Mumbai-Ahmedabad bullet train: 100 km of viaducts, 230 km pier work completed
Mumbai, Nov 23 (PTI) The National High Speed Rail Corporation Limited building the Mumbai-Ahmedabad bullet train corridor said on Thursday that 100 kilometres of viaducts and 230 kilometres of pier work had been completed for the ambitious project.
The milestone of construction of 100 km of viaducts has been achieved through launching of 40-metre long 'full span box girders' and 'segmental girders', the NHSRCL said.
Railway Minister Ashwini Vaishnaw uploaded a video on X, formerly Twitter, to inform about the feat.
According to NHSRCL, the viaducts include bridges over six Gujarat rivers, namely Par and Auranga in Valsad district, as well as Purna, Mindhola, Ambika and Venganiya in Navsari district.
'The first girder of the project was launched on November 25, 2021, while the first kilometer of viaduct was ready in six months on June 30, 2022. It achieved construction of 50 kilometres of viaduct on April 22, 2023 and, thereafter, in six months 100 kilometers of viaduct were completed,' the NHSRCL said.
'The Full Span Launching technique (FSLM), where 40-metre long box girders are launched by state-of-the-art equipment, is being used along with span by span launching of segments. FSLM is 10 times faster than the span by span method, which is normally used to build metro viaducts,' it added.
According to NHSRCL, apart from the viaduct work, 250 kilometres of pier work has also been completed for the project, while installation of noise barriers has begun along the constructed viaduct.
'Besides this, the laying of the first reinforced concrete (RC) track bed for the Mumbai Ahmedabad high speed rail corridor track system as used in the Japanese Shinkansen has also started in Surat,' the NHSRCL informed.
The total cost of Mumbai-Ahmedabad High Speed Rail Corridor project is pegged at Rs 1.08 lakh crore.
As per the shareholding pattern, the Union government will pay Rs 10,000 crore to the NHSRCL, while Gujarat and Maharashtra are to pay Rs 5,000 crore each.
The rest of the cost is by way of a loan at 0.1 per cent interest from Japan. PTI KK BNM BNM
