There have been warnings about delays and diversions as a leading garda that outlined the route of Pope Francis for the first time today by Dublin.
It is expected that 100,000 people will be taken to the streets to see how Pope Mobile travels through the capital this weekend, assistant Garda Commissioner Pat Leahy.
Pope Francis will arrive in Dublin on Saturday and pilgrims from all over the world will come to Ireland for the World Meeting of Families, including 500,000 who will see his address in Phoenix Park.
Today, with Miriam on RTE Radio One, Gda Leahy spoke about the Pope's journey through Dublin.
He said: "The Pope will visit the city center around 4:15 pm on Saturday when his pastoral visit in and around the Pro Cathedral is completed.
"He is going to make a Pope Mobile visit through the city, right above O & # 39; Connell Street, over O & # 39; Connell Bridge, all the way up through Westmoreland St and Dame St in Pope Mobile.
"This will be the first real opportunity for the public to see the Pope, he will then go up to Christchurch, to Bridge St, to Church St and to Brother Kevin in the Capuchin Center."
He stressed that the city does not get stuck, but said that there will be some unavoidable delays.
"The M50 is open on both days, there will be some restrictions on the Sunday where you will not pass, but in general the M50 is open to companies.
"The harbor tunnel is open to companies, the East Link is open to companies …
"We will facilitate people to move as much as possible when it is safe, the city is not stuck, but when we move half a million people to that zone, it becomes unsafe to stop traffic in that mix," said Mr. Leahy.
Up to 100,000 people are ready to watch Dublin's Pope Mobile ride and Mr Leahy continued to emphasize the size of the event and the schedule spent on the two-day visit.
"It's probably one of the two top events that I've been working on in my 36 years – the queen's visit is probably number one because of the security context around it, but this is definitely number two.
"In terms of the number of people this is certainly number one, it is difficult to imagine how half a million people in one place will look like, this is a huge event.
"We always have a structured response to security, a layered approach, what we will discuss this morning is how we bring people safely inside and out, half a million people," explained Leay.
"We expect a slow burn-in, with people who arrive more than a couple of hours and they will probably relax and chat and rest, but once they have arrived, they just want to leave and come home.
"So what we ask people is to apply the same concept when you leave, take your time, it will take time to go to your bus.
"We advise people that they now have their tickets to know that they have a color code and to follow the color-coding system on your ticket, because that will take you to the point where you will sit or stand at the event, but it also you return with your transport on the way back. "
When answering questions about the plans for taxis, he urged the drivers to contact the national transport authority in advance.
Pope Francis said Tuesday that he & # 39; excited & # 39; is to return to Ireland after having been here before in 1980.
He said in a special video message: "I know a lot of people are working hard to prepare for my visit and I thank them all from my heart, I ask everyone to pray that this great festival will be a moment of joy and serenity , a caress of Jesus tender love for all families, and indeed for all of God's children. "
Following Pope John Paul II when he visited Ireland in 1979, Pope Francis added: "Young people are the future."
