Colombia's National Infrastructure Agency (ANI) and Estructura Plural SAC 4G have signed the Sea highway 1 'Autopista al Mar 1′ PPP project.

Estructura Plural SAC 4G is a consortium composed of Sacyr Colombia S.A.S. (37.5%), Strabag S.A.S.(37.5%) and Concay S.A. (25%).

The 176 km road will connect the city of Medellín and the Sea highway 2 "Autopista al Mar 2". The project involves the construction of 17 tunnels and 41 bridges. It includes the following road stretches: Occidente-San Jerónimo, San Jerónimo-Santafé de Antioquia, and Bolombolo-Santafé de Antioquia.

The total project investment is estimated at P1.51 billion (US$478.8 million).

The project, which belongs to the 'Autopistas para la Prosperidad' package of highway projects, is part of the second wave of 4G highway projects, including a total of 9 concessions. This second wave includes a total investment of about P11,800 billion (US$4.64 billion). 4G involves the construction of about 8,000km of roads, including 1,200km of four-lane highways, with the majority of projects to be carried out as PPPs.

In mid August we reported on the commercial closure of the Santa Ana - Mocoa - Neiva highway PPP project. During the same period a total of  three road PPP projects achieved financial close in the country: Girardot-Puerto Salgar, Cartagena - Barranquilla and Pacific Connection highway concession 3. Three teams submitted final bids for the Sea highway 2  "Autopista al Mar 2", which will improve the connection of the city of Urban Medellin and the Pacific Coast.
