State highways in India

In India, this is the network of roads maintained by the state governments. These roads are constructed and managed by the states' Public Works Department. The state highways are usually roads that link important cities, towns and district headquarters within the state and connect them with National Highways or state highways of neighbouring states.

As of 31 March 2016, the total length of state highways was 176,166 km. As of 31 March 2016, Maharashtra had the largest share in the total length of SH roads (22.14%), followed by Karnataka (11.11%), Gujarat (9.76%), Rajasthan (8.62%) and Tamil Nadu (6.67%).
