The Delhi-Meerut Regional Rapid Transit System (RRTS) corridor will not only pass through the Delhi-Meerut road but also across rivers, bridges, rail crossings, expressways. It would use special spans over the gaps where the corridor has to cross over the structures. The corridor is being constructed by the National Capital Region Transport Corporation (NCRTC), having 82 km length and 70 km of the elevated corridor. The two customised special spans will be used between Sahibabad and Ghaziabad. According to a spokesperson of NCRTC, to construct the elevated corridor of RRTS, NCRTC will use erecting piers at a distance of about 34 m. He said that maintaining the distance between the piers is not possible in areas like over the river, bridges, railway crossings, expressways, metro corridors, or other infrastructures. The corridor project is likely to be completed by 2025. He said that the special spans between Sahibabad and Ghaziabad would have a customised shape, size, design, elevation and weight. One span will be set up at Vasundhara of 73 metres and weighing 850 tonnes to cross the rail crossing. NCRTC is taking all measures to ensure the services of the Indian Railways so that the construction work is not interrupted and gets completed on time. The Delhi Metro Rail Corporation has used concrete and steel spans while constructing a pillar to support the elevation. The longest one is the 100 metres at Okhla in South Delhi to cross four railway tracks. He said that NCRTC is building these spans in the factory, which is then transported to the construction sites at night to avoid traffic congestion and get assembled systematically. The size and structure of these spans are designed in advance according to the requirements of the construction. The corporation has constructed about 900 piers and 10 km of the viaduct, located mostly in the 17 km priority section between Sahibabad and Duhai, which is likely to be commissioned by March 2023.
