In the transport infrastructure field, the EIB is over­seeing studies on projects such as the TGV line between Lyons and Turin, Madrid airport and major motorway routes in Eastern Europe.
Inden for infrastrukturer for transport gennemføres der undersøgelser under EIB's kontrol vedrørende projekter som f.eks. højhastighedsbanen Lyon — Torino, Madrids lufthavn og store motorvejsforbindelser i Østeuropa.
