NCRTC installs 360 metre long steel spans on Delhi-Meerut RRTS corridor

The NCR transport corporation has installed six steel spans with a combined length of around 360 metres for crossing the Ghazipur drain and Kondli roundabout on its upcoming Delhi-Meerut RRTS corridor.

The National Capital Region Transport Corporation (NCRTC) has installed six steel spans with a combined length of around 360 meters for crossing the Ghazipur drain and Kondli roundabout on its upcoming Delhi-Meerut RRTS corridor. These steel spans have been installed one after the other, making it the only place on the entire RRTS Rapid Rail Transit System corridor where such a long viaduct is being constructed with special steel spans.

Construction Challenges

The NCRTC usually erects pillars at an average distance of 34 meters for the construction of an elevated viaduct of the RRTS corridor. These pillars are joined by pre-cast segments with the help of a launching gantry to form the RRTS viaduct span. However, in some complex areas where the corridor is crossing rivers, bridges, rail crossings, metro corridors, expressways, or other such existing infrastructure, it is practically not possible to maintain this distance between pillars. Therefore, steel spans are used to connect the pillars in such situations.

Significance of Steel Spans

The installation of steel spans is a significant milestone in the construction of the Delhi-Meerut RRTS corridor. These spans will enable the corridor to cross the Ghazipur drain and Kondli roundabout, which are key obstacles in the path of the project. The use of steel spans in these areas will also help to minimize the impact of construction on the existing infrastructure and traffic.

Project Details

The 82-km long Delhi-Ghaziabad-Meerut RRTS corridor has a 70-km long elevated section. The corridor is expected to be completed by 2025 and will provide a high-speed rail connection between Delhi and Meerut. The project is being funded by the Government of India and the World Bank.

The installation of steel spans on the Delhi-Meerut RRTS corridor is a testament to the NCRTC's commitment to completing the project on time and within budget. The use of innovative construction techniques, such as steel spans, will help to ensure that the corridor is built to the highest standards of quality and safety.
