Norwich drivers have been urged to watch carefully for cyclists after one woman died and another rider was seriously injured in the city within 24 hours.

One woman in her 60s died in Newmarket Road on Sunday after a collision with a red Renault Laguna, while another cyclist was seriously injured at the Kett's Hill roundabout this morning.

The Kett's Hill crash came less than a fortnight after it had fully reopened following work costing £64,000 to supposedly make it safer for cyclists and pedestrians.

Following the crashes - the causes of which are still to be determined - Norwich Cycling Campaign's Derek Williams said the situation on city roads was "unbelievable".

He said: "It's now five incidents this year, I can't believe it.

"Most drivers are careful and conscious of cyclists but sometimes people get distracted, often by phones.

"It only takes a little lapse in concentration and it can cause a lot of problems.

"On the other hand, you have some people who are simply terrible drivers, I'd go so far as to say they are psychotic."

Mr Williams said the most common way bad drivers cause danger to cyclists on the streets of Norwich was by not leaving a gap when overtaking.

He added: "It's a bit like a punch in the backside when some of them go tearing past.

"The majority of drivers overtake carefully and give plenty of room, but a large minority don't and they're the ones who cause the problems."

Mr Williams said Norfolk County Council needed to install more purpose-built cycle tracks on the road in order to improve road conditions for those on two wheels.

He said: "It's a stupid culture war from central government which is causing a lot of the aggressive driving, this whole thing about a war on cars.

"The city can't handle the amount of traffic it sees at the moment, we need proper infrastructure and enforcement for those who drive dangerously.

"They've spent all that money on Kett's Hill and didn't build a cycle track, this was done under the Developing Cities fund which is supposed to improve things for cyclists but there is nothing there at all it's just pavements.

"It's a whole different world abroad. In Holland, where they have proper infrastructure, you see about 60pc of journeys made by cycle."

Mr Williams said the cycling campaign sent its "deepest condolences" to the family of the cyclist who died.

Anyone with information about the two recent crashes is urged to contact Norfolk police on 101.
