Major metropolitan transit and infrastructure projects continue to advance across several regions, marked by construction milestones and service adjustments. In Bogotá, Metro Line 1 construction has reached an 82.33% execution rate, with 18 kilometers of the planned 24-kilometer viaduct completed and over 9 kilometers of double railway track built. The 19th train has arrived at the Bosa workshop, and testing has commenced on the viaduct in both directions; commercial operation is anticipated to begin in March 2028. To facilitate construction, TransMilenio S.A. will implement a total closure of the Calle 22 temporary station on Avenida Caracas from October 11 to October 31, followed by recurring weekend and nighttime closures. In Madrid, Metro de Madrid is conducting safety tests for Line 6 automation, requiring 48-hour service interruptions between Cuatro Caminos and Lucero on the weekends of September 26-27 and October 3-4, with free replacement buses provided. Long-term plans include a Y-shaped branch for Line 1 by 2030 and a new diagonal route for Line 11. Other regional developments include tunnel excavation for Seville’s Line 3 North Metro using the ‘tunnel in mine’ method under the Hospital Virgen Macarena parking lot, and the installation of a 10-degree inclined tower for Guatemala’s AeroMetro project. In Caracas, the National Institute of Land Transport scheduled road closures for late September to accommodate road marking and signaling works. Additionally, studies in Quito indicate that extending the metro north toward La Ofelia may require approximately eight additional compatible trains to maintain service frequency. Recent progress includes the commencement of an environmental assessment by the Metropolitan Transportation Authority (MTA) to extend New York’s Q subway line through the 125th Street corridor in Harlem.
