THIRUVANANTHAPURAM: Despite promises by the city corporation to install street lights along NH-66 bypass before the local body elections, nothing has happened so far. In January last year, former Mayor K Sreekumar had given the assurance to install streetlights in the first reach of NH bypass stretching from Kazhakootam to Mukkola, near Vizhinjam. The pleas of the Technopark employees to provide proper lighting also fell on deaf ears.
