Proposals to build a controversial new motorway through the Hill of Tara in Co Meath will be discussed in detail next week by the Oireachtas joint Committee on Local Government.
At issue is whether the proposed road should be built with or without a proper archaeological dig of the locality.
A number of experts will be questioned about the level of archaeology in the area.
Chairman of the Committee Sean Haughey TD has said that he is hopeful all concerned will have a say before a decision is reached.
He said that a number of archaeologists have already met the Committee in the last two weeks to outline their concerns about the site.
This week Dr Patrick Wallace Director of the National Museum and Dr Bernard Lacey of the Discovery Programme and various personnel from the Heritage Council will meet with the Committee.
