4509 The Downs will be closed to traffic, between its junction with Westend Road, Wickwar, and the entrance to the quarry. This will be for approximately 3 weeks.

From Monday 10 May, temporary traffic lights will be in operation along the B4509 The Downs, between its junction with the B4058 and the entrance to the quarry. This will be for approximately 4 weeks.

These lights will be working 24 hours a day and it may also be necessary to close the road at certain times.

Phase 2

From Monday 2 August and take approximately 14 weeks. This will involve using an excavator to desilt existing ditches.

Traffic management

The B4509 The Downs will be closed to traffic from this date, between its junction with the B4058 and its junction with Westend Road. This will be for approximately 14 weeks.

When the road is closed there will be a signed diversion route in operation via the B4060 Wickwar Road, Peg Hill, the B4059 and the B4058. We will keep access to properties and businesses as much as possible.

Bus passengers

During the road closure bus services that travel along the road will need to be diverted.

Further information will be available nearer the time on the Travelwest website.

 

Most of the work will be carried from Monday to Friday during the day. There will be times we will need to work overnight or at weekends.

We apologise in advance for any inconvenience this will cause.

We may change these dates and timeframes but we will keep the local community up to date.

 

Frenchay site

We will be repairing and replacing drainage pipes along a section of the B4058 Bristol Road/Frenchay Park Road in Frenchay.

This will be from the mini roundabout at the junction with Begbrook Park to beyond the junction with Old Gloucester Road.

The work being carried out along the B4058 Bristol Road/Frenchay Park Road will be split into two phases.

 

Traffic management

Traffic management will be necessary to help us carry out these works.

Phase 1

Will start week beginning Monday 22 March and will take approximately 2 weeks.

During this phase of work there will be temporary traffic lights in place on B4058 Bristol Road/Frenchay Park Road.

The lights will only be used during the day. There may be times when the lights must remain in place around the clock, but we will try to keep this to a minimum.

Phase 2

Will start on Tuesday 6 April. This involves replacing drainage pipes and will take approximately 4 weeks.

During this second phase of work we will need to use a combination of temporary traffic lights and a complete road closure. The temporary traffic lights will need to be used around the clock for safety reasons.

We will update the local community with any changes to these dates and times.

 

Road closure

The B4058 Bristol Road/Frenchay Park Road will be closed from the mini roundabout at the junction with Begbrook Park to beyond the junction with Old Gloucester Road when we need to close it.

During the road closure there will be a signed diversion route and we will try to keep access open for residents and businesses. Gatemen will be employed at each end of the closure to let residents into the closed road.
