THIRUVANANTHAPURAM: The construction of the flyover at Enchakkal on NH-66 bypass is likely to be delayed as the regional office of the National Highways Authority of India (NHAI) is yet to submit to its headquarters the estimate prepared as part of a detailed project report (DPR). The tender for the project can be floated only after the approval is received, said an NHAI official. With the area witnessing acute traffic congestion, a flyover at Enchakkal junction has been a long-standing demand.
