Castle Street - which links Kingston Train Station with Clarence Street - is set to receive a face-lift if proposals for its pedestrianisation go ahead.
The street, currently a busy road dominated by parked cars, could be transformed into a pedestrian-friendly street lined with trees and outdoor eating areas.
Kingston Council wants residents and business to give feedback on the proposals.
They include no traffic or parking in Castle Street, apart from limited access to service vehicles. A new loading bay using automatic barriers would be created at the Fife Road junction with Castle Street.
There could also be outdoor caf seating, a two-way cycle route, new paving, trees, granite benches, bins and stainless steel street furniture.
Councillor Chrissie Hitchcock, chairman of Kingston Town neighbourhood committee said: "Castle Street should be a gateway to Kingston, offering a welcome to the thousands of people who travel there by train every day.
"We have an opportunity not only to change the way Castle Street looks, but also to alter radically the way it is used. Thanks to funding from Transport for London, the London Cycle Network, Kingston First and developers such as The Rotunda, the new Castle Street could become an oasis of calm; a relaxed and pleasant environment in which to shop or stop at one of the road's many cafs."
The Castle Street project is part of the council's K+20 initiative, which aims to involve residents and businesses in designing the future for Kingston Town Centre.
A leaflet providing full details of the proposals, along with a feedback questionnaire, is available from Guildhall II reception or www.kingston.gov.uk. There is a small exhibition on the proposals in the Market House and Kingston Library.
