THIRUVANANTHAPURAM: Putting an end to uncertainties, the Kazhakoottam-Vizhinjam stretch of the NH 66 bypass is likely to have streetlights on the median soon, with two corporates evincing interest to install lights.The companies, reportedly Adani Group and Lulu Group, have come forward to install and maintain streetlights after the corporation invited Expression of Interest (EOI). However, the National Highways Authority of India (NHAI) will approach its headquarters seeking necessary permission as the companies could proceed with the plan only if light poles have their advertisement hoardings.
