The aim is to continue the development of the V81 Greenway identified as part of the regional road and green lane scheme. The operation will contribute to the development of gentle modes of travel, in particular by creating a metal bridge allowing better access to the green path for the municipalities of Mazères Lézons, Bizano and Idron. This crossing of the Gave will also allow the link between the green road and the regional tourist road Henry VI. The operation also contributes to the development of gentle modes of movement due to the development of a new section allowing the connection to the future Multmodal Pole Station of Pau.
