At the end of last year, ACA E&C signed a contract with ABC (Administración Boliviana de Carretera) to rehabilitate the La Angostura road.

The project for the Rehabilitation of the Comarapa - Mataral road consists of works that will improve the
service conditions of the road, with the enlargement of the platform to 9 m, 8 m of bituminous pavement plus 0.5 m of berms, the execution of longitudinal and transversal drainage, the rehabilitation of 5 bridges, and the intervention in some critical points of sliding of the hillside with the construction of support walls. The rehabilitation of the existing pavement will be done by recycling the pavement with cement.
