On February 26, 2021, Gabriel Martínez, the Ministry of Transport and Public Works (MTOP, for its acronym in Spanish), carried out the extension of an important section of the route between Tuntatacto and Andaluza that includes a bridge, which was completed  in stages.

With this work, overall connectivity has  improved reducing distances,  and above all, road safety has been  provided for at least 5,500 vehicles that use this arterial road on a daily basis to distribute goods, which in turn boosts tourism and the economies of the provinces between Tungurahua and Chimborazo.
