The shares of the engineering and construction major Gammon India, which plunged 16.11 per cent in the morning trade, closed with an over six per cent decline on the Bombay Stock Exchange, as investors dumped its shares after one of the bridges it was constructing in Kota, Rajasthan collapsed last Thursday.

The scrip tumbled 6.05 per cent to close at Rs 225.10 today. During the intra-day trade the scrip had plunged 16.11 per cent to a low of Rs 201 on the BSE.
