Up to 30,000 people are expected to turn out for the State funerals tomorrow.

Roads in parts of Dublin will be sealed off to traffic for several hours as the men's remains are transferred from Mountjoy Prison to the Pro-Cathedral and then to Glasnevin Cemetery for reburial.

The remains of the men, tried and sentenced to death by military court martial in 1920/1921, have already been exhumed from the grounds of Mountjoy Prison.

The President, Mrs McAleese, every member of the Oireachtas and almost 600 relatives of the men are among 1,000 people invited to the Mass at the Pro-Cathedral by the Taoiseach, Mr Ahern.

The leaders of the Opposition parties will attend the event, despite their accusations that Fianna Fβil "hijacked" the funerals by holding them on the same weekend as the party's ardfheis. The party has rejected these criticisms and insisted that the timing of the event was coincidental.

The Garda Traffic Section said up to 30,000 people are expected to line the route the cortege will follow, and 2,000 people had been invited to attend the ceremony at the cemetery.

The proceedings will begin around noon with a private prayer service at Mountjoy Prison attended by about 100 relatives nominated by the men's 10 families. Prison officers will form a guard of honour as the cortege including 10 hearses and 10 mourning cars begins its journey at 1 p.m. to the Pro-Cathedral on Marlborough Street, led by an Army motorcycle escort.

It will travel through Phibsborough Road, Broadstone, Constitution Hill, Dame Street, College Green and Westmoreland Street. These routes will be closed to traffic between approximately 1 p.m. and 1.30 p.m. The rest of the 600 relatives will assemble at Dublin Castle and form up behind the chief mourners and family pallbearers at Westmoreland Street before proceeding in a slow march to the GPO.

The cortege is due to arrive at the GPO at 1.20 p.m. where a lone piper will play a lament at a brief ceremony. The mourners will then proceed to the Pro-Cathedral where a Requiem Mass is scheduled to begin at 2 p.m.

A limited number of members of the public will be accommodated in a covered area in the Pro-Cathedral courtyard, on a first come first served basis. Access to the courtyard is via Cathedral Street and no admissions will be allowed after 1 p.m.

Cardinal Cahal Daly will be the chief concelebrant at the Mass. At about 3.30 p.m. the cortege will set off to the cemetery, joined by Mrs McAleese, Mr Ahern, the Tβnaiste, Ms Harney, other members of the Cabinet and the Council of State.

It will stop briefly at the Garden of Remembrance on Parnell Square where a minute's silence will be observed. The route to the cemetery will be via North Frederick Street, Dorset Street, Whitworth Road, Prospect Road and Finglas Road.

The Taoiseach will give a graveside oration before the reinterment of the remains of nine of the men in a memorial plot. The remains of the tenth man, Mr Patrick Maher, will be brought to Ballylanders, Co Limerick, for reburial on October 20th in accordance with his family's wishes.

No traffic will be allowed on the Finglas Road during the interment. Members of the public who wish to attend the ceremony in Glasnevin Cemetery are advised to enter via Bell or Violet Hill Gates.
