8. India’s Longest Expressway – Delhi-Mumbai Expressway
   Covering 1,380 km across six states, this expressway halves the travel time between Delhi and Mumbai. With green features like EV lanes and trauma centers, it sets new standards for highway design. Record-breaking construction milestones highlight its scale.
9. Asia’s Longest Bi-directional Tunnel – Zojila Tunnel, J&K
   Stretching 14.15 km through the Himalayas, the Zojila Tunnel will provide all-weather access between Srinagar and Leh. Once finished, it will reduce travel time from 3.5 hours to 15 minutes. It’s a crucial development for military logistics and civilian mobility.
10. World’s Highest Tunnel Above 10,000 ft – Atal Tunnel, Rohtang
    The 9.02 km Atal Tunnel runs beneath Rohtang Pass and is operational year-round. It cuts Leh travel time by 5 hours and supports military and economic activity. Its construction in extreme conditions showcases Indian engineering grit.
11. India’s First Vertical-Lift Rail Bridge – Pamban Bridge, Tamil Nadu
    This new sea bridge allows ships to pass beneath by lifting a central span. Running parallel to the old Pamban Bridge, it modernizes a historic route. It's a blend of tradition and cutting-edge engineering.
12. India’s First Cable-Stayed Rail Bridge – Anji Khad, J&K
    This bridge is part of the critical Udhampur-Baramulla rail link. Built in a seismic zone with tough terrain, it uses cable-stayed technology for stability. It's a first-of-its-kind for Indian Railways.
13. India’s Longest Rail-Road Bridge – Bogibeel Bridge, Assam
    At 4.94 km, this bridge connects Assam to Arunachal Pradesh with a rail line below and a highway on top. It enables faster movement of goods and people, improving border area access. It's earthquake-resistant and aids both defence and development.
14. India’s Longest Sea Bridge – Mumbai Trans Harbour Link
    At 22 km, this bridge connects South Mumbai to Navi Mumbai in just 20 minutes. Designed for 70,000 vehicles daily, it overcomes seismic and environmental challenges. It improves airport access and boosts real estate development.
15. World’s Highest Railway Bridge – Chenab Bridge, J&K
    Soaring 359 m above the Chenab River, this bridge is a marvel of rail engineering. Part of the Udhampur-Baramulla link, it ensures all-season rail connectivity to Kashmir. Built to withstand earthquakes and winds, it's a symbol of national unity.
16. World’s Tallest Railway Bridge Pier – Jiribam-Imphal Line, Manipur
    Pier P-4 of Bridge No. 164, towering at 141 meters, holds the title of the world’s tallest railway bridge pier – a feat that surpasses even the height of the Qutub Minar. Located on the Jiribam-Imphal railway line, this engineering marvel is part of a broader effort to connect Manipur and the rest of the Northeast to India’s national rail network.
17. India’s Largest Nuclear Power Plant – Kudankulam, Tamil Nadu
    With over 6,000 MW capacity, Kudankulam is India's most powerful nuclear facility. It strengthens the grid with clean, base-load energy and deepens Indo-Russian cooperation. Its design supports carbon goals under the Paris Agreement.
