A19 road closure from Chapel Haddlesey Bridge to the junction with Wand Lane.

A19 open

The A19 at Chapel Haddlesey reopened on Monday 21 June.


This section of the A19 is built on a causeway, a road on top of a man made embankment through which run small bridges or culverts to allow water to pass back and forth. 

The A19 has regular condition and safety inspections, which found the road to be structurally sound and in good condition prior to collapse. However, following significant rainfall resulting in high water levels over a long period, accompanied by high winds that led to almost tidal type erosion, the road suffered catastrophic damage and it was necessary to close it for safety.

Diversion route

The A19 is a principal road and as with any road closure the signed diversion must follow a road of the same category or higher on the highway network hierarchy. The A19 is classed as Cat 3, as are the two signed diversion routes, whilst the third diversion for HGV’s also uses the M62 a trunk road which is a higher category.

There are other local routes available; but these are not advertised or signed because they have not been constructed to carry the same weight or volume of traffic.

Additional signage to deter motorists from using roads through the villages has been put. It is usually those with local knowledge that choose to use these roads as a short cut to avoid the signed diversion.

North Yorkshire Police are monitoring certain locations for speeding vehicles and there has been an increase in their presence on the roads between West Haddlesey and Birkin following concerns received by residents. If you have concerns about speeding on the diversion route report this to North Yorkshire Police.

Planning and design 

We understand this road closure is inconvenient to the many communities who are adversely affected and that the delay in reconstruction starting is frustrating. Normally the planning, design, procurement and mobilisation for a project of this size is carried out over a year prior to commencement whilst the road is still open to traffic. Unfortunately, in this case the road had to be closed as it was dangerous but the same work needed to be carried out. We have been doing our utmost to get this road repaired so it can be opened to the public as soon as possible.

The most significant issue was that the scale of the damage was unknown. The damage on the surface was visible and quantifiable, however it was clear that there was substantial damage at a significant depth below the surface of the road so we could not be certain of the entire area of that damage. 

Covid-19 delayed the progress further, with national lockdown meaning companies were unable to provide crucial services.

Key dates

The timescale of the work carried out is below:

  • 18 February 2020 the A19 was closed between Chapel Haddlesey and Eggborough, due to collapse following erosion resulting from Storm Dennis.
  • 10th March 2020 water levels dropped enough to allow a full visual inspection, this established significant erosion of the embankment and triggered various excavations in the road to try to establish internal damage. This concluded the scale and nature was both large and complex. Ground Penetrating Radar (GPR) surveyors were instructed but Covid-19 brought progress to a halt.
  • Mid May 2020 designers were considering solutions, ruling out options up to this point and we were negotiating with contractors, looking at procurement options to speed up getting a contractor on site, but the design team did not received results of the Ground Penetrating Radar (GPR) until the 13 May. The results confirmed there were significant voids particularly around the five bridges and culverts. The Ground Penetrating Radar (GPR), like X-rays, cannot tell everything and does not guarantee that all voids are found and that continues to be a risk.
  • End of May 2020 we short cut the contractor procurement process using a national framework and Balfour Beatty were appointed. Balfour Beatty worked closely with the designers using the Ground Penetrating Radar (GPR) information, excavation information and the visual inspections of the embankment to conclude what the most logical and deliverable solutions were.
  • June 2020 survey and design work identified major BT and Gas services near the road and embankment. Discussions with those companies concluded major diversions were required to allow the works to progress. Gas leaks were found that were repaired in June.
  • July 2020 Northern Gas Networks commenced diversion work of the major gas service.
  • August 2020 design work for the 5 bridge repairs was completed and approved, permits were approved for the proposed repairs with the Internal Drainage Board and the Environment Agency. BT carried out their service work.
  • September 2020 Gas diversion work was completed at the end of September ready for Balfour Beatty to commence the main repair work.
  • October 2020 Week commencing 5 October planning of the road surface commenced.

Timescales

In May 2020 our consultants initial assessment was that the construction period, given what was known at that time, was between 6 to 8 months. When appointed at the end of May the contractor Balfour Beatty programmed a start date of the 3rd August and a completion date of 21 May 2021, this would be 9 months construction taking in the Christmas period.

Because the gas service diversion was necessary the start date has been delayed by two months which would have logically put the contractors programme back to the 21 July. The contractor has reviewed the programme and although an initial completion date of the 8 July was tabled, the contractor by further reviewing the programme confirmed a completion date of 25 June 2021. The programme and end date try to take into account the risk of a number of unknowns, hence we remain optimistic that the actual completion date and the date that the road will open to traffic will be earlier.

The reconstruction design addresses the risk of future flood damage to the road as the new embankment will be protected by a ‘rock wall’ against flood erosion. In the unfortunate situation, we experience a further flood event during the construction period; the working method the contractor has adopted will mean the newly constructed sections will be self-protecting. This will ensure we will have minimal abortive work. It is of course inevitable that if we have a major flood during the work the period of construction is likely to be delayed.

We are sorry for the inconvenience and disruption the closure of the A19 is causing but both ourselves and our contractors are fully committed to getting the road reopened as soon as possible.

  • 6C starter layer for the final stretch of road ongoing with the Type 3 granular fill to follow. Next surfacing visit to start 17th May.
  • Stone central have made a good start with the structures, stripping 3 existing sets of parapet wall by Wednesday to ensure we capitalise on the good weather by starting the rebuilding ahead of programme.
  • Scaffolds completed this week for continuity of stonework strip out/rebuild.
  • MSF are back on site continuing with the installation of the BT ducting and chambers to the East verge, completing this next central section to ch. 620.
  • As the BT duct is placed, Jakto are following up reinstating the verge and completing the Macmat reinforcing layer heading south throughout the works.
  • A very productive weekend of Road Planing enabled the base course to be laid this week – 1750 tonne of existing bound carriageway materisl removed from site; 1400 tonne of Base course laid in the following days.
  • Excavation of the southern section of road box started - advanced testing of formation allowing us to minimise excavation depth to increase outputs but unfortunately, after a good spell of firm ground, the soft silty clay layer reappeared. Reactive planning increased haulage almost immediately ensuring no real time loss of production.
  • Drainage works commenced in the southern section on the West side however due to the interface with the now increased depth of excavation to the adjacent road-box, it was agreed to divert labour and plant to verge works on the North section to minimise people/plant interface whilst ensuring resources were being used effectively.
  • Verge works continue with design of two types of geotextile with a subsoil fill.
  • An early finish to the surfacing visit has enabled us to start Type 3 granular fill to the verges ahead of the next visit from MSF to install the BT duct in the East side.
  • Drainage works commenced in the southern section on the West side however due to the interface with the now increased depth of excavation to the adjacent road-box, it was agreed to divert labour and plant to verge
  • After completing the excavation of the Road Box, efforts turned to importing large quantities of 6C starter layer and Type 3 reduced fines sub-base to ensure readiness for the subsequent paving operation.
  • 6B1 rock armour works to the East of the site completed allowing us to commence construction of the Field Access.
  • Verge works are ongoing working from the Northern end southwards using the existing structures as targets.
