The Corporation will remodel four low-level bridges to clear bottlenecks in the improvement of macro drainage in Chennai under the JNNURM (Jawaharlal Nehru National Urban Renewal Mission).
The initiative has gained momentum after the Water Resources Department in a recent review meeting stressed the need for remodelling bridges to speed up the macro drainage improvement work. The Chinmaya Nagar Bridge and Indira Nagar Bridge will be remodelled by the civic body to suit the increase in width of the Virugambakkam-Arumbakkam drain. Stephenson Bridge and Binny Mill Bridge on the Otteri Nullah are the other two bridges likely to be remodelled on account of the widening of the macro drain.
The dimensions of the Chinmaya Nagar Bridge would increase in proportion to the new width of Virugambakkam-Arumbakkam drain. The drain would become 18-metre wide after the addition of a new box culvert by the civic body. The civic body has also issued notice to a private agency to reconstruct the Binny Mills Bridge as it is on private land.
The civic body is likely to prepare a detailed project report to facilitate reconstruction of the Stephenson Bridge.
The total funds allotted for improvement of macro drainage in the city is Rs.1447.91 crore of which Rs.814.88 crore has been allotted to Chennai Corporation. A total of Rs.633.03 crore has been allotted to the Water Resources Department. The Corporation has planned to take up 1,203 works of which 232 works have been completed at a cost of Rs.62.93 crore. Over 250 works covering 140 km of drains in the city are under way.
