The steel flyover between Chalukya Circle and Esteem Mall in Bengaluru will, at some points, rise to the height of a seven-floor building.
BDA commissioner Rajkumar Khatri and principal manager (designs), STUP Consultants, T V Rajeev told TOI that while the minimum vertical clearance of the flyover is 5.5 metres, its height at some points is expected to go up to 21 metres. For example, at the Windsor Manor point - where there is a railway bridge - the BDA has to maintain a gap of at least 8.5 metres over the bridge."Therefore the height of the flyover is expected to go up to 21 metres from the ground.'' After Windsor Manor, the bridge will slope down to 5.5 metres. It will rise to 15 metres at Mehkri Circle, and to 19 metres at the Hebbal flyover, Rajeev said.
The magic boxes at the BDA junction, Cauvery junction, CBI and Anand Nagar will be dismantled. Khatri and PN Nayak, engineering member, BDA, made it clear that the flyover will not make only of steel.
"It's a myth. It is going to be just like any other flyover. The pillars will be made of steel, but the foundation will be of concrete. Segments will be made of steel, but the viaducts will be made of concrete topped with asphalt. Huge cranes will need many hours to mount a single 100-tonne concrete segment for the viaduct. For precast steel segments, we need just a 100tonne crane and three hours to do this. The steel piers will be set up in the shorter time," said Khatri.
