In the last twenty years the enlargement area of the European Union had both a pressure to create and a support to finance a new level of overlay infrastructure corridors. This book is a selection of the author''s comments on this process written in the past fifteen years. All the chapters are dealing with the relationship between the infrastructure network and the economic development of the area covered. The author is argueing that a better prepared and focused European support could lead to the construction of a different network pattern much more fitting to the real needs of the whole area in order to promote the European competitiveness. A missed connection pattern is harmful to the performance of the whole European Union, but especially harmful for the new member states and also for the countries accessing in the future.
