At the end of 2003, Austria's trunk road financing company, Autobahnen- und Schnellstraßen-Finanzierungs-Aktiengesellschaft (Asfinag), decided to have part of its road network extended on the basis of public-private partnerships (PPP). To handle this venture, the company set up the four-package "East Region Road Program". The first package, named "Ypsilon", was announced in September 2004. In December 2006, the Bonaventura consortium was commissioned to realize the 51-kilometer section of the Vienna northeastern bypass.

HOCHTIEF PPP Solutions GmbH is leader of the consortium, in which it has a 44.4 percent stake. Together with its consortium partners, the company will finance and build the highway section and subsequently operate it for a period of 30 years. When the contract period expires, the highway will be handed over to Asfinag in perfect condition. This is the first PPP road project in Austria.
