A rule for the city's roads that otherwise existed only in the Brihanmumbai Municipal Corporation's (BMC) books will finally be implemented. The civic body's road engineers will now have to identify the roughness of the roads, as instructed by additional municipal commissioner (AMC) Vijay Singhal in a circular issued on Friday (mid-day has a copy).

The engineers will have to compile data of the roughness indices of all roads and get the tests done through competent consultants to ascertain whether or not repairs are required. The higher the amount of roughness, the worse the quality of the road.
