A11 concrete road reconstruction at Wymondham
We’re reconstructing sections of the A11 carriageway between Spooner Row and the Tuttles Interchange at Wymondham in both directions. Work started on 29 May 2022, and is due to be completed in late summer 2023.
We're reconstructing the A11 between Spooner Row and Tuttles Interchange at Wymondham. Work started in May 2022.
Reconstruction involves completely removing the concrete road surface and some of the foundations, before rebuilding the road and resurfacing it with asphalt.
The East region has the highest concentration of concrete roads on our road network, including the A11, A14, A12, A120, and M11.
Around half of the old-style concrete roads will either have repairs or will be replaced during the next five years.
We’re using innovative ways of working and new technology to provide a modern road that will last for decades to come. This will also make it easier and quicker for us to carry out repairs in the future.
This video explains the process we go through to rebuild concrete roads:
Why we need the scheme
The surface of concrete roads that were designed between the 1950s and 1970s have an average life span of 50 years. Their surfaces are now reaching the stage where they will need to be repaired or replaced for safety reasons, and to help them be less noisy and better to drive on.
In 2021, we made repairs to 4 miles of the A11 road surface between Tuttles Interchange in Wymondham and Thickthorn, in both directions.
Now, we're rebuilding and resurfacing the A11 road carriageway between Spooner Row and Tuttles Interchange.
About this scheme
We started our work to reconstruct this section of the A11 road in May 2022, and expect to finish by September 2023, subject to weather conditions.
By the end of 2022, we’d reconstructed 5.3 miles of the A11 road northbound, which means a smoother road surface, less noise and improved safety for drivers.
In early 2023, we started working on the southbound section.

How we’re working
We're doing the work in the following stages:
Stage 1: Installation of roadworks on southbound carriageway (complete)
Stage 2: Rebuilding the northbound A11 between Spooner Row and Tuttles Interchange at Wymondham (complete)
Stage 3: Rebuilding the southbound A11 from Tuttles Interchange at Wymondham to Spooner Row (in progress).
During stage 3a, the following slip roads will be closed:
- Spooner Row northbound entry slip
- Spooner Row southbound exit slip
- Browick Junction southbound exit and entry slip
- Tuttles Interchange southbound entry slip
Stage 3b: We will need the Spooner Row southbound entry slip road to be closed, and we will open the Tuttles Interchange southbound entry slip road so that local road users can access the A11 southbound. A full list of closed slip roads will be published closer to the time.
Stage 4: This will be the final stage, ahead of completing our work. During this time we’ll start to re-open all slip roads – more information relating to slip road openings will be made in due course. The following slip roads will be open though, from the start of stage 4:
- Spooner Row northbound exit slip
- Spooner Row southbound entry slip
- Browick Junction northbound entry and exit slip
- Tuttles Interchange northbound entry and exit slip
- Tuttles Interchange southbound entry slip
We are using a ‘contraflow’ system to keep everyone safe and the road open whilst we’re working. A contraflow is when the road is shut in one direction and traffic is then moved over to drive on the other side of the road to share the remaining road space. This provides us with a clear working area, which means we can work more quickly and safely.
By using a contraflow, the A11 can have one lane of traffic in each direction for most of the construction period. Full road closures are only be needed when we set up and take down our roadworks. The speed limit is temporarily reduced to 40mph for safety.
We’ve tried to keep local traffic on the A11 during the construction of the scheme, but this isn’t possible for safety reasons. We’ve also tried to find a balance in having long distance traffic on the A11, as well as local road users. Unfortunately, our roadworks will cause delays on both the A11 and on local roads during peak morning and evening times. We apologise for any inconvenience caused.
Please allow extra time for your journey. The maximum expected delay for traffic on the A11 between Spooner Row and the Tuttles Interchange during the construction will be an extra:
- 14 mins for traffic travelling northbound on the A11 during peak times
- 10 mins for traffic travelling southbound on the A11 during peak times
Unfortunately, some slip roads will need to be closed for long periods during construction.
We’re encouraging long-distance through traffic to use a route that avoids the A11 altogether, so that local roads have less congestion whilst we do our work. Instead, they will take a route along the A1066 and the A140 to bypass our roadworks.
We’re also continuing to talk with the local and wider community throughout the construction period, so that you can make decisions about your journey.

Diversion for long-distance traffic on A11
We’ve had to close some of the entry and exit slip roads between Spooner Row and the Tuttles Interchange for two reasons:
- Because we’re rebuilding the A11 southbound, and so traffic isn’t able to reach the slip roads during this time.
- Because we’ve reduced the A11 to one lane in both directions whilst we work. To keep the traffic flowing well, we need to close certain entry and exit slip road within the roadworks. Cars queuing on these slip roads or trying to join the single lane on the A11 will interrupt the traffic flow, and cause congestion within the roadworks.
There is a 40mph speed limit is in place for the safety of road users, and our workers. Our safety assessments show that 40mph is the highest, safest speed limit in roadwork.
We provide a free 24/7 recovery service within the roadworks. There are 23 cameras along the length of our roadworks that allow us to quickly identify stranded vehicles. These alert our recovery team, who then go to the vehicle and removing it via one of our access gates in the temporary barrier, and get them to a safer place.
Emergency vehicles are allowed to drive in our sectioned-off work areas, which allows them to quickly bypass any congestion when they’re responding to an emergency.
When complete, the scheme will:
- improve safety and provide a smoother rider for road users
- reduce noise levels
- create a new modern road with a 40 to 50-year lifespan that’ll be easier and quicker for us to repair in future
