The Tánaiste has asked his officials to look at eight road projects which have been stalled, to determine which need to be prioritised "for business and enterprise".
Leo Varadkar said he will engage with Transport Minister Eamon Ryan once he knows which of the projects are the "most valuable economically".
He told the Select Committee on Enterprise that he is being contacted by "people all over the country" who are concerned about the issue.
"We need roads to access housing, and roads to access IDA sites", Mr Varadkar said.
His remarks come amid reports of rising tensions between coalition partners Fine Gael and the Green Party over a number of issues, including roads.
The Tánaiste was responding to party colleague David Stanton, who welcomed his comments.
Deputy Stanton said the Department of Transport had decided not to fund road access to an IDA-owned site in his constituency of Cork East.
"It is 56 hectares, fully serviced", he said, and lies on the the N25 Carrigtwohill-Midleton road, which "isn't up to standard".
He said the Department of Transport has decided not to continue with upgrades to the N25.
"It beggars belief", Deputy Stanton said, adding that the decision has left the local authority "totally perplexed".
The site "has been sitting for twelve years", he noted.
Deputy Stanton said that he has written to Minister Ryan, and raised the matter in the Dáil, but has yet to get a response.
In a wide ranging session, the Tánaiste also said that employers are reporting that "labour shortages are definitely a major issue".
There is a "very significant backlog in work permits" following a "surge in applications", he said.
But Mr Varadkar told the committee that he has been assured by his secretary general that there will be "a big improvement over the next couple of months".
He also cautioned the committee that we "have to be wise to risk of a further serious wave of Covid", while adding that he does not think it will occur.
The Government hopes that there will be 400 remote working hubs by the end of the year, he said.
The Tánaiste also said that we will "see a slow down in the number of data centres being connected, particularly around Dublin".
Mr Varadkar emphasised that "we need to produce a lot more electricity in Ireland", and to do so from renewable sources.
"Data centres would be of a lower priority than homes, or hospitals" for connection, he added.
He was responding to Sinn Féin TD Louise O'Reilly, who noted that data centres currently use around 11% of electricity in Ireland.
She asked how increased electricity use by data centres and climate change goals can be squared.
"It can only square if the electricity used is green", Mr Varadkar said.
