Work on a major Norfolk road has recently passed a significant milestone.
The A11 is one of the region’s most important arterial routes, connecting Norwich to London. South-west of the city, the road intersects with the A47 and other roads at a major roundabout – the Thickthorn Junction.

In late 2021, replacement and reconstruction began on sections of the dual carriageway, between Spooner Row and the Thickthorn Junction in both directions – a distance of 9 miles.

Morgan Sindall appointed us to carry out noise and vibration monitoring, in accordance with strict requirements from Highways England.
We also assessed the noise and vibration from some very specialist machinery. With a commitment to sustainability, vast quantities of surface material have been broken up and recycled into the new road surface.
With more than 50% of the work complete, AJA are continuing to undertake independent noise and vibration monitoring at specific sensitive locations near the carriageway.

Our close association with Morgan Sindall has included multiple visits to the site, often at short notice. As a result, the project continues to progress on schedule and should be completed later in the year.
