The NBCC (India) Limited has begun construction of a 1.2 km spiral-shaped skybridge at the upcoming Bharat Vandana Park in Dwarka, southwest Delhi, officials confirmed on Saturday. The bridge, which will be supported by nine pylon towers resembling giant trees, is set to become the signature architectural attraction of the park.

According to officials, the base structures of all nine pylons have been completed, and work has now moved to the upper sections, from where the bridge will extend. Rising up to 45 metres, the structure will be the central landmark of the 200-acre park, being developed by the Delhi Development Authority (DDA) and constructed by NBCC.

“The skybridge will offer a 360-degree panoramic view of Dwarka from an 18-metre-high walkway, designed in a flowing spiral pattern. Each pylon will serve as both a structural anchor and a functional core for pedestrian movement. It’s an intricate project requiring advanced engineering and precision,” an NBCC official said.

As per the detailed design basis report (DBR), the bridge will feature nine pylons and eight cable-stayed spans connected in a rhythmic sequence. The pylons are divided into three types: six Type A structures with internal ramps, two Type B pylons with both lifts and ramps, and one Type C pylon rising 45 metres, featuring an observatory deck and lounge at the top.

Constructed from tubular steel with petal-like aluminium panels, the pylons will support a 3.5-metre-wide skybridge connecting them at 18 metres above ground, rising to 19 metres at midspan. The top deck will combine box beams and cantilever sections, suspended by stay cables, while the underside will feature reflective stainless-steel panels, creating a striking “mirror ribbon” effect that visually links all the pylons.

“From above, the bridge will appear as a shimmering spiral, while from below, the pylons will look like towering metallic trees emerging from the landscape,” the official added.

The project, valued at Rs 233 million, includes the design, supply, fabrication, erection, testing, and commissioning of the entire bridge and is targeted for completion within nine months.

Work had initially been delayed due to height clearance issues linked to the nearby airport. However, the civil aviation department granted the required permissions earlier this year, allowing full-scale construction to proceed.

Each pylon will also house ramps, spiral staircases, and lifts, enabling visitors to ascend to the bridge deck. The tallest pylon will include an observatory deck offering panoramic views of Dwarka, while the central cores will feature green walls, irrigation systems, and vertical landscaping.

Every pylon will have a distinct lighting pattern, synchronised through a central control system, making the bridge glow like a “necklace of light” at night.

The Bharat Vandana Park, planned as a large-scale cultural and recreational hub, will include ecological zones, open-air theatres, craft bazaars, food courts, landscaped gardens, and parking areas. A major attraction will be the “Mini India” zone, shaped like the map of India and featuring scaled-down replicas of monuments and cultural landmarks from all Indian states and union territories.

Pedestrian paths and plazas will be laid out to let visitors explore these clusters as a symbolic journey across India.

Although the project was inaugurated by Home Minister Amit Shah in December 2019, progress was delayed due to various challenges. The DDA had earlier asked NBCC to complete the park by July 2025, though officials now believe that timeline may be extended.

Once completed, the spiral skybridge is expected to become a landmark for Delhi, merging engineering innovation, cultural identity, and urban aesthetics into a single architectural statement.
