The NHSRCL has completed 100 km of viaducts for the Mumbai-Ahmedabad High-Speed Rail Corridor project.
Full Span Launching technique (FSLM), where 40 metres long box girders are launched through state-of-the-art launching equipment, is being used along with span-by-span launching of segments.
FSLM is 10 times faster than the launching through span-by-span method, which is normally used for constructing metro viaducts
The viaducts include bridges over six rivers: Par (Valsad district), Purna (Navsari district), Mindhola (Navsari district), Ambika (Navsari district), Auranga (Valsad district) and Venganiya (Navsari district), all in Gujarat.
The installation of noise barriers has already started on the constructed viaduct. The laying of the first Reinforced Concrete (RC) track bed for the MAHSR corridor track system as used in Japanese Shinkansen has also started in Surat.
The J-slab ballastless track system is being used in India for the first time.
While the breakthrough of first mountain tunnel of 350 metre has been completed in Valsad district, first steel bridge of 70 metres length has been erected in Surat district.
This is the first of the 28 steel bridges which will be the part of MAHSR corridor.
The Mumbai – Ahmedabad High-Speed Rail (MAHSR) project is 508 km long and is India’s first High-Speed Rail (HSR) corridor. Out of 508 km, 352 km lies in Gujarat (348 km), and Dadra and Nagar Haveli (four km), and the balance 156 km lies in Maharashtra.
National High Speed Rail Corporation Limited (NHSRCL) has awarded 100 per cent civil contracts for the construction of MAHSR alignment in Gujarat.
The ambitious high-speed corridor has awarded 100 per cent civil contracts for the construction of the MAHSR alignment in Gujarat which constitutes 352 km out of 508 km of the total MAHSR corridor.
NHSRCL has also awarded civil contracts for eight HSR stations at Sabarmati, Ahmedabad, Anand, Vadodara, Bharuch, Surat, Bilimora, and Vapi, and two rolling stock depots at Sabarmati and Surat.
In order to ensure seamless integration with the railways, the Vadodara HSR station is planned above the existing platform No-7 of Vadodara station of Indian Railways. With this integration, the passengers will get the comfort of easy transfer between HSR and Indian Railways.
The construction work is in progress in Gujarat and Dadra & Nagar Haveli. Out of 352 km, geotechnical investigation work has been completed on 325 km length. For doing the geotechnical investigation, Asia’s largest geotechnical lab has been developed at Surat.
Work on piles, foundations, piers, pier caps, casting, and erection of girders for viaducts and stations has started, all along the alignment passing through eight districts of Gujarat.
The Mumbai-Ahmedabad bullet train is being funded with a loan from the Japan International Cooperation Agency (JICA). The total project cost is Rs 1.1 lakh crore which is slated to increase more than Rs 1.5 lakh crore due to delay.
