Last month, a manhole at Jain Nagar in Chromepet caved in and a part of the road sunk for 20 ft.
This has put several commuters and pedestrians in distress as other parts of the same road are filled with large craters now.
Chennai-Tambaram bypass near Perungalathur bus stand, Mudichur Manivakkam Road, Nemilicherry Road, Thirumudivakkam-Thiruneermalai Road, 200-ft Radial Road towards Selaiyur are other roads that require immediate attention.
Jain Nagar, AGS Colony, Kurunji Nagar and Radha Nagar have unmotorable roads,” said V Santhanam, a social activist from Chromepet.
Similarly, due to the ongoing flyover construction along Pallikaranai-Medavakkam Road, near one junction, the road is badly damaged said residents.
