An iconic bridge on the M1 motorway near Drogheda has officially been renamed the Mary McAleese Boyne Valley Bridge.
The decision to rename the cable bridge after the former president was taken by Louth and Meath Councils to honour her work in the peace process.
"Building Bridges" was the theme of the McAleese presidency, reaching out to both communities in Northern Ireland.
The event was attended by former paramilitaries and politicians as well as representatives from various unionist groups such as the Orange Order and Royal Black Preceptory.
Speaking at the ceremony, Taoiseach Enda Kenny praised the work of Mrs McAleese and her husband Martin.
Mrs McAleese said she had always admired the iconic bridge and added that it was poignant to be gathered at the Battle of the Boyne site with many who were once enemies.
She said she was privileged to be one of those who helped build the peace process.
