Sacyr Services subsidiary Sacyr Maintenance has received a contract from the General Directorate of Highways of the Ministry of Public Works for the maintenance of the ZA-04 sector in Zamora, Spain.

Worth €15.3m, the contract is valid for three years with the option for a two-year extension.

Also known as the ‘Rías Baixas Highway’, the A-52 runs from central Meseta to Vigo and provides access to the southern provinces of Galicia.

The A-52 includes the Padornelo Tunnel, which is situated at the 99km point. The tunnel is located at an altitude of 1,381m on the highway, serving as the highest-altitude high-volume road in Spain.

The highway was built in 1994 and spans over 278km.

Sacyr Maintenance performs maintenance work on road infrastructures, dams, airports, ports, irrigation canals and hydroelectric power plants.

It has maintained more than 12,000km of roads in Chile, Italy, Mexico, Peru, Spain and Uruguay.

The company has reportedly received the largest number of Spain’s research, development and innovation contracts and is headquartered in Madrid.

In March, a consortium of Ferrovial, Acciona and Lopesan won a €153m ($173m) contract for the construction of a section of highway on the Spanish island of Gran Canaria.

Under the contract, the consortium partners are responsible for building the second phase of the Aldea highway, an 8.5km-long route between El Risco and Agaete.

In June last year, Acciona Construcción chose Spanish technology company Sociedad Ibérica de Construcciones Eléctricas (SICE) to perform the integration of Caldearenas Tunnel control systems in the port of Monrepós, Huesca.
