Dublin city councillors have defied a direction from the National Transport Authority (NTA) to preserve lands for an eastern bypass across Dublin Bay in the new city development plan.

However, the council’s law agent Terrence O’Keefe warned that the removal of references to the bypass from the plan was “illegal”.


Last month, the NTA published its 20-year strategy for the greater Dublin area which includes a plan to develop the first section of the route, from the port tunnel to the south port area, and the retention of a “route corridor” from the docklands to the “southern cross/southeastern motorway” – the meeting points of the M50 and the M11.

Council management said that, as a result, it was compelled to amend the development plan to take into account national policy.

A new objective in the plan would “protect the route of the proposed eastern bypass... and for the longer term to retain a route corridor between Poolbeg and the southern cross/southeastern motorway via an eastern bypass of the city”.

Green Party councillor Ciarán Cuffe, who proposed one of eight motions against the bypass, said it would cost €4 billion and “effectively sterilises at least 50 hectares of land that could provide for 2,500 housing units within close proximity of the city centre, and could encourage further car-based commuting to the city”.

Labour’s Dermot Lacey said the council had “consistently voted against” the eastern bypass. “I don’t care that an unelected quango has decided an eastern bypass is right for Dublin, I believe it is wrong for Dublin,” he said. “Eastern bypass is a word officials have used for a road over and on top of Sandymount strand.”

Independent Paul Hand said a lot of housing or other transport infrastructure could be built for €4 billion instead of “effectively building a tunnel under Dublin Bay – a Unesco biosphere”.


Meanwhile, councillors are expected to vote to block plans to increase the height of apartment buildings that can be constructed in the city.

City council chief executive Owen Keegan wants to allow apartment blocks up to 28m tall.

However, all councillors except Sinn Féin and several Independents are seeking to restrict the height of residential developments.
