CRRI suggests fixes for 60 Lutyens' Delhi roads
At least 61 out of 79 avenue roads in Lutyens' Delhi area have been found to be in need for maintenance and rehabilitation, according to a survey report by the Central Road Research Institute (CRRI). The survey — carried out in January and February this year — included 79 avenue roads across five divisions in New Delhi.
Issues such as cracks, distressed services, and weathering were found in the survey and the report has recommended milling and overlaying in case 60 crucial roads, such as outer circle of Connaught Place, Sansad Marg, Janpath, KG Marg, and Lodhi Estate, among others.
'CRRI has suggested several measures including correction of slope to prevent waterlogging, surface removal of road from 40-50mm up to 150-160mm in case of heavily damaged surface. We will be preparing project reports and issue tenders based on these findings. Roads with higher level of damage will be prioritised,' a senior official of New Delhi Municipal Council (NDMC) said.
According to the proposal cleared by the council in August 2024, NDMC will spend ₹4.72 crore on the CRRI road study and improvement project. This does not include the cost of repairing the roads. In September, the council signed an agreement with CRRI for studying and improving the road infrastructure in New Delhi. Under the agreement, the CRRI is to help the civic body in structural evaluation of its roads, supervise the construction quality, and help in training of engineers and staff members and engineering divisions, an official said.
According to the CRRI report, also seen by HT, eight roads were surveyed under the Connaught Place division, all of which have been found in need for rehabilitation measures. The poorest condition was found at Panchkuiyan road extension which was found to have longitudinal cracks, so the report recommended 90-100mm milling and 90mm overlaying.
'Road milling or asphalt milling is a process used in road construction to remove a layer of existing asphalt pavement. This process is essential for preparing the road surface for new asphalt paving. The overall level of the road does not increase at the end of the process,' an official explained. At Sansad Marg, the road found to be distressed near CP and cracks were observed on Janpath road, the report said.
Notably, the survey covers the CP, R1, R2, R4 and R5 divisions. The R3 division include Netaji Nagar, Nauroji Nagar, and A to J Avenue in Netaji Nagar Colony. Many of these areas are undergoing redevelopment under General Pool Residential Accommodation (GPRA) projects.
In CP's outer circle, CRRI found cracks at approaches and muddle lanes while the KG Marg has 'hungry surface' with micro cracks. Hungry surface is referred to a condition with loss of aggregates from the surface or the appearance of fine cracks.
In the R1 division, 18 NDMC roads were assessed and only four — Pandara Road, Purana Quila Road, Jai Singh Road and Bhagwan Das Road — were found to be in good condition and no intervention is required on them. The Janpath road from CP to Dr RP Road was found to be heavily cracked with slight depressions. 'Dr RP Road is heavily distressed due to NBCC constructions. Concrete deposits were also found and drainage needs to be improved,' the report stated.
Similarly, in the R2 division, the Golf Link Colony road was found to be heavily ravelled due to weathering with potholes and undulated surface. The CRRI has recommended that the road level has to be reduced due to drainage issues.
In the R4 division, 28 roads were surveyed and the maximum damage was found at Bordoloi Road. Further, patches and long cracks were found on the Sardar Patel Marg and 50-60mm milling has been recommended.
Under the R5 division, three out of four roads including Mandir Marg, Kali Bari Marg and Pandit Pant Marg were found to be in need for rehabilitation while only the Talkatora road is in good condition.
An NDMC official said that most of the roads in New Delhi have completed a lifespan of five years but the extent of cracks varies, depending on location, usage, heavy vehicle movement and local conditions like drainage issues.

