In its second phase of the footpath improvement scheme, the Chennai Corporation has decided to redesign and develop footpaths in 249 bus routes in the city. A sub-committee of the Chennai Unified Metropolitan Transport Authority (CUMTA) on November 5 took a decision to invite bids to redesign these stretches.    As part of the scheme, Chennai Corporation will remove encroachments on the footpaths.  Work on footpaths in the first phase has been restricted to 71 bus route roads in eight zones of Tondiarpet, Royapuram, Thiru-Vi-Ka Nagar, Anna Nagar, Teynampet, Kodambakkam, Alandur and Adyar.    In the first phase, most of the new granite footpaths are going to be built at two-metre wide. The major roads being covered in the first phase include Ethiraj Salai, Pantheon Road, Police Commissioner Office Road, Gandhi Irwin Road, Valluvar Kottam High Road, Sterling Road, Sterling Avenue, Tank Bund Road and Mahalingapuram Main Road.
