Black cab drivers have created traffic chaos for the second day in a row after they formed a blockade on London Bridge.
Angry drivers blocked the river crossing in both directions during the Tuesday's rush hour.
It is a part of a bitter protest against a Transport for London (TfL) scheme that would ban them from using a bus lane in a small section of nearby Tooley Street.
As roads were plagued by further backlogs of traffic on Tuesday evening, TfL blasted the action as "unnecessary".
Dubbed the "licensed taxi protest", drivers have promised to protest each day until Friday between 4pm and 7pm. They staged their first protest on Monday night.
Posters for the protest claimed the drivers have been "discriminated" against and that they have suffered "injustice".
One of the drivers said the proposed changes to Tooley Street could have implications for people trying to reach London Bridge Hospital, which is on the street.
But the London Cycling Campaign Group has charged the cabbies of trying to "derail" the "creation of a safer and healthier Tooley Street."
Ben Plowden, TfL's director of strategy and network development, said in a statement: "A consultation is currently underway on Tooley Street's changes to improve the conditions for people walking and cycling, or traveling by public transport.
"The best way for people to let us know what they think about these proposals is to respond to the consultation, so this type of protest is unnecessary.
"All feedback on our proposals will be thoroughly assessed and taken into account."
The consultation for the Tooley Street scheme runs until January 9th, with TfL insisting no decision will be made until all responses are considered.
