Implemented on July 27 to combat illegal mining and stabilize local demand, Tamil Nadu's restrictions cut off over 40,000 tonnes of crushed stone and quarry dust previously shipped to Bengaluru. Contractors must now rely on alternative supply crushers in Bidadi, which has caused aggregate prices to more than double from the typical Rs 800 per tonne rate. The disruption has strained contractor finances, idled hundreds of regional transport trucks, and slowed down finishing work on the 58-kilometer airport transit project.
