en.Wedoany.com Reported - Webuild and its joint venture partners have completed all excavation work for the 27-kilometer tunnel of Lima Metro Line 2 in Peru, a key milestone in the construction of the country's first fully underground metro system. With the breakthrough of the final diaphragm wall at Station 4, the twin-tunnel excavation is officially finished, bringing the project one step closer to operation. Two tunnel boring machines (TBMs), each with a diameter of 10 meters, operated 12 meters underground, traversing one of the most densely populated urban areas in Latin America.
Line 2 is one of Peru's most strategically significant transportation investment projects. Currently, Lima operates only one elevated metro line, and the new underground network will reshape the capital's transportation layout. The project includes a 27-kilometer section for Line 2 and an 8-kilometer section for Line 4, totaling 35 kilometers of underground railway, with 35 stations, two depots, 36 ventilation and emergency exit shafts, and two interchange stations connecting the two lines. Stations are constructed using cut-and-cover and mining methods, with the Javier Prado station being the only one built using the mining method along the entire line.
Once operational, the system is expected to transport approximately 1 million passengers daily, connecting 10 districts of Lima and reducing travel time from Ate to Callao Port from about 2 hours and 45 minutes by car to approximately 45 minutes. The line will also serve Jorge Chávez International Airport, universities, industrial zones, and Callao Port, helping to alleviate traffic congestion and improve air quality.
A previous significant milestone occurred in October 2023, when the TBM Micaela completed a 4-kilometer drive and arrived at Station E16. The machine was subsequently dismantled and reinstalled at a launch shaft on Faucett Avenue, and is currently excavating an additional 7.5-kilometer section between the Gambetta and Carmen de la Legua stations on the Line 4 branch, which will eventually connect with Line 2.
Webuild, in a consortium with European and Peruvian partners, is delivering the project under a concession contract. The overall construction is expected to take approximately five years, providing Lima with a modern, high-capacity underground railway designed to meet growing transportation demand while supporting the city's long-term environmental and economic development.
