NVS Reddy, the managing director of Hyderabad Airport Metro Ltd (HAML), and senior engineers examined the Airport Metro alignment on the Rajendranagar hills on Wednesday. The construction of the Airport metro viaduct on this hillock will be a tough task because of the tremendously undulating terrain full of steep heights, rocks, and valley spots, according to HAML.

Following an inspection, the HAML has decided to install protective barriers on the ORR side that are strong enough and tall enough to prevent boulders from rolling onto metro rail. These protection barriers were suggested since the ORR's design leaves barely 18 feet between the Metro alignment and the crash barrier edge.

In order to allow rainwater to enter the ORR drainage system, cross drains with pipes of sufficient diameter will be installed at the temporary road that HAML built on the hill.

In order to facilitate the pre-construction activities, the final 300 metres of the temporary road on the hillock will be laid in the upcoming days.
