Drones used as engineers prepare for A66 trans-Pennine dualling work

A Highways England engineer launches a survey drone.

Highways England is using drones as it prepares to deliver the £1bn A66 trans-Pennine dualling improvements.

In one of the most extensive aerial surveys of its kind, drones are taking to the skies along the A6 to help shape the final designs for dualling the remaining sections of the 50-mile route as well as creating new junctions and other improvements.

Highways England’s Matt Townsend, head of development for the project, said: “Dualling the rest of the A66 will be one of the biggest single construction projects ever delivered in the North.

“The drone surveys, alongside more traditional methods, will help us fully understand the varied construction environment along the 50-mile route and allow us to provide robust designs as we head into the final public consultation and planning application process later this year.”

Specialist ground investigations have been going on since February but topographical surveys – to help engineers establish and understand the lie of the land – are also now taking place and will help provide 3D modelling before the new bypasses and other dual carriageway sections of the route can be built.

The topographical surveys are using a combination of new and old technologies with a traditional measuring stick approach being supplemented with drone measurements from the air and vehicles mapping the land from the road.

There are four elements to this phase of the work:

  • Conventional surveying and traversing using traditional total stations and static GPS
  • Mobile mapping which is a laser technology which is vehicle mounted for large motorway and carriageway surveys to mitigate the requirement for traffic management and the need for survey staff on the carriageway
  • Drone surveys using the latest in surveying drone technology in this case fixed wing with integrated GPS to reference to the National Grid
  • Infill surveys GPS surveying referenced to the Ordnance Survey active GPS network

Mr Townsend said: “A great deal of the design will be with our surveyors’ feet planted firmly on the ground using traditional theodolite-based measuring and mapping.

“However, using mobile mapping from vans and from the drones will allow us to build up a richer, more accurate picture of the landscape for our designs.

“The drones give us a freedom and range which is hard to achieve from the ground and allow us access to land without disturbing anyone.

“The ground investigations and landscape mapping are vitally important as we head towards a final public consultation on the options and submitting our application to the Planning Inspectorate which, subject to the outcome, will allow us to start construction in 2024.”

The project is the biggest ever investment in a single road project in the north with all remaining single carriageway sections – totalling 18 miles – of the A66 between Penrith and Scotch Corner being dualled.

Officials say the project will transform cross-country journeys, supporting Northern Powerhouse aspirations for better, less-congested connections and economic prosperity and sustainability.

They say dualling all the remaining single carriageway sections of the route will tackle congestion – providing quicker, safer and more reliable journeys for all road users and boosting the economy of the North.
