A ban on traffic on Capel Street, except for morning deliveries, is being planned by Dublin City Council.
The north city thoroughfare, along with Parliament Street on the southside, was the subject of trial pedestrianisation on weekend nights last Summer.
Surveys afterwards found that 89% were in favour of making Capel Street wholly or partially traffic-free.
A meeting of local councillors has been given a presentation on closing off Capel Street from Parnell Street completely, with deliveries only be possible from side streets between 6am and 11am.
The presentation entitled 'Traffic Free Capel Street' envisages a plan being presented in March and, depending on the results of consultation, a possible implementation by May.
A layout will have to be agreed with Transport Infrastructure Ireland (TII) because of the LUAS crossing at Abbey Street.
Traffic will have to continue to cross from Strand St Little to Strand St Great for a time due to construction works.
Access will also be required for the area's 2,200 residents.
Independent councillor Nial Ring said there are nearly as many vehicles - 8,795 - as there are pedestrians - 9,600 - using the street.
He said this plan would involve removing a massive amount of traffic, considering that 65,000 cars in total cross the canals each day.
It was not clear how to cross from the northside to City Hall if this change was carried out.
However, Green Party councillor Janet Horner said the plan is to bring more life to this part of the northside.
"We want Capel Street to become a vibrant hub and a destination for retail and hospitality and pedestrianising the street, as well as upgrading the public realm, is part of that," she said.
