Improvements to the Puerto Nuevo - Quillaico route will connect the cities of La Unión and Lago Ranco by repairing the road, implementing new solutions and finishing the paving of the entire ring road of Lago Ranco. Completion of the bridge construction over the Bueno River in Puerto Lapi is the most recent milestone achieved. The bridge is 170 m long and comprises 4 spans, measuring 42.50 m each, with a deck width of 13.96 m. There is no doubt that this project will bring social, touristic and economic improvements to the province and region.
