HMR to begin rail crossover work

The metro line viaduct will be built across the existing six railway lines and also another couple of lines proposed for future expansion

Work on the first land railway line crossover by the elevated metro project will begin at Bharatnagar on the second stage of construction schedule between Miyapur-S.R.Nagar, which forms part of Corridor One - Miyapur-L.B.Nagar - in the next few days.

Senior officials and engineers of the Hyderabad Metro Rail (HMR) and the concessionaire L&T Metro Rail Hyderabad (L&TMRH) have been going through the minute details of the landscape and the construction elements required for the technical feat of the crossing over on the right side of the Sanathnagar flyover (from Erragadda).

Work will be done in such a manner that the metro line viaduct will be built across the existing six railway lines and also another couple of lines proposed for future expansion without any piers in between, said HMR Managing Director N.V.S. Reddy. One of three spans planned at the site will be 213 ft long (65 metres) to cross over all the existing and proposed railway lines on the ground. The lengthiest span crossing over the railway lines will be at Oliphant Bridge - 272 ft (83 metres) followed by the one to be built at Bhoiguda - 220 ft (67 metres). Other 213 ft viaduct spans will be constructed at Begumpet and Chilkalguda.

At Bharatnagar, the other two spans will be of 128 ft long each (39 metres). The angled pier to shift the viaduct direction will be built about 500 metres from the start of the flyover on both sides, said M. Vishnu Vardhan Reddy, General Manager, HMR. It also means the metro line will be moving at a slightly higher level in parallel to the flyover.

Eight crossings

The next stage of the railway crossover will be at Alugaddabavi, Mettuguda.

The metro rail will be crossing over the traditional railway lines at eight crossings including old Gandhi Hospital, Lakdikapul and Malakpet.

It will also be crossing over flyovers at Greenlands, Hi-Tec City, Punjagutta, Nalgonda crossroads and Narayanguda crossroads while it will be built alongside the flyovers of Tarnaka, Hari Hara Kala Bhavan, CTO, Airport, Begumpet and Khairatabad.

At three metro rail stations, one corridor will be built over the other like at Ameerpet corridor one will be over corridor three, MGBS corridor two will be over corridor one and Parade Grounds corridor two will be over corridor three, added HMR MD.
