The existing Unbe corridor poses a number of problems: deficient geometric characteristics (route, transverse section and visibility), high rush-hour traffic, frequent cycle traffic, problems with accesses. To address these problems, the construction design includes: improvement to the route of the BI-2704 road; definition of a section of the Urduliz Bypass; creation of a bicycle lane; planning of access roads and improvement of intersections.

The total length is 6,250 m and the design speed is 80 km/h. The type section consists of two 3.50 m lanes, with a 1.00 m median between car lane and cycle lane; cycle lanes (hard shoulders) of 1.75 m and verges of 1.5 m. There are also 5 roundabouts, a structure of 40 metres, 3 underpasses and a semi-junction with an overpass.
