It took all of four months for metro rail engineers to construct the Punjagutta junction flyover crossover with an eye catching arch. Providing a height clearance of little more than 18 ft, the construction was done without disturbing the traffic either on the flyover or down below on the ground in one of the busiest junction.
“It is an engineering feat considering that it spans 190 ft length and 53 ft height from ground. Apart from heavy traffic flow round the clock, there were design issues and the L&T Metro Rail engineers had to do special shuttering and staging had to be done carefully,” recalls Mr. Reddy.
Next big challenge will be crossing Khairatabad and M.J. Market junctions where works were halted to allow Ganesh idols immersion procession. While the former will be spanning 190 ft length and 23 ft high, at the market, the viaduct span will be 190 ft length and 27 ft high.

Highest flyover clearance will be at Parade Grounds - 180 ft and width 63 ft. It is here that Corridor Two – JBS to Falaknuma will be crossing with Corridor Three – Nagole to Raidurg. Metro viaduct will also be laid across Begumpet flyover and Malakpet railway station.
Cross over works over rail lines at Secunderabad railway station are under progress, expected to take a year. “We have Railway Board approvals but at each and every stage design approvals have to be taken from railway engineers,” says Mr. Reddy.
