The European Commission, the executive arm of the European Union, has approved 3 billion euros ($4.1 billion) in financial aid to help build four major highways in Greece.

Construction on the highways has been halted over the past few years as the country has grappled with a severe debt crisis that's required big budget cutbacks.

Johannes Hahn, the commissioner for regional policy, said the investment is "central to the country's economic recovery" and forecast that building the highway will create 6,000 jobs. Of those, 1,700 will be long-term involving the management of the highways once construction is finished by the end of 2015.

Hahn said the highways form part of a trans-European road network and are essential for creating a single market for European goods.
