Spain unveils 17 bln euro infrastructure roadmap

 MADRID, April 7 (Reuters) - Spain unveiled a 17 billion euro ($22.7 billion) infrastructure spending plan on Wednesday, looking to attract private investment to boost its construction sector as it struggles with high unemployment and a huge budget deficit.

The government said 20 percent of the funds would come from the private sector and 80 percent from the Instituto de Credito Oficial (ICO), the European Investment Bank (EIB) and commercial banks.

Spain's largest public-private initiative ever will help maintain public works tenders without the government spending a cent as it cuts spending after its public deficit reached 11.2 percent of gross domestic product (GDP) in 2009.
