THE €13.5m Rosie Hackett Bridge across the Liffey opened to the public today.
Buses, cyclists, pedestrians and taxis will be able to use it from 6am following its official opening yesterday.
It is named after a pioneering women’s rights and trade union activist involved in the 1913 Lockout and 1916 Rising.
She died in 1976.
A large crowd turned out on Marlborough Street for the occasion including members of Rosie’s extended family.
Dublin’s Lord Mayor Oisin Quinn and Transport Minister Leo Varadkar, helped by Rosie’s nephew John Gray, unveiled a plaque and cut the ribbon.
“The 21st Liffey bridge is a bridge fit for the 21st century. The first named after a woman,” Mayor Quinn said.
“Tomorrow at 6am we can say meet me at the Rosie and by bike, bus or brogue we can mosey across the Rosie’,” he quipped.
Mr Varadkar said the 1916 Proclamation was a “radical document and begins with words that were radical for its time: Irishmen and Irishwomen”.
He added: “It recognised the struggle for Irish freedom was shared by all of its people, men and women alike.”
But one of the young students who began the Rosie Hackett naming campaign noted that all the speakers at the event were men.
“The launch has been brilliant .. but it’s funny that we (women) had no speaking rights today. If you noticed, it was five men who were speaking,” Angelina Cox (23) said.
Dublin City Council’s director of traffic Michael Phillips told The Herald the new public transport crossing will speed up bus journeys by relieving pressure on O’Connell Bridge.
Mr Gray said he and the rest of Rosie’s family are “very proud that she’s being honoured”.
