Heavy rainfall in Tamil Nadu has led to significant disruptions on the Chennai-Trichy highway (NH 32), with large portions submerged under floodwaters. Key stretches near Iruvelpattu and Arasur were completely washed away, rendering the road impassable for motorists. This resulted in a traffic jam stretching over 8 km on the Villupuram Bypass Road on Monday night, as vehicles were rerouted to alternate paths. However, these detours were not immune to the impact of rising floodwaters, forcing authorities to close two diversions, further exacerbating the delays.
For vehicles travelling to Chennai from southern districts such as Madurai and Trichy, the detour added a substantial 50 km to the usual journey. Commuters were rerouted from Asanur to Thirukovilur, followed by a long detour via Tiruvannamalai and Gingee to rejoin NH 32. Despite these efforts, traffic barely moved, with some travellers spending up to three hours to reach their destination. Similar disruptions affected the East Coast Road, complicating an already challenging situation for commuters.
Rail services were equally impacted, with 48 trains delayed due to flooding in the Villupuram section. Many trains heading south were forced to divert, while Chennai-bound trains faced delays of six to eight hours. Passengers stranded between stations endured harrowing conditions, with some lacking food or water for extended periods. In response, the Southern Railway deployed special buses to assist those stranded at Villupuram railway station, providing food and water to alleviate the distress.
The flooding crisis highlights the vulnerability of key transportation networks and the need for long-term planning and resilience. From a civic perspective, urban infrastructure in flood-prone areas must be better designed to cope with extreme weather events, reducing the impact on commuters and residents. Moreover, sustainability efforts need to focus on creating flood-resistant infrastructure, ensuring that transport networks remain functional during severe weather events. It’s a reminder of the increasing need for climate-resilient urban planning.
