Plans to close the central section of The Cut to through motor traffic are being drawn up by Lambeth and Southwark councils in conjunction with Transport for London.
The scheme is part of Transport for London's plan to develop "low-traffic corridors" in central London to discourage the use of motor vehicles during the recovery from COVID-19.
The section of road to be closed forms part of the borough boundary, with the northern half of the carriageway in Lambeth and the southern half in Southwark. The road closure scheme is being led and funded by Lambeth Council.
Southwark Council's backing for the scheme is expected to be signed off by Cllr Richard Livingstone in the coming days.
The principle of closing The Cut to through motor traffic has been trialled this year, with the road blocked between January and July at its eastern end whilst Thames Water repaired a burst water main.
Southwark Council said that "the need for rapid intervention before traffic levels increase to an unacceptable level has been identified".
