National Highways Authority Of India [NHAI] — Poor drainage maintenance along nh16 in Martur, Prakasam district, Andhra Pradesh

Alongside NH16, the highway authorities constructed a drainage of poor quality and it is not at all serving the purpose even for small rains. Drainage water is being pushed into house since the main drainage constructed by highway authorities is not in good shape and is blocking the rain water flow. We are not sure on whom to contact. Local residents near my area are claiming that they reported this issue several times and they have never got any response or solution. It would be really helpful if someone take a look at this issue and make sure that flood water flow smoothly through the main drainage.
