TRANS-GARONA aims to develop cycling journeys (daily, leisure) by improving cross-border cycling and intermodality along the Garonne. This objective will be achieved through three flagship actions: - build a Garonne cycling path along the river from the heart of Toulouse to its sources in Spain. Sections of this bike path have already been developed by the Cd31 and the CG Aran. By realizing the missing link of 21 km between Fronsac and Vielha, TRANS-GARONA will make it possible to complete this journey by 2021 and to give it an European value, - promote intermodality by better coordinating the Franco-Spanish correspondences of buses, trains and bicycles, and thus propose real alternatives to the car in daily trips, also to discover the patrimonial and natural wealth of the territories, - create a "Garonne in bike" product under a common label proposing visitors and residents complementary offers ranging from "Bicycle leisure" to "sport bike". TRANS-GARONA is finally the first stone of a wider ambition, that of finally connecting this Garonne course: - to the Canal des 2 Mers V80 and thus connect the estuary to the sources of the Garonne, - to the EV6, EV3, EV16, and thus offer a new euro-bike in the heart of the Pyrenees, - to the TransCatalunya bike routes, the EV8 and V81 to reflect in the future about a cross-border cycle plan Pyrenees.
