Chennai Metro Rail Limited (CMRL) plans to study two elevated corridors: Kilambakkam–Chengalpattu, spanning 26.9 km, and Assisi Nagar–Wimco Nagar, spanning 11 km. CMRL has floated bids for consultants to prepare detailed project reports (DPRs), expected to be completed in four to five months after a consultant is selected, likely within three months. Preparing the DPRs is estimated to cost nearly ₹2 crore.

The Kilambakkam extension would follow the proposed 15.46-km Chennai Airport–Kilambakkam stretch, whose DPR is under central review for approval; construction could begin after approval. The Assisi Nagar link in Madhavaram would connect Phase I and Phase II networks. Existing links between those networks include Alandur, Kilpauk, Thousand Lights, Nandanam, Koyambedu and Vadapalani.

By 2048, the Comprehensive Mobility Plan projects peak-hour, peak-direction traffic of 12,471 on Airport–Chengalpattu and 10,647 on Assisi Nagar–Wimco Nagar. Announced July 25, 2026.

20. Nagar constituency includes Kodambakkam, Ashok Nagar, West Mambalam, Pondy Bazaar, C.I.T. Nagar portion, and Vadapalani. Within two years of pedestrianisation, commercial sales rose 15-20% and land value increased up to 20%. Residents cite severe infrastructure bottlenecks from rampant commercialisation. Rising plinth levels and unchecked encroachments increase pressure on sewer and stormwater networks of unchanged capacity, causing frequent overflows. Ambulances and fire tenders struggle to navigate narrow lanes. The newly constructed J. Anbazhagan flyover has done little to ease traffic. Multi-level Pondy Bazaar parking is often non-operational or at full capacity. Residents report uncleared garbage, poor roads, and poster proliferation. Stormwater drain construction on Arya Gowda Road felled trees but failed to prevent rainwater entry; homes suffered waterlogging in December 2023 downpour. MLA J. Karunanithi attributes parking issues to Metro Rail work and notes traffic reduction from online shopping shift. New flyover eases travel from Saidapet to T. Nagar, Kodambakkam, Nungambakkam. One-way traffic near North Usman Road-Bazulla Road signal planned. ₹3 crore annual MLACDS fund used for bus stand and community hall upgrades.

Baashyaam Group acquired 5.8-acre property on Haddows Road, Nungambakkam from Standard Chartered Bank. Land value including registration costs: ₹1,212 crore, reported as largest land deal in Chennai. Deal closed in May 2025, beating Arihant Foundations in bidding. CBRE served as transaction advisor. Baashyaam develops luxury residential projects including Prarthana (ECR), Crowne Plaza site apartments (Alwarpet), The Peak (Ashok Nagar), The Pinnacle (Boat Club).

Tamil Nadu Housing Board (TNHB) is offering space in its new Chennai commercial complexes at ₹88–118 per sq ft, nearly 20% below private rental rates. EPFO and GST are among the first occupants.

TNHB sold its complexes in Chintamani, which housed the old market, and Anna Nagar to government bodies, including the Tamil Nadu Real Estate Regulatory Authority. Seven other complexes are in Ashoka Colony, KK Nagar, Mogappair, CIT Nagar, Arumbakkam, Ashok Nagar, Peters Colony and Besant Nagar. Metro connectivity and central locations have attracted government agencies seeking space. At CIT Nagar, one block is occupied by GST and EPFO has rented multiple floors.

At least a dozen shops on Govindan Road, which connects Ashok Nagar to T Nagar, are struggling because customers cannot enter or exit due to dug-up stormwater drain pits. The work was reported on May 4, 2025.
