As per NHAI and Indian Roads Congress, expressways are access controlled highways with a divided carriageway, designed for high speed vehicular movement and heavy traffic.^[1] There is a central reservation or median that separates the flow travelling in opposite directions. Entrance and exits are provided only by grade separated interchanges. The interchanges may be system interchanges (such as cloverleaf, three-way, trumpet) used with other national or state highways or be service interchanges (such as SPDI) used with smaller roads.^[2] In contrast, National highways may or may not be divided by a median and may or may not have access control.^[3] Some highways, built by State Governments, which may be fully access controlled or may be limited access controlled, are declared or named as expressways by their respective State Governments.^[4]
