An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.

Expressways are the highest class of roads in India. In July 2023, the total length of expressways in India was 5,930 km (3,680 mi), with 11,127.69 km (6,914.43 mi) under construction. These are controlled-access highways where entrance and exits are controlled by the use of cloverleaf, three-way, 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 Bagodara–Tarapur Expressway, 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.
