Why we need this scheme

The A47/A11 Thickthorn junction is important for commuter, business and commercial traffic, on both short and long-distance journeys.

Committed developments in Cringleford and Hethersett are expected to increase traffic demand at Thickthorn junction and the A11/Round House Way junction significantly by 2026. With no significant junction improvements, demand is expected to exceed capacity at both locations. Increased congestion in future years is likely to constrain economic growth in Norwich and South Norfolk and reduce user satisfaction.

Approximately 3,000 new residential dwellings are potentially planned near the interchange along with commercial units. Once completed this will exacerbate congestion on the junction and increase stress on the road network.

Aims

The aims and objectives of the A47/A11 Thickthorn junction scheme are to:

  • contribute to sustainable economic growth by supporting employment and residential development opportunities
  • reduce congestion-related delay, improve journey time reliability and increase the overall capacity of the A47
  • increase the resilience of the road in coping with incidents such as collisions, breakdowns, maintenance and extreme weather
  • increase the reliability of the junction, reducing journey times and providing capacity for future traffic growth
  • consider local communities and their access to the road network, providing a safer route between communities for cyclists, pedestrians, equestrians and other non-motorised users

The scheme in detail

The scheme will help relieve congestion at Thickthorn junction by providing 2 new free flowing link roads that will connect the A47 with the A11. The new roads will re-route traffic away from the junction and flow under 3 new underpasses.

We will remove the existing footbridge over the A47 and provide a new footbridge for walkers, cyclists and horse riders.
