The Lansdowne Road stadium is to reopen in April 2010
The rebuilt Lansdowne Road will be called the Aviva Stadium following a deal reported to be worth 40 million Euros to Irish rugby and football.
The 50,000-seat venue in Dublin is to reopen in April 2010 and host the final of the revamped Uefa Cup in 2011.
During the rebuilding, the Irish rugby side and the Republic of Ireland football team have played their matches at the GAA's Croke Park ground.
The deal with insurance firm Hibernian Aviva is to run for 10 years.
"We believe that in the difficult economic conditions we are going through, Aviva Stadium will be of huge benefit to the economy as a whole," said Philip Browne, chairman of Lansdowne Road Stadium Development Company and chief executive of the Irish Rugby Football Union.
"Even taking the most conservative view, I do not think it would be exaggerating to say that Aviva Stadium could have an impact of some 250 million Euros on the local economy each year."
