With so much happening around Dublin city centre - there are a number of traffic restrictions around the capital this weekend.
Diversions will be in place around Merrion Square for the SuperValu Big Day Out and St Patrick's Festival FunFair.
Derek Ryan of AA Roadwatch said there will be a number of other areas for motorists to watch out for.
"Custom house Quay is closed until six o'clock on Tuesday morning for the Festival FunFair, with diversions in place on Dublin Bus routes 4, 9 and the 140 as a result of that," he said.
"Now from midday today until one o'clock there'll be restrictions in place around Dawson Street for the 5K road race.
"There'll also be restrictions in place on Merrion Row, Baggot Street, Fitzwilliam Square, Herbert Street, Herbert Place, Leeson Street Bridge, Grand Canal and Adelaide Road Earlsfort Terrace and St Stephen's Green."
