500 jobs are to be created due to the construction of new motorway service areas along the M1 and M4.

The total cost of the projects is €47m.

The three service areas will operate 24 hours a day.

Two will be located on the M1 - at Castlebellingham, Co Louth and at Lusk Co Dublin - and one on the M4 at Enfield Co Kildare.

The NRA said the service areas would be funded by a Public Private Partnership, the consortium consisting of Applegreen, TOP Oil and Pierse Contracting (Design & Construction).

Each of the service areas will provide facilities on either side of the motorway and at each location there will be a restaurant, convenience shop, toilet and showers facilities, fuel, and dedicated parking for HGV's.

Additionally, there will be child play areas, picnic areas and tourism information.

Asked by RTÉ News why other motorways would not secure service areas, an NRA spokesman said they would be built when finances allowed.
