Responding to a question from AIADMK Rajya Sabha MP M Thambidurai, Union Minister for Road Transport and Highways Nitin Gadkari said short-term road safety measures have been implemented at all identified locations and that 1,298 of the 1,716 black spots require long-term interventions. He indicated long-term rectification work has been completed at 732 locations and that during the last three years long-term measures were completed at 173 black spot locations. Officials said monitoring and timely release of funds will be necessary to accelerate completion.
