View details of work and traffic management from 2 January 2018

Norfolk County Council and Norwich City Council are improving the junction where Dereham Road, Sweet Briar Road and Guardian Road meet.

The aim is to reduce congestion at the junction for all traffic, improve pedestrian crossing facilities in the area and provide a better environment for cyclists.  By providing a more efficient junction, the project also aims to improve reliability and journey times for bus services on Dereham Road.

Details of work:

  • Increasing size of the existing roundabout, including widening of the carriageway, mainly towards the allotment side.
  • New embankments, kerbing, drainage, street lighting and road signage.
  • New signal-controlled crossings on Dereham Road (by the Gate House public house), and also on Guardian Road (on the approach to the roundabout).
  • Footways resurfaced and, where possible, widened.
  • Diversions to underground utility cables to allow the road widening – some of the preparatory work is already underway.
  • Surfacing of the carriageway at the roundabout and on its approaches, including repairs to the existing carriageway.
  • Some clearance on the two allotment sites will take place in August to prepare the work areas and set up site compounds.
  • Tree removal work will be carried out overnight during a two-week period in September, with some further clearance in November.
  • Replacement tree planting and improvements to the allotment sites. 

Reasons for work:

  • Improve reliability and journey times for buses.
  • Improve flow of general traffic.
  • Improve the capacity of the roundabout so it can cope with any future increase in traffic levels.
  • Provide better crossing facilities for pedestrians and cyclists.
