National Expressway 7, Under construction expressway in Karnataka and Tamil Nadu, India
National Expressway 7 is a high-speed corridor being built to connect Bangalore's outskirts with areas near Chennai, passing through the Andhra Pradesh region. The route includes multiple lanes with grade-separated intersections designed to handle heavy vehicle traffic without disrupting local roads.
This expressway was initiated as part of India's national highway expansion program to improve connectivity between major economic centers in the south. The project represents a shift toward modernizing road infrastructure across the region.
The expressway traverses through diverse regions connecting technology centers, industrial zones, and traditional agricultural areas across three states in southern India.
The route crosses varied terrain from hillsides to plains, with conditions that change seasonally. Check in advance which sections are open, as different parts complete at different times.
Six different construction companies simultaneously work on ten separate construction packages divided into three phases across the expressway's length.
