To ease traffic snarls in Bangalore, flyovers and ring roads have been built and are being built in several areas. But prolonged delays in building some flyovers like the ones at Thanisandra, BEL Circle in the city have been causing hardships.    Vehicles move inch by inch on these roads when the flyovers are still being constructed. The Outer Ring Road, designed to give Bangaloreans a free ride along the suburbs, is five years old and nowhere near completion.    The massive project - a series of 10 connected flyovers, three underpasses and two railway bridges on a total stretch of 13.4km -- has only created a multitude of problems to commuters. In the past five years, the only reality has been traffic bottlenecks, broken roads and dust pollution. The Rs 292-crore project, implemented by the BDA, is meant to connect HSR Layout 14th Main, Agara, Iblur, Bellandur, Devarabeesanahalli, Kadubeesanahalli, Mahadevapura, Kalyan Nagar, Hennur, Veerannapalya and BEL Circle.    Work started in mid-2009 and each flyover was to be done in 24 months. But most flyovers took three years. The ones at Thanisandra and BEL Circle junctions are still unfinished. At Thanisandra, two high-tension lines parallel to the flyover and shifting of utilities is delaying the project. At BEL Circle, the road is half-dug. A PSU has refused to part with land to widen the road, say sources.
