Improving the pedestrian link between Lynn railway and bus station will see Waterloo Street closed to through-traffic.
Traffic would still be able to use the street for access and there would potentially be a residents parking permit scheme.
That is if current West Norfolk Council proposals are approved and dependant on a separate consultation on parking permits.
Victoria Hussain, of St John’s Terrace, Blackfriars Road, sometimes uses Waterloo Street for parking.
She said: “I am really pleased they are doing something to improve that road because obviously it is the natural way people walk through but parking is an issue and we just struggle with it so much.
“They are turning a lot of the houses long here into flats and that means more cars, but there is no amenity for parking.”
A resident of Waterloo Street, who did not want to be named, said: “I can’t help but think the only way to really improve things would be to take cars out of the street altogether – the parked cars at least.
“It ought to be pedestrianised apart from deliveries and emergency vehicle access.
“I don’t know how they’ll enforce the ‘access only’ rule. It has never been achieved at Littleport Terrace, which cars still use as a through-route.”
