Most of the cycle path runs parallel to the Nervión river, on the south-west side of the plain. It consists of three sections, the first between its beginning and the underpass of the newly built BI-625. The second section runs from the exit of the underpass to the overpass that connects with the Martiartu industrial estate; In this section, existing roads are also used as much as possible. Finally, the third section runs on the platform of the overpass that connects the Martiartu polygon with the BI-625. Thus, an alternative itinerary to motorized ones is generated for short-medium distance routes, which is not intended to be only an alternative for sports leisure, but a real alternative for trips of any kind between the municipality and the industrial estates, promoting sustainable urban mobility , favoring access on foot or by bike from the urban center of Arrigorriaga to the area of the industrial estates and viceversa
