Grade separators on metro rail corridors

HYDERABAD: To avoid chaos at several places, especially traffic junctions, after metro rail works are completed, grade separators will be put in place at various locations on the three corridors. The Greater Hyderabad Municipal Corporation (GHMC) is likey to appoint a consultant for studying feasibility of grade separators and also identifying locations for providing them on the metro rail corridor II (JBS-Falaknuma) by April-end.

A grade separator could either be a flyover or an underpass to cross the road. Nearly, 200 grade separators might be required on the 71-km metro rail corridors__Miyapur-LB Nagar (corridor I), JBS-Falaknuma (II) and Nagole-Shilparamam for smooth flow of traffic and most of them might be required on the corridor II.

For instance, a grade separator would be required at RTC Crossroads as traffic congestion might be manifold after completion of the metro rail work. Grade separators have to be planned now by taking traffic volume at each and every intersection into consideration.

The task of identifying grade separators along with detailed project reports on the corridor I has been entrusted to the National Highways Authority of India (NHAI) as most of the stretch falls on the National Highway, while the corridor II would be taken up by the GHMC. The corridor III might be taken up either by the GHMC or the roads and buildings (R&B) department.

Official sources said top priority is being accorded for grade separators on the JBS-Falaknuma corridor as it passes through densely populated areas and the road width at most places on the stretch is just 100 feet. Also, intersections (traffic junctions) are more on the corridor compared to the other two.

GHMC officials said there were 24 intersections (junctions) on the corridor II, which covers a distance of 14.78 km, like JBS, Musheerabad, Golconda Crossroads, RTC Crossroads, Narayanguda, YMCA, Koti, Sultan Bazar, Darulshifa, Moghalpura, Shah Ali Banda, Chintalkunta, Shamsheergunj and Falakuma. The corridor would be served by 16 metro rail stations and a small depot in Falaknuma.

“The consultant will identify places and which type of grade separators (flyover, bridge or underpass) will have to be provided by taking traffic volume, availability of land and other issues into consideration. The entire exercise should be completed within four months,” GHMC superintending engineer R Sridhar said.

He said the feasibility study covers topography survey, detailed traffic study and surveys, fixing alignment, preliminary engineering designs, construction methods, benefits to road-users and cost estimation involved along with the environmental and social impact studies. “GHMC will complete the formalities of appointing a consultant by April-end,” the superintending engineer said.
