LUCKNOW, March 16 -- A portion on the edge of the newly constructed Green Corridor caved in on Sunday, creating a sinkhole on the road heading towards the New Hyderabad police outpost.

"The road caved in due to breakage in the sewer line.

Kuldeep Singh, general manager, Jal Kal department, said: "One of the sewer lines developed a fault, causing a portion of the road surface to collapse," he added. Gyanendra Verma, additional secretary of the Lucknow Development Authority (LDA), said the Authority had even provided funds to shift the decades-old sewer line during the ongoing Green Corridor work. Commuters first noticed the sinkhole on Sunday morning. Soon, authorities reached the spot, barricaded the damaged portion of the road and began repair work to prevent any untoward incident.
