DUBLIN City Council has been given permission to build a €15m public transport bridge over the Liffey.
But the Marlborough Street bridge will only go ahead if Metro North gets planning permission and the Government decides to approve the multi-billion euro light rail system.
The Department of Transport, which will fund the project, said work on the new bridge linking Marlborough Street and Hawkins Street would only begin once Metro North is approved by the Cabinet.
The planning application for Metro North, which is with An Bord Pleanala, says that the Marlborough Street bridge will be used to reduce traffic congestion in the city centre when construction works begin.
It will take 18 months to build and cost €15m.
