The Autopista al Mar 1 project and the second Túnel de Occidente, executed by Desarrollo Vial al Mar Devimar, improves connections between the city of Medellín and the West and South West of Antioquia. It also bridges the distance between the department’s administrative capital and the ports of Urabá in Antioquia.

This road is 181 km long. The project involves building 33 km of dual carriageway, building the second Túnel de Occidente, 4.6 km long, running parallel to the existing one; repairing 76 km of road; and building 45 vehicular bridges.  This project fulfills one of our most important objectives: to improve quality of life for people through infrastructures.

We are generating a positive impact in the region 

With the Autopista al Mar 1 project, we have created more than 3,200 direct and indirect jobs. We have also implemented and executed social and environmental management programs and projects with a view to strengthening relations with communities in the region whilst improving their quality of life.  

Second tunnel tube in the Túnel de Occidente

With this project, we have connected the two sides of one of the most emblematic parts in the Autopista al Mar 1 project in Colombia. Over the course of two years, 241 people worked 24 hours a day, 7 days a week, to achieve this strategic connection between the cities of Medellin and Santa Fe in Antioquia. During the execution of the work, we faced many technical and organizational challenges.

The state of emergency generated by the Covid-19 pandemic has been an added difficulty, which our team has managed to successfully overcome. At Sacyr, we overcome challenges through our experience and energy; nothing stops us.
