<p data-path-to-node="5">Removing a crucial infrastructure bottleneck for India's upcoming deep-water transshipment megaproject, the National Highways Authority of India (NHAI) has officially granted structural safety clearance for the critical utility conduits at Vizhinjam International Seaport. The engineering clearance allows for the safe completion of an underground trench framework directly underneath the active National Highway 66 (NH 66) corridor.</p><p data-path-to-node="6">The regulatory breakthrough bridges a key infrastructure gap, bringing the specialized deep-sea gateway significantly closer to launching full-scale, commercial export-import (EXIM) container logistics.</p><h3 data-path-to-node="8"><b data-path-to-node="8" data-index-in-node="0">Underground Conduit Engineering Avoids Surface Highway Disruption to Secure Port Utilities</b></h3><p data-path-to-node="9">The long-awaited clearance from the national highway authority resolves a complex coordination issue between maritime developers and road transport planners:</p><ul data-path-to-node="10"><li><p data-path-to-node="10,0,0"><b data-path-to-node="10,0,0" data-index-in-node="0">The Engineering Framework:</b> The approved project involves constructing a reinforced underground trench beneath NH 66.
