MUMBAI: The Mithi could pose a serious threat to life and property in case of heavy rain.

Although the former chief minister Vilasrao Deshmukh had approved the widening of the Mithi at CST bridge near Kurla up to 100 m in the aftermath of the July 26, 2005 deluge, a directive by the state's empowerment committee led by chief secretary Johny Joseph, reduced the width to just 60 m.
