Kerala Chief Minister V.D. Satheesan writes to his Tamil Nadu counterpart, C. Joseph Vijay (referred to in one report as C. Joseph Vijay), urging the Tamil Nadu government to ease restrictions affecting the transport of stone aggregates. Satheesan says Kerala has limited natural availability of suitable stone aggregates for large-scale infrastructure works, including ongoing National Highway (NH) projects. He adds that Kerala has depended on neighbouring districts in Tamil Nadu to meet aggregate requirements for these works. The request is focused on relaxing the transport restrictions so materials can continue moving to support NH-related construction and maintenance in Kerala. The letters outline the constraints faced in securing adequate supplies within Kerala and frame the issue as a practical supply-chain challenge for infrastructure delivery. Both reports present the initiative as a direct inter-state appeal by Kerala to ensure continuity of NH work that relies on aggregate sourcing from Tamil Nadu.
