Folk eager to see major changes to a main route in and out of the city have raised their concerns as to whether possible improvements will go ahead.
Families living near Sprowston Road have said they do not have "much faith" in Norfolk County Council's proposals to ease congestion and improve safety on Sprowston Road.
County Hall is still waiting to find out whether it might get cash for the project from the government's £32 million Transforming Cities Funding programme.
The council said plans in Sprowston Road could include widening the road and removing on-street parking.
Matt White of nearby Silver Road said: "Our area is in desperate need of improvements in walking and cycling infrastructure. Many people want to cycle, but simply don’t feel safe enough to.
"Pavements are frequently blocked with illegally parked cars, which limits rightful access for pedestrians and wheelchair users.
"While we await proper funding, I would like Norfolk County Council to implement cheaper measures like double yellow lines and controlled parking zones to make our streets more people friendly."
A spokesman for Norfolk County Council said: "We have made a request for an extension to the funding/delivery and we hope to hear the outcome soon, but no date has been given at present."
There is no timescale for the project's start and completion.
Cllr Alex Catt, Green representative for the Sewell ward, added: "It's disappointing to see this project in limbo.
"I hope Norfolk County Council push for this funding as a priority to improve the area for all."
Lucy Hall, of Living Streets Norwich, said: "Having cars regularly blocking footways, a shortage of decent crossings and speeding motor traffic makes life difficult for disabled and able-bodied people alike.
"Norfolk County Council needs to find a way to implement the improvements that residents have been asking for to make the roads safe and comfortable for all.
