Mumbai: Western Railway Replaces 129-Year-Old Bridge Between Kandivali & Borivali With Modern Structure

Mumbai: Western Railways has undertaken a significant infrastructural upgrade by re-grinding bridge number 61 between Kandivali and Borivali, replacing a 129-year-old structure with a modern pre-stressed concrete (PSC) bridge to enhance safety and durability.

The bridge, which was originally constructed in 1897 during the Victorian era, has been phased out and replaced with a high-capacity structure design to meet current operational and safety standards.

According to a press release issued by Chief Public Relations Officer, Western Railway, Vineet Abhishek, the work was carried out during a mega block scheduled from 22:30 hrs on March 28, 2026, to 19:30 hrs on March 29, 2026. Additionally, a new fast line was constructed between 01:00 hrs and 04:30 hrs on March 29, 2026. The complex engineering work was completed within a tight timeframe, ensuring accuracy while minimising long-term disruption.

The process involved removing four spans of old steel girders and installing 28 pre-stressed concrete slabs along with eight retainers after de-launching eight steel girders. PSC slabs offer greater strength, durability, and load-bearing capacity compared to conventional steel girders. They are corrosion-resistant, require less maintenance, and provide better structural stability, making them suitable for heavy suburban rail traffic and adverse weather conditions. Their use is expected to enhance overall safety while also enabling smoother and more efficient train operations.

Advanced engineering techniques and modern machinery were deployed during the upgradation work, including heavy-duty crane machines, Hyda machines, Poclain equipment, scavengers, and JCBs. Activities such as track cutting, garbage removal, lifting and installation of structures, and alignment were carried out with precision.

Over 200 personnel were involved in the execution of the project, working in coordination to complete the task within the stipulated block period.
