The £4m revamp of one of Norwich's busiest roads has been branded a waste of money which "will lead to traffic congestion and resentment".
Work which will bring major changes to Dereham Road, between Longwater Lane and Gurney Road, is due to begin at the end of next month.
Norfolk County Council's plans, which were given the go-ahead in January, include new bus lanes, wider pavements and crossings.
The speed limit between Longwater Lane and Norwich Road is due to be cut from 40mph to 30mph as part of the proposals.
But the multi-million-pound scheme has been branded a waste of money by one of the councillors representing the area it covers.
Mike Sands, Labour county and city councillor for Bowthorpe, said: "The scheme, other than the cycleway, is not needed and represents a complete waste of money.
"The bus lane extensions not wanted or needed, the surface crossing at Wendene not needed, the bus cut through across the central reservation not needed.
"The whole proposal will lead to traffic congestion and resentment."
He said what the community really needed was an extension to the 23 bus route so it runs between Bowthorpe centre and the shops at Longwater.
He said: "That would be an improvement to local transport and at marginal cost, not the millions mooted."
Gary Blundell, Liberal Democrat councillor for New Costessey on South Norfolk Council previously questioned the 24-hour bus lanes.
He said: "Bus lanes are important but it seems like a waste having a 24-hour one."
The scheme is being paid for using a slice of the £32m Transforming Cities Fund money awarded to the county council by the Department for Transport for a string of schemes in and around Norwich.
Council officers have said the bus lanes will improve bus journey reliability and point to modelling which suggests they would only have a "minor" impact on other traffic.
But they have said if the scheme produced any "unforeseen issues" a review could take place.
