A railway tunnel, longest in South India, is being constructed through Veligonda hills as part of the Krishnapatnam-Obulavaripalli railway project.
The Rail Vikas Nigam Limited (RVNL) is using modern technology to build the tunnel with 7.56 km. The authorities expect the construction would be over by the end of this year.
The Indian Railways has planned to take up the rail line in the tunnel adopting the non-ballast track system for hassle-free maintenance and also for managing maximum speed in the tunnels allocating Rs 839 crore especially for the tunnel.
The tunnel will be going through Veligonda hills. The hills had remained the main hurdle for the movement of men or material between Kadapa and Nellore districts. The Veligonda hill range separates Kadapa district from Nellore.
Starting from Nagari in Chittoor district, the tunnel runs in a northerly direction along the western border of Nellore district, rising to an elevation of 3,626 ft at Penchalakona in Rapur mandal. Read More
