The works will affect a specific section of the road, precisely between the Etxetxiki farmhouse (kilometer point 57.250) and the Sutegi cafeteria (kilometer point 57.360). Traffic will be closed in both directions during this period.

The closure will not affect the intersection between the GI-2120 road and the Lauztierreka road. Traffic needing to pass through this area will be diverted via the GI-3151 road, towards the neighborhoods of Aia and Urkillaga.

Similarly, this alternative route must also be used for travel between the neighborhoods of San Martin, San Gregorio, and Ergoiena, in both directions. Upon completion of the works, temporary signs will be removed, and normal traffic will be restored.
