As the monsoon arrives earlier than anticipated this year, authorities responsible for the Mangaluru–Bengaluru National Highway 75 (NH-75) have accelerated efforts to ensure seamless traffic movement on one of the region’s most critical transport corridors.
Following instructions from senior officials to mitigate disruption caused by ongoing construction on the BC Road–Addahole four-lane stretch, several key infrastructure projects including flyovers and vehicle underpasses have been opened to the public. The NH-75, a vital artery linking Karnataka’s commercial hubs, has faced considerable congestion and public inconvenience due to expansion works, particularly near the Kalladka flyover. In response, highway management authorities adopted a proactive approach by prioritising the swift completion and operationalisation of alternative traffic routes to prevent bottlenecks during the peak monsoon period.
Among the newly commissioned infrastructure are two vehicle underpasses near Mani and Uppinangady, which became accessible to traffic from May 29. Additionally, the left section of the Kalladka town flyover is set to open from June 2, promising further relief to motorists navigating this busy stretch. These developments reflect a strategic emphasis on maintaining smooth vehicular flow while construction proceeds. In tackling one of the persistent challenges during heavy rainfall — waterlogging — officials have overseen the installation of a pipe culvert at Thumbay. This targeted intervention aims to eliminate water stagnation, which has historically caused severe traffic snarls and safety hazards on the highway during monsoons.
Highway planners and experts have underscored the importance of integrating climate-resilient design principles into infrastructure projects like NH-75. By incorporating effective drainage systems and flood mitigation measures, the highway expansion aligns with broader goals of building sustainable, eco-friendly transport networks that can withstand increasingly erratic weather patterns linked to climate change. The progress on NH-75’s expansion is noteworthy. As of late May, 14.4 kilometres of the 15.13-kilometre Addahole–Periyashanthi section is complete. Furthermore, 41.52 kilometres out of 48.485 kilometres between Periyashanthi and Bantwal have been finished, significantly reducing traffic congestion in these regions and improving overall connectivity.
These enhancements not only facilitate more efficient movement of people and goods but also contribute to lowering carbon emissions by reducing idle time in traffic jams. Smooth traffic flow decreases fuel consumption and air pollution, a crucial step towards creating more sustainable and equitable urban environments. Authorities have made it clear that these infrastructure improvements are part of a larger vision to modernise the national highway network while prioritising the safety and convenience of commuters. The ongoing construction sites across the district are being closely monitored to swiftly address any emerging challenges, particularly those posed by the monsoon rains.
Moreover, a detailed survey of flood-prone zones along the highway has been commissioned, ensuring that future projects will incorporate anticipatory mitigation strategies. This approach highlights a commitment to resilient infrastructure development that anticipates climate risks rather than merely reacting to them. Traffic management experts also advocate for continued public communication and real-time updates to drivers, enhancing awareness and preparedness during construction phases. This people-centric approach to infrastructure development acknowledges the human experience at the core of urban planning and transport policy.
While the expansion of NH-75 is primarily aimed at easing transport logistics, it also carries significant economic implications. Improved highway infrastructure supports regional trade, tourism, and industrial activities, thereby contributing to the socio-economic upliftment of surrounding communities. This case exemplifies how infrastructural progress can be achieved in tandem with sustainable development principles, balancing the urgency of urban mobility needs with ecological responsibility and social equity.
As the monsoon intensifies over the coming weeks, the authorities’ focus remains steadfast on ensuring uninterrupted traffic flow, maximising commuter safety, and enhancing the resilience of critical transport corridors like NH-75. The experience gained here may well serve as a blueprint for future infrastructure projects across the country, fostering greener, safer, and more efficient highways that respond dynamically to environmental and societal demands.
