10 recent engineering marvels of India

The 9.02-kilometre Atal Tunnel connects Manali to Lahaul-Spiti Valley in Himachal Pradesh, reducing the travel distance by 46 kilometres and time by 4-5 hours. Completed in 2020, it is named after former Prime Minister Atal Bihari Vajpayee and is a significant engineering achievement.A cable-stayed bridge, it is one of the longest in India. The construction of this bridge in Mumbai required innovative techniques to manage the challenging marine environment and geological conditions.The use of seismic arresters allows the bridge to withstand earthquakes of up to 7.0 magnitude on the Richter scaleThe Pir Panjal Railway Tunnel is the longest railway tunnel in India, located in the Pir Panjal Range of the Himalayas. It was constructed using the New Austrian tunnelling method. The tunnel was inaugurated in 2013 and has significantly reduced travel time between Jammu and Srinagar.The longest road bridge in India, the Dhola-Sadiya Bridge is a 9.15-kilometer-long bridge in Assam which spans the Brahmaputra River. It provides an important transportation link for the Indian Army and has opened up new opportunities for trade and tourism in the region. The bridge was constructed using the latest technology and engineering techniquesThe Chenab Bridge, expected to be completed soon, is being built by the Indian Railways. It will be the world's highest upon completion and will connect two regions in Jammu and Kashmir. Built in a challenging terrain and weather conditions, it will be a 1.315-kilometer-long steel arch structure supported by piersThe Bogibeel Bridge is a combined road and rail bridge located in Assam, which spans the Brahmaputra River and is the longest rail-cum-road bridge in India, with a length of 4.94 kilometres. Inaugurated in 2018, the bridge has a double-decker structure and is built to withstand natural disasters such as earthquakes and floods.Inaugurated in 2019, Durgam Cheruvu Cable Bridge is a cable-stayed bridge that spans the Durgam Cheruvu lake in Hyderabad. It is suspended by cables from a single pylon that stands 49 metres tall. The bridge's unique design and construction required advanced engineering techniques. The Statue of Unity is a statue of Sardar Vallabhbhai Patel located in the Indian state of Gujarat. It is considered an engineering marvel and is the tallest statue in the world, standing at 182 metres. The statue involved complex engineering techniques during its construction to ensure stability.The upcoming Pamban Bridge is a proposed railway bridge in Tamil Nadu, connecting Rameswaram island and mainland India that will replace the existing Pamban Bridge. With a 72-metre-long lift span, it will be India's first vertical-lift bridge and will allow for the passage of taller ships. The Signature Bridge located in Delhi spans the Yamuna River. The bridge is 675 metres long and 35 metres wide, with a 154-metre-high pylon that serves as an observation deck for visitors. Inaugurated in 2018, it has several modern technologies, including sensors to monitor wind speed and traffic
