City centre roads in Sheffield - including the central Pinstone Street - are set to be turned over permanently to pedestrian zones under a radical overhaul.
It would also see traffic barred from Leopold Street and Surrey Street, with other changes made for cyclists, those on foot and passengers who use public transport.
The aim is to make journeys on foot and bicycle quicker, while streamlining public transport services in the city centre, according to Sheffield Council.
They have to consult with the public before making a decision on the scheme, but say changes would also include injecting more greenery into the city centre to make it a more pleasant place.
Cash for the work would come via the Sheffield City Region, headed by Metro Mayor Dan Jarvis, from a government fund.
Further projects are expected to follow, financed the same way, to be tagged under a new 'Connecting Sheffield' brand.
Changes to roads in the city centre were first introduced to provide more pedestrian space as the coronavirus pandemic struck but this project is aimed at promoting sustainable transport, cutting congestion, improving air quality and working against climate change.
If the plans proceed, they will have to be completed by 2023 to qualify for the government money.
Changes include installing bus gates in both directions on Furnival Gate and one way on part of Arundel Gate.
Rockingham Street would also get a new bus 'hub' with space found for a pocket park.
Council transport spokesman Cllr Bob Johnson said: “We are excited to start the conversation on the city centre improvements. We need to start planning for the future of travel, and to do this, changes need to be made.
“We have already seen some of the benefits of the proposed changes through emergency active travel measures earlier in the year, which include the closure of Pinstone Street so a lot of people have already had some experience of how the scheme could work. I’d like to encourage everyone to feedback their views as part of this consultation.
“We recognise that whilst there are a lot of positives to what we are proposing, there may also be some concerns. We keen to hear from as many people as possible, so please let us know what you think and ask any questions you have.”
Consultation runs until January 7.