A Gap Too Loud: Damaged Barriers Fail To Screen Noise, Turn Eyesore
New Delhi: To protect people living along the flyovers on Outer Ring Road from the constant noise of passing traffic, particularly at night when heavy trucks rumble along this route, noise barriers were installed a few years back. Due to lack of maintenance, huge gaps are now visible in what was supposed to be an impregnable wall that would block the sound. Sections have either disappeared or are damaged. Besides being an eyesore, these barriers are no longer serving their purpose. If any visitor to the city drives down this route, after landing at Delhi airport, the experience can hardly be pleasing to the senses. His cab will cross a series of flyovers that have these fractured noise barriers installed on both sides looking quite grim. The Rao Tula Ram, Munirka and Africa Avenue flyovers now have empty frames at many places and sheets that are coming off, flapping dangerously when the wind blows. Installing these barriers along both sides of the flyover had, according to one estimate, cost around Rs 40–50 lakh, said a PWD source. "Theft is the biggest problem. People steal the sheets and railings, anything they can sell. Storms too inflict a lot of damage. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Click Here To Read More - micro segmentation software Expertinspector Click Here Undo We try to replace them when we can. PWD is always keen on maintaining aesthetics and we will undertake repairs on this stretch soon," said the source. Residents say they have been waiting for this to happen. "It's not just the noise. If you're driving from the airport at night, the headlights from the RTR flyover, which is at a height, shine straight into your eyes," said Jaspreet, a Vasant Vihar resident. "Our homes shake when heavy trucks pass by. It's like sleeping on a railway track," added Suresh Goel of the Vasant Vihar Federation of RWAs. Another resident added: "The sound levels are high and cause noise pollution. Opening windows is impossible and using open areas at our home not feasible." Dr Nasim Akhtar, chief scientist at Central Road Research Institute (CRRI), says the so-called "noise barriers" are mostly just "view-cutters" and don't do the job of reducing noise anyway. "These are not proper barriers," he says. "For a noise barrier to be effective, you need two things: strong columns or posts that can hold the structure, much like a photo frame, and high-quality panels (which is the photo itself) that can absorb or reflect sound. If the columns are weak, the barriers can't last. That's why you see them breaking so often. Even when they are installed, they don't reduce noise properly, which means high maintenance costs." He added that CRRI had provided the design for noise barriers on five flyovers (Madhuban Chowk to Mukarba Chowk, Mangolpuri to Mukarba Chowk, Prembari to Azadpur, Vikaspuri to Meera Bagh and Vasant Vihar) which guarantees that the structure would remain in place for at least 20 years. "But that hasn't been implemented yet. The focus should be on proper design," he emphasized. Dr Akhtar pointed out that PWD uses multiwall polycarbonate sheets for the barriers. While this material is often used for soundproofing walls, it's not the best choice. The ideal material, according to him, is PMMA (polymethyl methacrylate), which is stronger, more durable and better at blocking noise. PMMA is a transparent plastic commonly used for sound barriers installed along roads, railway tracks and airports. Experts point out that it's a serious pollution issue too. Vivek Chattopadhyay, principal programme manager (Clean air and sustainable mobility), Centre for Science and Environment, said, "For all public infrastructure, SOPs, responsibility and action taken reports should be part of the regular activity. So, noise barrier installation must be addressed on a priority basis because persistent traffic noise is a major pollution issue and affects residential areas, schools, hospitals and even other commuters. Creating and installing them should always be accompanied by an SOP and maintenance protocol along with accountable agencies." He added, "Further, in consultation with CRRI, even more advanced sound-absorbing features, materials and designs should be considered. Also, there should be no unnecessary, habitual honking. Perhaps even noise meters with public displays should be installed at strategic points to make people aware of the safe limits and by how much these are being exceeded; like colour-coded AQI helps people to understand severity.

NDMC to build iconic clock tower at Talkatora roundabout
NEW DELHI: The New Delhi Municipal Council (NDMC) has finalised a design and prepared the estimates for constructing a clock tower at the Talkatora Roundabout after receiving necessary approvals from the Delhi Urban Art Commission (DUAC) last month. NDMC Vice Chairman Kuljeet Singh Chahal on Sunday informed that a magnificent clock tower will be constructed at the Talkatora Roundabout with the aim of enhancing the visual identity and architectural beauty of Lutyens' Delhi. 'It will be approximately 27 metres tall and feature a 2-metre diameter clock. The structure will have an octagonal design, constructed using RCC (Reinforced Cement Concrete), and will be adorned with a layer of clay bricks,' he said. The surrounding area will feature granite flooring, steel railings, and marble decorations. The estimated cost of the project is Rs 1.3 crore, and the target is to complete construction by December 2025. The project might be tabled in the council meeting for final approval. Chahal stated that most municipal bodies across the country have iconic clock towers as symbols of a city's identity, heritage, and architectural significance, and now NDMC will also develop such a grand architectural landmark. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like They Lost Their Money - Learn From Their Lesson Expertinspector Click Here Undo 'It will not only serve as a new attraction for Lutyens' Delhi but also mark the entry point into the NDMC area from nearby MCD regions such as Rajendra Nagar and Karol Bagh. There will be internal stairs constructed at the facility to enable maintenance and repairs. For safety, railings will be installed around the tower, and the base will be decorated with marble,' stated the Vice Chairman while adding that the project reflects the national mission of beautifying Indian cities and preserving cultural heritage. Earlier, the NDMC got the soil of the proposed location tested for building the clock tower via a private agency at the proposed site (Talkatora Roundabout), and the soil was found suitable for building the clock tower structure. 'Since construction of the tower required amendments in the layout plan, NDMC sent an updated proposal to DUAC for approval. The agency took some specific details, including technical ones, about the Ghantaghar layout plan from NDMC, and gave consent in April,' said an official earlier. NDMC initiated a search for a suitable location to erect a clock tower following Lieutenant Governor VK Saxena's inspection in April. Previously, the 'New Delhi Town Hall' featured a clock tower atop its headquarters, but the structure was demolished in the 1980s to make way for the present NDMC building.

