July 5, 2025: The Mumbai Trans Harbour Link (MTHL), also known as the Atal Setu, has recently come under scrutiny following public reports highlighting the absence of a crucial vision barrier panel and early signs of road surface wear. In response, the Mumbai Metropolitan Region Development Authority (MMRDA) swiftly initiated repair works, reflecting the urgent need for ongoing supervision and maintenance of such large-scale infrastructure.
Inaugurated on January 12, 2024, the Rs 17,843-crore Atal Setu is India’s longest sea bridge and a key connector between Mumbai, Navi Mumbai, Panvel, JNPT, and the upcoming Navi Mumbai International Airport. While it has significantly enhanced regional mobility and economic integration, recent issues raise serious questions about long-term upkeep and monitoring.
One of the bridge’s standout features is a six-kilometre stretch equipped with noise and vision barriers. These installations serve two primary purposes: shielding the Bhabha Atomic Research Centre (BARC) from view for national security reasons and safeguarding the ecologically sensitive Sewri mudflats, home to migratory birds like flamingos. The missing panel not only poses a threat to environmental protections but also represents a potential security lapse.
Adding to the concerns is the emerging trend of motorists stopping illegally on the high-speed bridge to take photographs. This behaviour endangers both commuters and the structural integrity of the access-controlled expressway.
While MMRDA contractors have responded quickly by initiating repairs, including fixing the vision barrier and addressing road surface flaws, the incident highlights the necessity for stringent, proactive maintenance and public discipline.
The Atal Setu is more than a transit project—it’s a symbol of smart urban infrastructure. Its long-term success will depend not just on reduced travel times but on upholding standards of safety, environmental stewardship, and civic responsibility.
