The Trichy-Thanjavur NH is a critical artery that supports significant vehicular movement, connecting key urban and rural regions. Given the high traffic volume, the NHAI's focus on service roads is intended to facilitate smoother local traffic flow, reducing congestion and enhancing access for local commuters. Service roads are essential for providing direct access to properties adjacent to the highway without disrupting the main traffic flow.

The prioritization of service roads over a flyover is also seen as a strategic move to address immediate traffic concerns while planning for future infrastructure enhancements. This approach ensures that the current infrastructure can handle traffic demands efficiently and safely while larger, more complex projects like flyovers are developed.

By focusing on service roads, NHAI aims to offer immediate relief to the congested areas along the Trichy-Thanjavur NH. These service roads are expected to play a crucial role in separating local traffic from highway traffic, reducing the risk of accidents, and enhancing overall road safety.

NHAI's decision reflects its commitment to a balanced and pragmatic approach to infrastructure development. While flyovers offer long-term solutions to traffic congestion, service roads provide immediate and effective relief. This strategy not only addresses current traffic issues but also lays the groundwork for future improvements, ensuring sustainable and safe transportation infrastructure.
