Bhandup West residents staying close to LBS Marg are scared that their buildings may go Ghatkopar's Siddhi Sai or Bhendi Bazar's Husaini Manzil way. Reason? Illegal construction, of course. They have alleged that shop owners whose structures were demolished as part of BMC's road-widening work have rebuilt dangerous and rickety buildings in the allotted space, which could endanger the residential dwellings right behind these.
