The World Bank agreed on Tuesday to help Bulgaria develop its road and rail infrastructure by helping it come up with projects liable to obtain European Union funds, officials said. World Bank President Robert Zoellick and Prime Minister Boyko Borisov signed a memorandum of understanding to step up development of 'infrastructure including accelerating maintenance and investment in roads and railways.' 'We have probably the worst infrastructure in the whole European Union,' Borisov remarked, pledging to use World Bank and EU funds to build around 60 kilometres (around 40 miles) of motorway a year by the end of his term in 2013. Bulgaria has only about 400 kilometres of motorway and none of its border-to- border transport corridors is fully finished. Zoellick and Borisov declined to mention any financial terms of their agreement, but Zoellick said the World Bank had so far invested 1.5 billion dollars (1.1 billion euros) in projects in Bulgaria and had another 300 million dollars (229 million euros) of loans to be disbursed. 'Bulgaria has access to another seven to 10 billion euros (nine to 13 billion dollars) of (European Union) grant money, not loans, and it has only been able to tap about seven or eight percent of that,' Zoellick said, vowing to send experts to help boost project preparation and management capacity. Since it joined the EU in 2007, Bulgaria has had millions of euros in EU aid frozen by Brussels, because of concerns about corruption and the low-standard of projects proposed by Sofia, Zoellick said. 'So what we talked about today is taking the World Bank's loans and restructuring those not to focus so much on laying asphalt on roads but to help build capacity,' he added.
