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.
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
Thickthorn Interchange is located on the south-western edge of Norwich at the intersection between the A47 and the A11. The A47 connects Norwich and Great Yarmouth to the Midlands via King‚Äôs Lynn and Peterborough. The A11 is the main route connecting Norwich with Cambridge and London (via the M11 and A14). The interchange is connected through a gyratory which splits the A11 South from the A11 North, the A47 travels across the gyratory in a west to east direction.
The scheme consists of constructing two link roads connecting A11 South to A47 East via three underpasses (under the A11, the A47 westbound and the A47 eastbound). This does impact the side roads and two additional options are being considered to ensure access is maintained to Cantley Lane South. The existing footbridge over the A47 will be removed but accessibility of non-motorised users either side of the A47 is still being considered as part of the design.
