Donegal County Council has reopened two of the main road arteries on the Inishowen Peninsula and hopes to have a third one open by Monday.

A week on from devastating floods, preparatory work is ongoing on the Carndonagh to Quigleys Point road in advance of the army bringing up a "Bailey bridge".

This will allow the council to reopen one lane of the road while it works on a permanent bridge to replace the one wrecked by the floodwaters. 

The voluntary effort to assist people affected by the floods continues at a terrific rate. A depot set up in Buncrana to gather household and personal items has been overwhelmed with donations from all over the country and even from the USA.

Volunteer Susan Farren said they have been able to help at least eight families so far to make homes of the houses they have been allocated while their own homes are uninhabitable. 

A number of fundraising events have also been organised to support the flood relief efforts.

One of the main ones will be held in the Aura Centre in Letterkenny on Sunday afternoon next with country singers Daniel O'Donnell and Nathan Carter headlining a host of country stars. 

The council expects it could take at least between four and six months to complete repairs to roads damaged by the floods last week.

Speaking on RTÉ’s Morning Ireland, the council’s senior engineer Brendan O'Donnell said an inventory of the extent of the damage had been drawn up and presented to local councillors on Monday.

He said the next step was to consider what remedial works needed to be undertaken to fix the damage as well as costing, prioritising and resourcing the repairs.

Referring to the road between Quigley’s Point and Carndonagh where a bridge is down, Mr O'Donnell said the Defence Forces would be installing a temporary one-way bridge structure or 'Bailey bridge' by the end of the weekend which would allow the road to re-open to traffic.

As for Donegal County Council having sufficient funding for the repairs, Mr O’Donnell said the council was working on the basis funds would be available when they needed it.

"We're happy we have been liaising with the Department of Transport and while we haven't put a figure just yet to them," said Mr O’Donnell.

"We certainly have no indications that money is going to be a difficulty."

Many parts of the northwest suffered severe flood damage in last Tuesday night's freak rainfall.

Independent MEP Marian Harkin has said that an application should be made by Ireland for the European Solidarity Fund to assist with the clean-up operation in Co Donegal.

Ms Harkin said that she has already made contact with Minister of State with responsibility for Flood Relief Kevin 'Boxer' Moran and the European Commission about it. Mr Moran has said the clean-up operation is going to be enormous.

In a statement, Ms Harkin said that the fund was set up by the EU to assist member states in the aftermath of national or regional disasters. She said that Ireland has applied for the fund just once before - following severe flooding in Cork when €13 million was received in aid.

Ms Harkin said: "Each region has a damage threshold that must be exceeded in order to apply for aid. In the case of the Border, Midland and Western region, that threshold is €497.8m.

"As the estimated costs of the flooding are currently in excess of €400m it was highly likely that the affected area would qualify for aid, and I have therefore asked the Minister to start the ball rolling," she said.

Yesterday, Donegal County Council said that 47 families have so far registered as being displaced following the floods. 

It is likely that some families will not be able to return to their homes for some time, but the council says it is working closely with each family on a case-by-case basis.

Taoiseach Leo Varadkar visited the area last week and said that additional funding will be made available to Donegal County Council for repairs.

He also said a number of other humanitarian assistance schemes will be available to home and business owners and there will be a very strong Government response to support the people of Donegal.
