Expressways are the highest class of roads in India. In July 2023, the total length of expressways in India was 5,579 km (3,467 mi), with 8,366 km (5,198 mi) under construction. These are controlled-access highways where entrance and exits are controlled by the use of cloverleaf or trumpet or grade separated interchanges that are incorporated into the design of the expressway and designed for maximum speed of 120 km/h, whereas National highways are flyover access or tolled, where entrance and exit is through the side of the flyover, at each intersection of highway with road, flyovers are provided to bypass the city/town/village traffic and these highways are designed for speed of 100 km/h. Some roads are not access-controlled expressways but are still named expressways, such as the Biju Expressway, these are actually state highways that are not declared by the central government as an Expressway, hence not an Expressway or National Highway.
