Please correct the details - it's not a 11 KM flyover, also what collapsed seems to be around 50 to 100 meters of the newly added 'blocks' (not confirmed from my side either) - but the following live feed shows that most of the previously added part is intact - http://sifymax.com/bbhome/sifymax_live_stream_player.php?f=http://bbmedia.sify.com/mms/new/radiolive.asp?f=hyd_punjagutta (works only on IE)
But it's really sad that 15 people died in this horrible accident. I heard the visuals on one of the TV channels show a very bad picture of the accident
