Delhi – Ghaziabad – Meerut RRTS Corridor: NCR Transport Corporation Constructs 50 Spans In A Month

Snapshot

The 50 spans of RRTS corridor have been constructed for the 70 km long elevated section of the corridor, most of which is located in the 17 km long priority section.

 

National Capital Region Transport Corporation (NCRTC) has constructed 50 spans in the priority section of the Delhi-Ghaziabad-Meerut regional rapid transport system (RRTS) corridor in December, a record in construction sector.

The approximate length of one span of the elevated portion is considered to be about 34 metres.

We have completed a viaduct more than 1.50 km within 30 days in December, thereby achieving a new milestone, said a senior NCRTC official involved with the construction.

These 50 spans of RRTS corridor have been constructed for the 70 km long elevated section of the corridor, most of which is located in the 17 km long priority section.

For the construction of the elevated viaduct of the RRTS corridor, NCRTC is erecting piers at an average distance of 34 metres.

After erecting piers, these are joined by precast box segments with the help of launching gantries to construct an RRTS viaduct span. The construction of multiple spans turns in to a viaduct for further process of operations.

Keeping in mind the safety and convenience of residents, NCRTC carries out minimum construction work at sites while making extensive use of precast segments.

The official said this is aimed to ensure smooth flow of traffic during construction and make it possible to construct large sections of the viaduct in less timeframe.

The precast segments for the corridor are being casted at RRTS casting yards located at Muradnagar, Ghaziabad, and Shatabdi Nagar, Meerut.

Once casted, these segments are transported to the site by trucks and then lifted with the help of launching gantries.

In December, NCRTC successfully established the first special steel span (bridge) to cross the main line of Indian Railways near Vasundhara, Ghaziabad, which is 73 metres long and weighs 850 tonnes.

Presently, more than 14,000 workers and more than 1,100 engineers are working day and night for the construction of the elevated and underground section of the 82 km long RRTS corridor.

So far, more than 1,100 pillars of the elevated section have been built, about 54 km of foundation and about 15 km of viaduct have been completed. The 17 km priority section between Sahibabad to Duhai is targeted to be commissioned by 2023 and the full corridor by 2025.
