The Kochi Bypass is a segment of National Highway 66 that bypasses the CBD of the city of Kochi in Kerala, India. The highway stretches 17 km from Edapally in the Ernakulam district to Aroor in Alappuzha district, via Palarivattom, Vyttila, Kundannoor, Madavana and Kumbalam. The Government of Kerala began the preliminary works in 1973. After a slow progress, it was partially opened for traffic in the beginning years of the 1980s. The section between Edapally and Vyttila had four lanes from the beginning. The rest of the carriageway was also upgraded to different sections of 4 lane, 5 lane and 6 lanes by 2010.

National Highway 66, commonly referred to as NH 66, is a mostly 4 lane 1640 km long busy National Highway that runs roughly north–south along the western coast of India, parallel to the Western Ghats. It connects Panvel, a city east of Mumbai to Cape Comorin (Kanyakumari), passing through the states of Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu.
