LARGE INFRASTRUCTURE PROJECTS
The Required Size of Projects for a More Competitive Europe.
Large Infrastructure Projects initiated the ABC+De project which was developed as the missing TEN-T Corridor in Eastern Europe between the Aegean Sea and the Baltic Sea, from South to North. It also includes the river Danube from Germany well down to its delta.
The Danube – Aegean Sea Motorway is just another sub-project within the extensive ABC+De project. Fast and effective, ABC+De is a true Pan – European initiative. It is entirely based on economic profitability models and thrives for growth of the real European economies.
ABC+De stands for Aegean to Baltic Sea Connection & Danube. Economic viability comes first.
Since 2012, we have tirelessly been working on the project, which combines two main transportation corridors of great value: a new transportation artery in Eastern Europe & converting the River Danube into a real corridor.
New Aegean - Baltic TEN-T Corridor
This is the missing and yet necessary TEN-T Corridor that will ensure economic growth for some of the most underdeveloped regions of the EU.
Ports
South – North Stream Railway Line (SNS)
Multimodal Logistics Centers
Using the benefits of and combining the diverse modes of transport for both passengers and delivery of freights from door to door through new high – tech logistics centers.
Motorways
This is a network of motorways that will allow to travel freely by car from the Baltic region to the Aegean Sea.
Danube River
Management of the Danube River and its tributaries reducing the negative impact of climate change and turning the waterway into an efficient transportation Corridor.

Social Entrepreneurship
The ABC+De is a visionary project for Europe aiming at societal prosperity. We are a socially aware private organization whose mission is to creatively provide solutions to transportation and urban problems from a bottom up perspective – the end user, commuter, logistics company, private enterprise. Solving long persisting ecological problems and creating a sustainability model for a number of generations, we believe that the private initiative in all activities of life have to nearly always precede the governmental and supra-governmental ones.
Innovations in the ABC+De Project
Innovations is a major driving force at Large Infrastructure Projects
By solving transportation and freight issues through Innovations, our strategy also emphasises on the ecological, social and cultural impact of our projects.
The Innovations used in the ABC+De project will contribute to the EU principle for freedom of movement and higher mobility.
These innovations are technical, engineering, organisational, and others. You can contact us to learn more.
