CHENNAI / NEW DELHI, October 7 — The Ministry of Road Transport and Highways (MoRTH) in coordination with the National Highways Authority of India (NHAI) on Wednesday sanctioned a revised financial and structural outlay of ₹5,855 crore for the 20.6-kilometre, 6-lane Chennai Port to Maduravoyal elevated double-decker corridor.
Under the engineering blueprint, the corridor ranks among India's most complex urban double-tier elevated roadways, engineered primarily along the banks of the Cooum River. The lower deck provides designated grade-separated lanes for intra-city commuter traffic between Koyambedu and Chennai Beach, while the exclusive upper tier connects heavy freight container trailers directly from National Highway 48 (Chennai–Bengaluru highway) into the core container berths of Chennai Port without entering metropolitan surface arteries.
Logistics economists noted that dedicated grade separation will compress cargo transit delays between suburban manufacturing belts in Sriperumbudur–Oragadam and the port from an erratic 8 hours to under 45 minutes, dramatically lowering round-trip freight detention costs. The project forms an integral multimodal link under the PM GatiShakti National Master Plan, directly augmenting Southern India's maritime export competitiveness across automotive and electronics hardware.
Port connectivity corridors, the Sagarmala Programme, multimodal logistics parks (MMLP), and urban freight decoupling physics represent essential subjects across UPSC Civil Services (GS-III: Infrastructure) and civil engineering competitive tests. Aspirants should note that Chennai Port, inaugurated in 1881, stands as the second largest container port on India's eastern seaboard, and the Sagarmala initiative was institutionalized in 2015 to modernize port infrastructure, enhance hinterland connectivity, and promote port-led industrialization.
