Some 135,000 music fans are expected to attended the Robbie Williams concert in Phoenix Park next Saturday which promoters say will be the biggest open-air rock concert ever to take place in the State.
The concert will take place at Whitefields, near the Castleknock end of the park, from 3 p.m. to 10.30 p.m. with gates opening at 1 p.m.
The Garda this morning released details of a major security and traffic management plan to cater for the event.
All gates into the Phoenix Park will close to traffic at 11 p.m. on Friday night and will remain closed until Sunday morning.
People attempting to access Dublin Zoo, Garda Headquarters, Áras an Uachtaráin and other premises within the Phoenix Park are asked to use the North Circular Road Gate only.
However persons going to St Mary's Hospital and the Cara Cheshire Home can use the Knockmaroon Gate.
Gardaí are urging concert goers to use public transport to get to the event to ease traffic congestion. Dublin Bus will operate a shuttle bus service between Georges Quay in the City Centre and the Parkgate Street entrance to the Phoenix Park.
Dublin Bus will also operate an expanded Nitelink service on Saturday night after the concert.
Gardaí will mount a major policing operation in conjunction with this event to ensure the safety of those attending and to regulate traffic flow before, during and after the concert.
Gardaí are also warning that there will be parking restrictions on all approaches to the Park and illegally parked cars will be towed away.
Parking for private cars will be available at three locations - two in Castleknock (Castleknock College and Sommerton Car Park) and at the Irish Kennel Club at Cloghran, Swords. Private Coaches will be directed to park at Chapelizod Road.
Gardaí are advising traffic approaching from the North and North East along the M1/N1 will be directed to use the Park and Ride facility at the Irish Kennel Club, Cloghran.
Buses will take patrons from here to a drop off point close to the Cabra Gate, Phoenix Park.
Traffic from the City travelling outbound along the Navan Road will be directed to park at Castleknock College.
All other traffic should approach from the M50 and get onto the N3 (Navan Road) outbound where they will be directed to the car park at Sommerton. Signposts will be in place to assist motorists.
Private coaches approaching from the M50 should exit at the Palmerston junction where they will be directed to Chapelizod Road.
Gardaí are warning concert goers that they will not be allowed to bring alcohol or anything that could be used as an offensive weapon past the search points.
