Widened Nag River Flows Close to Metro Pillars Near Krazy Castle; Safety Measures in Place

Nagpur: The ambitious Nag River widening project, aimed at mitigating flood risks in the city, has reached a technically complex stretch near the former Krazy Castle amusement park — where the riverbed now runs extremely close to Metro Pillars 176 and 177.
While the river is currently dry due to ongoing construction, the situation is drawing attention with the onset of early monsoon, which will soon bring water into the newly widened channel.
The project, executed by MahaMetro, involves widening the riverbed to 18 metres to restore its flow capacity and avoid bottlenecks like the one that contributed to the city's flood on September 23, 2023. However, achieving this width near the Metro alignment posed a unique challenge, as the channel edges came within metres of live infrastructure.
When TOI visited the site, it was found that on one side of the viaduct, where the retaining wall is yet to be built, the widened riverbed was literally brushing against the pillar base, with one face of the pillar exposed to the open. Though there is no water flow currently, the close proximity has raised questions about preparedness before the rains arrive.
Responding to concerns, Rajeev Tyagi, director (projects), MahaMetro, said that extensive precautions were taken to safeguard both, the Metro structure and public traffic.

"To achieve the required width near the piers without disrupting live roadways or compromising safety, a series of pile foundations was cast near the existing Metro pier," he said.
A total of 30 piles — each 600mm in diameter and 8.5m deep — were installed in just two days. "Piling was done while maintaining a safe distance from the Metro's overhead electrical (OHE) lines. Near the structures, piling was executed at night after commercial Metro operations ended, and the OHE was discharged to ensure absolute safety," Tyagi added.
After piling, MahaMetro began work on a 30-metre-long jacketing wall, designed with curvature around the piers to allow smooth water flow. The height of the wall is aligned with High Flood Level (HFL) data provided by civic bodies.
Officials say the widened section will help increase discharge capacity to 140 cumecs as recommended, reducing flood risk downstream. They emphasised that safety measures were planned and implemented to ensure that both Metro infrastructure and future river flows are secured.
