SGN shuts the Burnell Road and High Street junction from 14 September to 18 October, with Erskine Road, Brunswick Road, Vale Road and Bushey Lane closed in turn until 1 November. Street-by-street dates.

The junction of Burnell Road and Sutton High Street will be closed to traffic from Monday 14 September to Sunday 18 October while SGN replaces the gas main beneath it, the first stage of a £30 million programme to renew 15 kilometres of old metal gas pipes across south London. The gas network operator’s own project page sets out a street-by-street timetable running from 20 July to 1 November, with Erskine Road, Orchard Way, Brunswick Road, Vale Road and Bushey Lane each closed in turn and temporary lights on Oakhill Road (SGN: Sutton, Burnell Road).

The permits lodged on London’s roadworks register say why. SGN is decommissioning and replacing “around 1.5k of gas main between Erskine Road and Collingwood Road no longer fit for purpose”, the entries read, “due to the iron main continually leaking and placing nearby properties and businesses at risk” (LondonWorks register, borough of Sutton). The same register logged an emergency gas escape on Collingwood Road on 13 August, being dealt with until 20 August.

Street by street

SGN’s published schedule for the Sutton phase, which it says was “carefully sequenced” after consultation with Sutton Council and TfL (SGN):

  • Collingwood Road, 20 July to 1 November: work in the verge opposite number 113, no impact on traffic. The register’s permit for this excavation says it is the flow-stop point on a 30-inch medium-pressure main and must stay open for the full duration.
  • Erskine Road, 27 July to 30 August: road closed between the Florian Avenue and Paget Avenue junctions.
  • Orchard Way, 27 July to 1 November: road closed between number 48 and the Erskine Road junction; the register lists this as the site compound for plant, welfare and storage.
  • Oakhill Road, 10 August to 20 September: temporary traffic lights moving along the road with the work.
  • Brunswick Road, 10 August to 4 October: road closed between the Burnell Road and Oakhill Road junctions.
  • Burnell Road and High Street, 14 September to 18 October: both roads shut at their junction.
  • Vale Road, 28 September to 1 November: road closed between the High Street and Bushey Lane.
  • Bushey Lane, 12 October to 1 November: road closed between Vale Road and Collingwood Road.

One caution on dates. The permits on the LondonWorks register do not all match SGN’s page: the register currently carries the High Street permit for 6 to 19 September, Brunswick Road and Burnell Road for 23 August to 12 September, and Bushey Lane and Vale Road for 13 September to 10 October. Permits are routinely varied as a job progresses, so treat SGN’s page as the operator’s working plan and the register as the legal record on the day. SES Water has a separate High Street permit for a new bulk water connection from 6 September to 1 October, so the northern end of the town centre will have utility works of one kind or another from early September to the end of October (LondonWorks register).

What SGN says the closures mean

SGN’s page makes a set of specific commitments for the closed streets (SGN):

  • signed diversions for motorists;
  • vehicle access for residents “maintained from one end of the closure”;
  • parking bays suspended at times, with signage installed in advance;
  • all businesses open, with access to commercial premises maintained throughout;
  • refuse collections continuing, arranged with the council;
  • and bus routes “may be impacted”, with residents told to check with the operator for changes to routes, timetables and stop locations.

The company describes the Sutton job as the first project in a five-year, £30 million south London programme, and says that once it is done “we won’t have to undertake emergency repairs at short notice”. Its stated case for the spend is that not replacing the pipes “risks unplanned gas outages, emergency repairs and greater long-term disruption”, and that new plastic mains cut methane leakage and can carry renewable gases such as biomethane.

What it means for you

If you drive through the north of the town centre, the pinch point is the Burnell Road and High Street junction from 14 September. With Brunswick Road already shut and Oakhill Road under lights, the usual rat-runs between the High Street and Collingwood Road will not be available at the same time; allow extra time and follow the signed diversion rather than trying side streets that may themselves be closed. Angel Hill and Rose Hill are the obvious alternatives, and both carry their own works this autumn: TfL replaces traffic signal poles on Angel Hill on 24 August, and the council rebuilds the Rose Hill footway from 7 to 29 September (LondonWorks register). The current picture for the whole borough is on our Sutton roadworks page.

If you live on one of the closed streets, SGN says you keep vehicle access from one end of the closure, and that parking suspensions will be signed in advance. Bin collections should carry on; if a bay outside your home is suspended on collection day, check the Sutton bin collection days page for the schedule and put bins out as normal. If you smell gas at any point during the work, the national emergency number is 0800 111 999; questions about the project go to SGN on 0800 912 1700 (SGN).

If you use the buses along the High Street, SGN’s own advice is to expect possible diversions and stop changes from mid September and to check with TfL before you travel. We will report the diversion details when TfL publishes them.

If you run a business on the affected streets, SGN says access will be maintained throughout and that all businesses will remain open; its project page invites feedback through a voice survey it is trialling.
