Major Scheme

Part of our programme of improvements (value >10m)

Cost:  TBC


What is happening?

We are proposing to improve the A19 by constructing a flyover to take the A19 over the Testos junction. Entry and exit slip roads will connect the A19 to the new roundabout, requiring a slightly larger roundabout than is currently in place.

Under the Highways Agency’s current preferred option for the improvement the A19 carriageway will move slightly to the west and will be raised above ground on an embankment. This will carry it over the roundabout via two bridges. Traffic to and from the north at Downhill Lane Junction will be linked via new parallel connector roads to the new south facing slip roads at Testos Junction.

Public Consultation

The public consultation documentation is available to view on GOV​.UK including a questionnaire open until 28th November 2014 to capture views.

When and where is this happening?

The Testos junction connects the A19 and the A184, south of Newcastle. It is of both local and regional importance providing links between Tyneside, Wearside, East Durham and Teeside. The A19 is a strategic route that provides an alternative to the A1 between North Yorkshire and North Tyneside.

In the 2013 Autumn Statement, the Minister announced the A19 Testos Junction Improvement as a potential scheme to be developed further.

Why is this happening and what will it cost?

In 2001 traffic signals were installed at the junction, which reduced congestion and improved safety. The traffic signals were subsequently renewed in 2012, with the high friction surfacing being replaced at the same time. The current junction handles around 80,000 vehicles per day and is often congested especially during rush hour periods. Expected growth in traffic means that the roundabout will become a bottleneck, resulting in longer delays and more severe congestion, increasing driver frustration.

How will the scheme be carried out?

This scheme has not been approved to move forward to construction so we do not yet have information about how this scheme would be carried out.

What are the benefits?

The objectives of the scheme are to:

  • Improve road safety at the junction
  • Relieve congestion associated with the roundabout
  • Minimise the environmental impact of the proposals and mitigate them where possible.

How do I find out more information ?

More information will be posted on this project page as it becomes available. You can subscribe to be alerted when updates are made.

Landscape and visual effects

All the options would cause the loss of some trees and hedges. Three overhead powerlines running west across the A19 from a large sub-station in Mount Pleasant Marsh would be diverted to new underground ducts for the preferred option.

The non-preferred options would affect would affect power lines to a lesser extent but at least some pylons would require replacement. The preferred option uses the least land while its new embankment and lighting would be the least visually intrusive.


The preferred option would have a minor effect on the Site of Nature Conservation Interest at Mount Pleasant Marsh. The other options would have a minmal effect on other habitats such as hedgerows, and on a wildlife corridor.

Cultural Heritage

The preferred option has no significant effect whereas the other options considered would affect the historic value of Scots House and damage the wider heritage landscape.

Land Use

The preferred option is the only one that would not split farmland, which could potentially make some land uneconomical to farm.

Water Environment

All options would improve protection for watercourses from pollution compared with the existing situation.
