Deep Lane junction improvements begin in June

Some of the funding will improve access in Sherford

Posted on: 25 May 2016

The first phase of an essential two-part project to improve the Deep Lane North Junction in Plympton begins on Monday 13 June 2016.

Phase one includes replacing the existing Ridgeway Roundabout with a signalised junction to increase capacity and improve traffic flow. This is scheduled for completion on 31 March 2017.

Local residents and the general public have the chance to view the Deep Lane Phase 1 plans and traffic management proposals at an exhibition. This is being held on Thursday 9th June at Chaddlewood Farm Community Centre, Plympton, between 3pm and 7pm.

Phase two of the scheme will include a new westbound slip road linking a new Park and Ride at Deep Lane to the main street of the planned new community of Sherford. Subject to securing funding, Phase 2 is likely to be delivered by 2021.

Both phases will deliver vital infrastructure and enable the delivery of the new 5,500 home community and the expansion Langage Energy Park.

Once completed Sherford, which was granted planning permission in November 2013, will include schools and community facilities.

Both phases of the road improvements are being delivered by Devon County Council in partnership with Plymouth City Council, Highways England and South Hams District Council.

The cost of the road scheme is £3.1million, with £2million allocated by the Heart of the South West Local Enterprise Partnership through Growth Deal funding.

This funding has enabled the road infrastructure to be delivered more quickly. The remainder of the funding is being provided by the developers of Sherford and the developers of Langage.

Phase 1 includes;

  • Replacing Ridgeway roundabout with a signalised junction.
  • Increasing the size of the existing signalised junction
  • Widening the existing left turn lane for eastbound on slip traffic
  • Realignment of the carriageway and footpath/cycleway
  • Traffic signals optimised and linked to manage traffic flow better
  • Crossing points added to existing pedestrian routes
  • Highway signing, drainage and ducting and new street lights

The work will take place between 7.30am and 5.30pm, although these times may vary.

Delays may affect traffic flow at junctions to and from Wolverwood Lane, Lyneham Inn, Deep Lane (south of the A38 overbridge), A38 eastbound entry slip road and the A38 eastbound exit slip road.

At varying times Sandy Road, Ridgeway Road, B3416 Deep Lane, Ridgeway roundabout (nearest postcode PL7 1QH) and the A38 eastbound entry and exit slip roads connecting to the B3416 will be closed.

Advanced road closure warning signs will be displayed a week before the start of the works, which will detail specific dates.

If drivers are approaching the junction from the north, a suggested alternative route is via B3416/Glen Road, or via the A38 if approaching from the east or south.

Councillor Andrew Leadbetter, Devon County Council’s Cabinet Member for Cllr Andrew Leadbetter1Economy and Growth, said: “Upgrading the junction is vital for the growth in jobs in the area and for the delivery of new homes. I welcome this project, it is good news for people who live and work in the area.”

Councillor John Hart, local Devon County Councillor for Bickleigh and john hartWembury, said: “To carry out these works safely temporary road and lane closures and diversion routes will be in place as required.  Please be assured every effort will be made to minimise the works duration and closures as much as possible, although some interruption may be unavoidable and for this we apologise in advance.”

Councillor Patrick Nicholson, Deputy Leader of Plymouth City Council, said: “The upgrading of the Deep Lane junction ahead of the main development at Sherfordis vital to minimise traffic disruption.

“Plympton councillors and I will continue to liaise with Devon County Council to ensure these works are delivered as quickly and smoothly as possible. The workforce will be working 10-hour shifts in an effort to achieve this.

“Once complete, these improvements will benefit everyone including those living in Plympton, Plymstock and Sherford.”

Cllr Michael Hicks, South Hams Portfolio Holder for Strategy & Commissioning said: “Sustainability and the infrastructure needs of the new community and surrounding area are at the heart of the new town. It was central for the planners and developers behind Sherford that travel through and around the town would be as sustainable as possible, reducing the dependency on cars, whilst easing congestion and ensuring that high quality, high capacity network links were introduced.

“The improvements to Deep Lane will better connect the area and Sherford with Plymouth and the South Hams.”

Chairman of the Heart of the South West Local Enterprise Partnership, Steve Hindley, said: “Yet another important project in our Growth Deal is taking shape on the ground. It’s part of a funding package of £130m awarded to us by Government to deliver transformational projects that support growth.”

The current programme anticipates construction to start on site on Monday 13 June 2016 and finish on Friday 31 March 2017.

    Reading the comments and replies i note the following.
    A 10 hour weekday working contract seems to be about right. I have driven (take this as sat in que) through deep lane to visit my parents regularly and have only seen people working during the day infrequently. I can only conclude that they only work for 10 hours total a day. Or simply put 5 people for 2 hours. There seems to be little to no visible change from day to day. The congestion this is causing is unacceptable but will probably only be an issue for the council when there is an accident in the que on the A38. Or from a road rage incident from the excessive delays.

    Was this project actually planned, or is the planning on job training and work in progress?
    The sub base has been laid on the north side of Ridgeway / Sandy Road only to have a trench dug out for ducting. A properly planned job, by Competent Planners, would have shown this on the working drawings. If it was Competent Planners, is it just an Incompetent Civils Contractor?
    Scarcity of working operatives but plenty of managers would appear to be the vogue for a project that has a drawn out timeline, I assume therefore no penalty cause.
    The traffic management is poor, reflected in the fact that 5 minutes for each change is too long when there are 5 sequences of changes. This is not a simple 3 way traffic light operation.
    Does anyone from Devon Highways carry out a site work audit?
    Or have you forgotten the role of a good Competent Quantity Surveyor?

    • James, thanks you for your comments.

      I have been assured by the Deep Lane Phase 1 delivery team that the project staff have been resourced as required under the construction contract, taking into account a 10 hour weekday working day.

      Traffic management: The configuration and operation of the temporary traffic lights have been discussed with and agreed by the Highway Authorities. The primary aim is safety for road users, followed by a reasonably balanced approach to manage the traffic queuing potential.

      They are manually operated during working hours, with an aim to minimise the potential for queues on the A38, as far as reasonably possible, in the context of the existing capacity of the network.

      Site audit: works are being monitored on behalf of Devon County Council.

      I hope this helps

    I would like to point out that the work being carried out at the Deep Lane junction is badly managed because the tempory traffic lights are not timed correctly plus there are no advanced warnings on the A38 as you approach this busy junction of East Plymouth. This result is extreme hold ups for drivers. Therefore someone from Devon county Council should visit the work site to supervise the work being carried out. Otherwise allow Plymouth City Council to oversee it because Exeter is 44 miles away.
    A good example is when the Tamar Bridge was having two lanes added in 2001 Cornwall County Counci (Truro) were happy for Plymoth City Council to control the work being carried out.

    So more suffering for Plympton residents when phase 2 starts .
    do we really need a park and ride so near the main route in and out of Plymouth .
