The New Indian Express. CHENNAI: Motorists spent nearly 30 to 40 minutes covering the five-km stretch between Tambaram and Kilambakkam on GST Road on Friday, as the highway witnessed massive vehicle pile-ups. Affected landowners and farmer representatives have demanded clear written assurances on market valuation and fair compensation norms before field surveys or land acquisition proceed. District officials are expected to hold consultations with local stakeholders to resolve the impasse.
