To build a new tunnel under the N513, TRBA diverts the tubed Pré Granmet. This is followed by the construction of the roads with an intersection and an access road to the N58 and N513. The project ends with the splitting of the Petite Espierres concrete tubes.


The earth movement is important: 13,200 m³ of excavation and 28,700 m³ of supplemented soil. 9225 m² of concrete pavement and 12,900 m² in asphalt. The delivery of 4,500 m³ of concrete for the construction works completes the picture of impressive numbers.
