Largest RCC Box Structure Pushed Beneath Live Railway Track

The record for the largest RCC box structure pushed beneath a live railway track was set by Montecarlo Limited, India. Beginning on June 26, 2025, a railway under-bridge was built at location 287 (railway KM 150/200–200C, NH948A KM 154+503), between Kelamangalam (Tamil Nadu) and Hosur (Tamil Nadu) stations, as part of the 8-laning of the bypass. Six RCC boxes (8m (L) × 17m (W) × 6.85m (H) segments were pushed 24 meters and installed using the air-pushing technique. The project was completed on September 2, 2025, as confirmed on October 29, 2025.
