The bridge is also considerably damaged by pedestrians spitting out acidic, lime-mixed stimulants (gutka and paan). A technical inspection by Port Trust officials in 2011 revealed that spitting had reduced the thickness of the steel hoods protecting the pillars from six to less than three millimeters since 2007. The hangers need those hoods at the base to prevent water seeping into the junction of the cross-girders and hangers, and damage to the hoods can jeopardize the safety of the bridge. KoPT announced that it will spend on covering the base of the steel pillars with fibreglass casing to prevent spit from corroding them.
