The Khammam-Devarapalli access-controlled Greenfield Highway (NH-365BG), the first such corridor connecting Telangana and Andhra Pradesh, was unofficially opened to motorists on Sunday, August 2, ahead of its formal inauguration that is expected within a week.The stretch from Tallampadu village in Khammam district to Devarapalli in Andhra Pradesh has been thrown open, allowing vehicles to use the route before its official launch. Toll collection will begin only after the formal inauguration. The opening comes after months of delay on account of the construction of railway overbridges (ROB) at Dhamsalapuram, even though the highway and most of its infrastructure had been completed nearly a year ago. With the ROBs now in place, motorists can access the highway from Tallampadu rather than being restricted to the Wayra-Devarapalli stretch through temporarily opened toll plazas. The highway has nine interchanges providing access to nearby towns and carries speed limits of 100 kmph for cars and 80 kmph for heavy vehicles. The toll system will operate on a distance-based model, similar to Hyderabad‘s Outer Ring Road (ORR). Closed circuit television (CCTV) cameras have been installed at every kilometre along the corridor and truck lay-bys have been developed at Vandanam and Chowdavaram. Of the 162.04-km total length, 105 km passes through Khammam district
