Lakshmikant Reddy, acting as authority, has mandated the total redirection of vehicular traffic from the deteriorating old bridge to the adjacent newly constructed bridge on National Highway 766. This shift, currently impacting the Mysuru-Nanjangud corridor, serves as a stopgap to facilitate long-delayed structural rehabilitation.
Core Operational Shift: All bidirectional traffic is now consolidated onto the new span to allow for the urgent repair of the compromised older masonry infrastructure.
Transit Logistics & Infrastructure Stress
The decision follows pressure from the National Highways Authority of India (NHAI), which cited the decrepit state of the old bridge as a primary concern. The transition has created friction between safety priorities and flow efficiency:
Flow Control: While the Superintendent of Mysuru District Police confirmed the feasibility of the conversion, internal concerns persist regarding the new bridge’s capacity.
Congestion Risks: The shift risks bottlenecks on the single span, potentially hindering the arterial movement of vehicles between these urban nodes.
Urgency: Officials emphasize that repairs must proceed immediately to mitigate the risks of structural failure on the original site.

Historical and Environmental Context
The original Kabini structure is defined by its Gothic-style stone arch architecture, featuring 56 piers and spanning 225 meters. Built for a different era of logistics, its longevity is attributed to traditional lime mortar and dressed stone, yet it remains vulnerable to the river's dynamic nature.

Flood Susceptibility: The site sits near Nanjangud, a town frequently beset by riverine flooding. Records show that high discharge rates from the Kabini Dam—at times exceeding 70,000 cusecs—regularly inundate the surrounding NH-766 geography, placing repeated stress on both modern and legacy infrastructure.
Development Dissonance: While railway divisions have historically pushed for the preservation and "facelift" of the older masonry as a Heritage Structure, the modern transport demand of the NHAI creates an asymmetric requirement for high-load industrial use.
The bridge represents a collision between early, landscape-responsive civil engineering and the Infrastructure Requirements of an expanding road network. The tension remains: how to maintain a monument that was never engineered for the Logistics Load of current century traffic.
