Carranza Viaduct, Urban tunnel in Palermo, Buenos Aires, Argentina.
The Carranza Viaduct is an underground tunnel in Palermo that runs beneath the Bartolomé Mitre railway line and links Santa Fe Avenue to Cabildo Avenue. The passage spans roughly 610 meters and allows vehicles to cross the rail infrastructure without surface-level intersections.
The viaduct was completed in 1995 and originally budgeted at a much lower cost, but expenses grew substantially during construction. The project arose from the need to improve traffic flow in this densely populated area by eliminating dangerous rail crossings at street level.
The tunnel stands near the Miguel Abuelo Square, which separates the platforms of the Ministro Carranza Station on the Mitre Line.
The tunnel is used daily by several bus routes and forms part of the city's public transit network. Visitors should expect congestion, particularly during peak hours when many vehicles use the narrow underground passage.
The project was viewed with skepticism by local residents for years because construction costs exceeded projections and work took longer than planned. Despite these challenges, it transformed the neighborhood and demonstrated what modern infrastructure solutions could achieve in heavily trafficked urban areas.
