Delhi's transport network gets major boost: Metro expansion, highway upgrades accelerate this week

Delhi's transportation landscape is shifting rapidly as multiple high-stakes infrastructure projects crossed critical milestones this week, signalling an aggressive push to ease the city's chronic congestion woes.

The Delhi Metro Rail Corporation announced on Monday that Phase IV expansion work on the Purple Line—connecting Aerocity to Inderlok through central Delhi—has reached 62% completion. The 59-kilometre corridor, which will serve high-traffic zones including Gurgaon, Sikanderpur, and East Delhi, is now expected to become operational by late 2027, six months ahead of the original timeline. Officials attributed the acceleration to improved contractor coordination and streamlined land acquisition processes along the Mehrauli-Badarpur corridor stretch.

The announcement comes as the Delhi Development Authority released updated projections showing that the entire Metro network could expand from the current 389 kilometres to 453 kilometres within three years—a 16% increase that would add seven new lines and 86 new stations across peripheral areas like Rohini, Dwarka, and Greater Noida regions.

Meanwhile, highway infrastructure also showed movement. The Rs 2,850-crore Dwarka Expressway project, which connects central Delhi to Gurgaon via NH-8, reported completing 78% of its construction. The six-lane expressway aims to reduce travel time between Dwarka and Gurgaon from the current 90 minutes to approximately 30 minutes, potentially alleviating pressure on the already-congested Delhi-Gurgaon corridor that handles roughly 2.2 million vehicles daily.

However, challenges persist. Officials from the Public Works Department noted that ongoing land disputes in Bijwasan and Chattarpur have stalled final stretches of the elevated highway, affecting an estimated 3-kilometre segment. The disputes involve approximately 45 property owners in the region, with compensation negotiations still ongoing.

The transport ministry also flagged concerns about the Bus Rapid Transit system's operational efficiency. Current average speeds on corridors like the one on Ring Road and Ashram Avenue remain below 18 kilometres per hour during peak hours—well short of the 25 km/h target—due to mixed traffic and inadequate enforcement of bus lanes.

For daily commuters, these projects represent a significant shift. Daily passenger volumes on Delhi Metro already exceed 6.7 million, straining existing capacity. The infrastructure push reflects the government's acknowledgment that the city needs substantially expanded mobility options.

As construction accelerates across multiple fronts, residents of outer zones like Rohini and Dwarka are watching closely—their neighbourhood connectivity depends directly on how quickly these projects reach completion gates.
