Tenders have been called for the widening of the 44-km-long stretch of Chennai – Tirupati National Highway (NH 716) from Tiruvallur to the Tamil Nadu-Andhra Pradesh border. The cost of the project to be taken up on design, build, operate and transfer or hybrid annuity basis, will be around ₹750 crore.
The present two-lane wide road will be widened to four lanes with paved shoulders on either sides on completion of the project. A total of 20 underpasses have been proposed to be constructed at major junctions.
