In 2003, the city of Toulouse, established and developed on a wide loop of the Garonne River, underwent a Lighting Master Plan. One of the major themes that Concepto addressed in this plan was the sublimation through light of this exceptional landscape formed by the River in the city center over 2.5 kms. In this context, the Bazacle dike or ‘Chaussée du Bazacle’ was staged, with a proposal as poetic as it was innovative.
The Bazacle dike, a shallow passage over hard rock in the Garonne riverbed, is certainly at the root of the emergence of the city of Toulouse. The present concrete construction connects the two riverbanks and zigzags between the Bazacle hydro-electrical plant and the front of the ‘Saint-Joseph de la Grave’ hospice.
This 250-meter long, emblematic broken line was highlighted using a partially dotted, luminescent pathway of blue-green color light, embedded in the causeway and exemplary of a strong ecological approach.
