The worsening traffic between Sarai Kale Khan and Ashram is not simply the result of too many vehicles on an important Delhi road. It is also the visible outcome of several major transport projects being built, expanded and connected within the same corridor without a demonstrated, integrated assessment of how their traffic would interact. Railway, metro, RRTS, interstate bus, expressway, flyover and elevated-road infrastructure now converge across a limited urban network, leaving vehicles released by one project to encounter congestion created by another.
The problem is concentrated in a corridor that has become one of Delhi’s most important interchange zones. Sarai Kale Khan brings together a railway station, a metro station, the RRTS system and an interstate bus terminal. The Ring Road, Barapulla corridor, DND, Delhi-Mumbai Expressway and Ashram Flyover add further streams of traffic. Each facility serves a distinct transport purpose, but their combined effect is experienced by commuters as one connected road system.
That distinction matters. A flyover or corridor can be assessed as a project in isolation and still worsen congestion at the next junction. The report indicates that this is happening repeatedly between Sarai Kale Khan and Ashram. Traffic arriving from Mayur Vihar and east Delhi now adds to the flow through Sarai Kale Khan, while passengers using the railway station, metro, RRTS and bus terminal generate private vehicles, buses, auto-rickshaws and pick-up traffic on the same surface network.
The result is a classic network problem: capacity added at one point is not necessarily capacity added to the entire route. After Barapulla Phase 3 became operational, expectations were that pressure on the Ring Road in front of Sarai Kale Khan would ease. Instead, traffic from the new link has fed into an already crowded corridor. The report suggests that the project’s effect cannot be judged only by whether vehicles move faster on the new section. It must also be assessed by where those vehicles enter, merge, turn and eventually stop.
The Ashram intersection illustrates the difficulty. Traffic from the DND, Delhi-Mumbai Expressway, Barapulla-1 and Barapulla Phase 3 meets traffic moving between Sarai Kale Khan and Ashram. Vehicles travelling from the Delhi-Mumbai Expressway towards Lajpat Nagar use the Ashram Flyover side, while traffic from Sarai Kale Khan and Barapulla moves towards Ashram. These movements intersect within a constrained road environment, creating conflict between directions rather than a smooth distribution of flows.
A missing connection makes the arrangement more complicated. Vehicles travelling from the Delhi-Mumbai Expressway towards the DND reportedly do not have a direct route. They are required to approach the area near the Sarai Kale Khan bus terminal, pass under the flyover and take a U-turn. Such movements add traffic to the main carriageway even when the vehicle’s intended journey is between two major links. The absence of a direct connection therefore creates additional turning traffic at a location already handling several transport systems.
The pressure continues near the Gurudwara on another part of the Ashram turn. Traffic from Ashram, vehicles arriving from the Ashram Extension Flyover towards Lajpat Nagar, and flows from the Delhi-Mumbai Expressway and DND converge at one location before moving towards Sarai Kale Khan. Some of this traffic also adds pressure to the road towards ITO. The corridor consequently functions less like a sequence of independent junctions and more like a chain of interdependent merges.
The Barapulla Surya Ghadi cloverleaf presents a separate capacity mismatch. According to the report, three lanes from Barapulla Phase 3 merge into a two-lane cloverleaf. The resulting five lanes then reduce to three lanes towards Barapulla-1. This kind of sudden reduction creates a bottleneck because the downstream section cannot process the volume arriving from the upstream links at the same rate. The congestion is not necessarily caused by one badly designed road element; it emerges from the relationship between lane supply, traffic direction and downstream capacity.
This is why the experts quoted in the report do not identify a single junction or flyover as the complete solution. Dinesh Kumar, a former chief engineer in the Public Works Department, said that a connection allowing the Meerut Expressway to bypass Sarai Kale Khan and link towards the Ashram Extension Flyover could have reduced today’s pressure had it been provided when the expressway was planned. His observation points to a planning decision that affects how traffic is distributed across the wider network.
Dr S. Velmurugan, a former senior scientist at the Central Road Research Institute and senior adviser at the National Council of Applied Economic Research, attributed a significant part of the problem to a lack of coordination between government agencies. He said that addressing only one junction, flyover or road would not resolve the problem and called for a comprehensive traffic study covering the entire Sarai Kale Khan-Ashram area.
Transport expert Anil Chhikara similarly said that such a study should include traffic linked to the railway, metro, RRTS, interstate bus terminal, Barapulla Phase 3, DND, Delhi-Mumbai Expressway and Ashram Flyover. The first requirement, in his view, is to establish how many vehicles arrive from each direction, when pressure is highest and where different movements conflict. Only then can an integrated traffic plan be prepared for the corridor.
The institutional issue is as important as the engineering issue. The corridor contains assets associated with different agencies, transport modes and project timelines. Rail and metro infrastructure may be planned around passenger access, while expressways and flyovers are designed to move vehicles through the city. Bus terminals generate stopping and pick-up activity, while arterial roads must absorb through-traffic, local traffic and turning movements. Without a shared model of these combined flows, every agency can complete its own project while the public experiences a worsening overall system.
The report does not establish that a single authority is solely responsible for the congestion, nor does it provide traffic counts, travel-time comparisons or a formal government assessment of the corridor. That absence is itself significant. The experts’ call for a consolidated study indicates that the first missing piece is not another isolated construction intervention but a common evidence base. Traffic volumes, peak periods, lane transitions, turning patterns and interchange activity need to be examined together rather than project by project.
For commuters, the institutional fragmentation appears as delay, forced U-turns, competing traffic streams and bottlenecks near major public transport facilities. For city planning, the Sarai Kale Khan-Ashram stretch demonstrates the limits of treating connectivity as the simple addition of new links. A corridor can gain more roads and still lose operational efficiency if those links are not designed as part of one network.
The evidence currently supports a clear conclusion: transport capacity in this part of Delhi has been expanded through multiple projects, but the interaction between those projects remains inadequately coordinated. What remains to be established is the precise contribution of each traffic stream and which interventions can reduce conflict without shifting congestion to the next junction. The next meaningful step, according to the experts cited, is a comprehensive corridor-wide traffic study followed by an integrated operating and design plan.
