A business group is asking organisers of a protest against water charges to change tomorrow's route.
Demonstrators will gather at 1PM at Heuston, Connolly and Merrion Square before marching to O'Connell Bridge.
Richard Guiney from DublinTown.ie reckons the routes have been designed to cause maximum disruption.
Trade Unionist Brendan Ogle from the Right2Water group said he expects thousands of people to turn out.
