A scheme to make a street safer for cyclists, dubbed a 'shambles' after tree roots scuppered the original plans, today came under fire yet again - because speed bumps installed just months ago have had to be replaced.

Norwich City Council had trumpeted the £785,000 changes to The Avenues as an important plank in its £5.7m Push The Pedalways project, which aims to make it easier for cyclists to get around the city.

But, last year, it emerged that original plans for dedicated Danish-style cycle lanes had to be scrapped. The council said 'detailed design work' established the only way to prevent the work for those from damaging tree roots would be to dig the paths by hand - which would make the cost of the scheme 'prohibitive'.

Instead, advisory cycle paths were painted on the road, to the disappointment of the Norwich Cycling Campaign. And now, it has emerged contractors Tarmac have had to return to the road to replace the road humps and repair road surfaces. The work started on Monday last week and was completed this Monday.

Just as in the case of another of the Push The Pedalway projects - Tombland and Palace Street, where repairs needed to be done not long after work was completed - the contractor has agreed to make the changes at no extra cost to the council.

A spokeswoman for Tarmac said: 'We're disappointed that these issues have occurred and regret any inconvenience this has caused for our clients and the public.'

Charlie Ringwood, who lives in nearby Bluebell Road, said: 'It's been chaos since they started on this road. They have caused so much upset and spent so much money on it, but it has been a shambles. It's been a mess since day one.'

And Bert Bremner, Norwich City Council's cabinet member for environment and sustainable development, said: 'We are very disappointed that Tarmac has had to replace the newly-laid surface and road humps in The Avenues, particularly following the recent need to resurface Tombland and Palace Street.

'Tarmac has once again responded quickly and carried out the work at no cost to the council. Obviously, we are unhappy that this has caused disruption for residents and those using the area.'

Work is also being carried out on the verges along the road. The council says that will improve parking, with road chippings on driveways and permit parking bays. The council aims to ban parking on marked, newly seeded grass verges.

That work is due to be finished in March.

The project was part of changes to an eight-mile Norwich cycle route, known as the pink pedalway, stretching from the Norfolk and Norwich University Hospital and the University of East Anglia to Heartsease and Broadland.
