This project comprised 864 meters in length of the Circunvalación Highway, which included a 550 meter-long underpass, 6 lanes, 3 in each direction, allowing uninterrupted transit from north to south of the capital, and vice versa. This road connects the Costa Rican capital with nearby urban conglomerates in Curridabat, Desamparados, Zapote and San Pedro, through which 56,000 vehicles pass daily. The project substantially improved traffic and reduced travel times.

• Drilling, assembly and casting of 786 piles with an average depth of 13 meters
• Excavation of approximately 80,000.00 m³.
• Laying 4,500 meters of drainpipe.
