The £1m revamp of a roundabout close to the Norfolk and Norwich Hospital has been branded "extremely dangerous" as work nears the halfway point. 

Access roads along Colney Lane, which provide access to the hospital and research park, are being restructured as part of a six-month project to improve traffic flow. 

But members of the Norwich Cycling Campaign have slammed the scheme for severing an important cycle path over the roundabout junction, which will force them to make unsafe crossings.

"There is ample land available for building full, three-metre-wide, shared-use cycle tracks with a buffer strip between them and the road."

A County Hall spokesman previously said the cycleway is being retained but there will be "pinch points" in the route once the revamp project is completed.

"The road carries a lot of traffic, the hospital being the main destination for many users of the junction," the spokesman continued.

"Having 'informal' crossings on three arms of the junction is extremely dangerous, especially when the junction arms have been widened to speed up general traffic.

"These should instead be parallel crossings or light-controlled toucans."

"The scheme isn't being built for the hospital, its purpose is to increase traffic access to the Research Park through the hospital grounds, which is odd because the Research Park has its main entrance off Hethersett Lane," the spokesman added.

"All this will do is add congestion to the access road to the hospital, which includes the A&E department and emergency access."
