Pope Francis travels a considerable distance this weekend through the center of Dublin in his Popemobile, a projected crowd of around 100,000.
On Saturday afternoon, the general public will mark the first opportunity to see Pope Francis, according to assistant Garda Commissioner Pat Leahy.
Mr Leahy said that the public journey will take place after the Pope has finished in Pro Cathedral at 4.15 pm.
The route goes south on O & # 39; Connell Street, on the O & # 39; Connell Bridge, on the Westmoreland Street and on the Dame Street.
The route then passes Christchurch Cathedral, exit Bridge Street and cross the Liffey to Church Street to the Capuchin Day Center where he will meet homeless people and families.
It is not known how many security guard vehicles and personnel will accompany the motorcade, as Gardai refused to discuss details for safety reasons.
Gardai said that they expect a maximum of 100,000 people in the city center to view the motorcade and that AA Roadwatch has outlined a number of traffic restrictions.
They have urged everyone to travel to Dublin on the weekend to take public transportation as there is no parking near Phoenix Park.

They also warned everyone without a ticket for the events not to travel to Croke Park, Knock or Phoenix Park.
Arwen Foley of AA Roadwatch said: "Planning is the key this weekend.
"Additional services will become available in all public transport networks and we strongly encourage people to use them."
She said: "The full length of the M50 and the M1 is normal, so once on the highways there is no problem to travel to Dublin Airport.
"The Port Tunnel and Tom Clarke Bridge (East Link) will also be open, so anyone who wants to travel between the north and south of the city is advised to use these routes."
There are specially designed park and ride hubs at Leopardstown Racecourse, UCD Belfield and Maynooth University.
Most of the road closures in Dublin will be on Sunday, because Pope Francis will be the most important celebrant at the last Mass in Phoenix Park at 15.00.
There are big limitations around Phoenix Park, which stretch for a few kilometers in the center of the city.
