The document summarizes India's highway planning and development over time. It discusses key committees and plans that guided highway development since the early 20th century. The Nagpur Plan from 1943 was the first to classify roads into categories like national highways, state highways, and rural roads. Subsequent plans like the Bombay Plan and Lucknow Plan aimed to increase road density and connectivity across the country. Current visions like the Rural Road Vision 2025 plan to fully connect villages through new roads. Going forward, large investments are planned over 20 years to expand the national highway network and expressways while addressing environmental pollution from increased road traffic.
