An unfinished "Dutch-style" segregated cycle lane in Bristol has been labelled as "lethal and awful" by critics, including a visiting Dutchman.
The 700m (2,297ft) feature on Clarence Road has been beset with building delays of 18 months and damaged infrastructure from traffic.
It was due to cost £380,000 and some cyclists have claimed it is not safe.
Bristol City Council said it "accepted" the bollards had not worked and would replace them with "more robust kerbs".
In February 2014, when the idea was first announced, Bristol mayor George Ferguson said the scheme would be modelled on similar cycle ways from the Netherlands and Denmark where cyclists are considered to have the same rights as motorists.
Tourist Jon De Clein, who is visiting Bristol from the Netherlands, noticed the unfinished lane and said it did not offer a "safe feeling".
"It's not really the way we would probably organise it," he said. "It would probably have a bit more separation.
"I would probably feel safer if I cycled on the big wide footpath."
'Deadly for cyclists'
Dozens of people responded to a video of the route, posted on Facebook by BBC Radio Bristol, including Terry Owen who said he used it every day.
He listed positives including it being "marginally safer and more convenient" than cycling on the adjacent road, but criticised the bollards as "deadly for cyclists and motorists alike".
Also, Georgia Searson-Teague wrote: "I'm all for making things safer for cyclists but these little bollards are so dangerous.
"I walked past the other day and there was a car wedged on top of one at the end of the road."
Peter Mann, from the council, said replacing the bollards would cost "another £30,000" but as the scheme had come in under budget, they were not "out of pocket".
He said the bollards were "always an experiment", and that work to replace them should be completed by the end of November.
