Our Experience

Madrid Calle 30

Madrid, Spain

The redevelopment of the Southern section of Madrid's inner ring road, known as Calle 30, included the construction of an underground bypass that required the road to be buried using a twin-tube tunnel design, with one tunnel for each traffic direction. Each tube comprises three 11.5-ft wide lanes, a 1.6-ft right shoulder, and a 2.6-ft left shoulder, designed to serve as an emergency passageway. This configuration ensured capacity, safety, and operational efficiency in one of the city's most significant urban transport infrastructures.

Lugo-Santiago Highway (A-54)

Galicia, Spain

The Lavacolla–Arzúa West section of the A-54 motorway comprises 18.5 km of newly constructed infrastructure, functionally replacing the corresponding stretch of the N-547 Lugo–Santiago de Compostela road. The alignment follows a sinuous layout, deliberately routed away from population centers and areas of high agricultural productivity, thereby enhancing road safety and reducing impacts on the surrounding environment, including the historic Camino de Santiago, which runs parallel to the former road. The project includes the construction of five interchanges of different typologies, incorporating solutions with single or dual roundabouts, ensuring efficient connectivity and traffic flow.

New Terminal Gibraltar International Airport

Gibraltar, United Kingdom

The works, commissioned by the Government of Gibraltar, involved the construction of a new passenger terminal at Gibraltar Airport, together with the expansion of the aircraft ramp, aircraft stand areas, and the associated customs and logistics facilities. The project also included a new roadway for vehicular access, provisional hangar facilities, and new cargo handling and airport vehicle installations, all carried out while maintaining the existing airport fully operational throughout the construction works.

AV de California. Fresno-Bakersfield

California, United States of America
