The public works department will carry out a study of all drains passing under the eastern and western express highway to assess the possibility of widening them. The decision comes after a joint visit by BMC chief Sitaram Kunte and PWD secretary Shyamal Mukherjee to the highways this week.
There is always a tug of war between state agencies and the BMC over cleaning of drains every year before the rains, with the PWD drawing flak at all times over not doing enough on its part.
Sources said there are four drains under the Eastern Express Highway and at least seven spots beneath the Western Express Highway that need to be widened.
"While we have undertaken works to widen and deepen drains on the upstream and downstream, the stretch beneath the highways are under PWD's jurisdiction," said a senior civic official.
PWD secretary Mukherjee said that it was impossible to cut open any part of highways, but there was a need to improve the drains' capacities. "These drains were designed when the highways were being laid. We will rope in experts and consultants to conduct a comprehensive study and come up with a solution."