Why does Delhi's local train system lie in ruins?
The story so far: While the Delhi metro has recently announced a facility to buy QR tickets on 11 different apps, the Delhi suburban Railway, often referred to as the Delhi local, lies derelict. When did the system start? Delhi got its local train service in the first decade after Independence. On January 2, 1955, Delhi's first local train ran from New Delhi station to Sarojini Nagar, then known as Vinay Nagar. The network then gradually expanded to connect Delhi with its neighbouring cities. Today, the suburban system links seven key hubs across the National Capital Region (NCR) — from Sonipat, Bhiwani, Rewari and Palwal in Haryana to Meerut, Ghaziabad, and Aligarh in Uttar Pradesh — with Delhi at its centre. What is its current state? Built to serve suburban commuters, this network was meant to ease traffic and support daily travel. But in reality, it's overcrowded, unreliable, and neglected. According to Dr. Velmurugan Senathipati of the Central Road Research Institute, despite its wide reach — especially in NCR's rural areas — the Delhi local carries just 0.5% to 3% of commuter traffic, far below the ideal 6-7%. Passengers report waiting over an hour, 15 times longer than the metro, only to board jam-packed coaches. Sarita Sethi, a government employee commuting from New Town, Faridabad to Okhla, states, 'My commute should ideally be 25 minutes but it's always nearly an hour long due to unscheduled halts as express trains are prioritised.' Nikhil, a railway employee, says, 'There are too many passengers and too few trains. Forget about sitting, during evenings, you can't even stand in the train.' Unlike the Metro, enforcement of women-only coaches is lax in the local. Mrs. Sethi says, 'Men often enter the ladies coach brazenly. Safety and theft are constant concerns. When the train's late in the evenings, the journey from the station to home can easily become a nightmare.' Dr. Velmurugan's study confirms this insecurity, as women make up just 14.6% of local train passengers. Is the metro a better alternative? The local train service in Delhi is much more affordable than the metro. Dr. Velmurugan's research shows that nearly 40% of suburban rail passengers earn less than ₹5,000 a month. For them, the local train is not just a choice, it's the only option they can afford. A local train ride from Greater Noida to Delhi costs just ₹15, compared to ₹90 by metro or ₹69 through a bus-metro combo, excluding last mile connection fares. Over a month, that's ₹750 by the local versus a staggering ₹4,500 by metro. Moreover, a Monthly Season Ticket (MST) brings costs down to just ₹270 a month or ₹9 a day. Additionally, local trains have a dedicated vendors' bogey, widely used by dairy farmers to transport produce to markets like Sadar Bazaar and Chandni Chowk. But even this advantage is fading. Amit, a dairy farmer from Ajayabpur village in Greater Noida, says, 'We had to stop using the local because delays were spoiling the produce. My friends now either rely on road transport or have quit the trade altogether, it just isn't profitable anymore.' These concerns have driven passengers to explore more reliable — though far costlier — alternatives, such as private buses or personal vehicles. Railway officials have noted a sharp decline in the issuance of MSTs, a clear sign that even loyal users are abandoning the system. What should be done? Dr. Velmurugan states, 'the local isn't a replacement for the Metro, it should complement it. It can act as a feeder service across NCR's rural areas where the Metro can't go. Plus, it's cheaper to build. There needs to be resonance, not a race,' he explains. Dr. Velmurugan suggests better scheduling, increased frequency, newer train sets, and most importantly, dedicated tracks. These changes, he says, could revive the system. But there are no such official modernisation or renovation plans in the offing as of now.
