It will take 100 years to repair road defects in Dublin city because of inadequate funding, according to an official council report.
The report warns that the city's 1,250km road network is already deteriorating faster than it can be repaired.
Just under half the city's roads are in need of repair with 11% or 27km in need of "structural restoration" or "reconstruction", according to the report by Dermot Collins, assistant executive manager with Dublin City Council.
However, his report points to a financial shortfall of nearly €6m since central government funding was replaced by property tax income, which Dublin has to share with other local authorities.
Construction costs have also risen by 50% since 2011.
Mr Collins states that it is "imperative" for the city council to receive more investment.
The report states that only 70% of defects and hazards are currently being repaired with increased construction traffic and underground utility works adding to the problem.
The under-investment will result in more personal injury claims and vulnerability for the increasing numbers of cyclists and pedestrians, according to Mr Collins.
Chairperson of the council's finance committee, Seamas McGrattan (Sinn Féin), said there is a "huge gulf" in funding for roads in urban areas compared to the bigger sums of money spent on rural roads.
Cllr McGrattan said part of the problem is that many roads in towns and cities are not classified as national or regional roads and do not qualify for national of EU funding.
He also called for Dublin to be allowed to keep its property tax income as promised in the current programme for government.
