Bangalore to pioneer steel flyovers

Bangalore to pioneer steel flyovers
The Economic Times


DESPITE the infrastructural hiccups it experienced during the recent deluge of rains, Bangalore continues to have many firsts to its credit. This round, it will usher in a successful German technology of laying steel flyovers in the city. Two pilots will be executed in the city next year, whose success may then spawn more such structures across India’s silicon capital, and herald an end to the future construction of traditional concrete flyovers. The bids for the project are being called for this month.

The flyover structure can be fabricated in four months by the manufacturer and erected on the road within a fortnight, Bangalore Development Authority (BDA) Commissioner M N Vidyashankar told ET.

While these flyovers cost nearly thrice the price of a conventional structure, they can be installed faster and with minimum discomfort to the public. While a typical flyover can be built in nine to 12 months, some projects have taken considerably longer for implementation.

Apart from a shorter timespan, these steel flyovers promise much slower wear and tear compared to the conventional concrete structures. They can also be shifted to another location depending on the traffic flow on a stretch.
This flexibility is significant because the changing volume of traffic often makes a flyover insufficient to ease the flow and alternative solutions need to be generated.
