The project’s biggest setback came from a basic lapse — construction started before acquiring all required land. Within a year, residents of Nangli Razapur objected, halting work on a crucial stretch and exposing gaps in initial planning.

The dispute over around 8.5 acres of land dragged on from 2016 to 2023. Continuous back-and-forth between authorities and landowners stalled progress, leaving a 700-metre stretch and a key pillar incomplete for years.

The land, classified as riverine, had a notified rate of Rs 17 lakh per acre, while owners demanded Rs 3 crore. The disagreement led to prolonged negotiations, social impact assessments, and eventual settlement only in 2024.

Nearly a decade after project approval, officials identified about 300 trees along the alignment. This late discovery meant fresh surveys, compliance, and permissions, further delaying construction timelines.

Permissions under the Delhi Preservation of Trees Act and approvals from the Central Empowered Committee took time. Even after reassessment reduced tree cutting to 85, approvals for around 170 trees only came in July 2025.

Critical elements like high-tension lines, land conditions, and alignment challenges were not fully assessed beforehand. These had to be addressed during construction, leading to repeated interruptions and revisions.

Building across the Yamuna floodplain required deep foundations of up to 50 metres and massive wells of 14 metres in diameter. Flooding risks and even a suspected pier tilt added to delays and technical difficulties.

The Covid-19 pandemic disrupted labour and logistics significantly. Between 2019-20 and 2022-23, progress barely moved from about 80% to 82%, highlighting the extent of slowdown.

In August 2021, small sections were inaugurated despite the project being far from complete. This pattern of multiple inaugurations created a perception of progress without delivering full commuter benefits.

The delay added an estimated Rs 400–600 crore to project costs. However, the real burden is far higher, including fuel wastage, pollution, lost productivity, and daily commuter stress due to prolonged congestion.
