Kolkata: The Majerhat Bridge, a portion of which collapsed last week, will be demolished and a new bridge will be constructed, West Bengal Chief Minister Mamata Banerjee said on Friday.

She said there was negligence on the part of PWD officials in the bridge collapse. "They cannot avoid responsibilities," Banerjee told reporters at the state secretariat. She said the new bridge would come up in a year's time.
