Infrastructure priorities and investment needs for the Trans-European Transport Network (TEN-T) until 2030   

Nine studies, published by the European Commission, show that approximately €700 billion of financial investment is required for the development of the TEN-T core network.

These studies, the first comprehensive analysis of tens of thousands kilometers of rail, road, inland waterway connections, ports, airports and other transport terminals, define a preliminary lists of projects that could feed into the reserve of projects under the Connecting Europe facility and the Commission's €315 billion Investment Plan.

The Commission plans to launch new studies around mid-2015 which building on the present studies will consolidate project lists or the approach to prioritising projects.
