VELLORE, TAMIL NADU - Work has commenced on the second and final phase of a pedestrian subway near Green Circle on the Chennai-Bengaluru Highway (NH-48) in Vellore, a development aimed at enhancing safety. This ₹7.5-crore project, undertaken by the National Highways Authority of India (NHAI), signifies an effort to address pedestrian hazards on a major arterial route. The subway's first half is already complete, with the second phase now underway. NHAI officials highlighted the initiative's purpose in "saving precious lives," while corporation officials echoed these sentiments regarding the potential to reduce fatalities. This specific subway is located near the new bus terminus on the service lane of the highway.
Meanwhile, the broader 'Bengaluru-Chennai Expressway (BCE),' also designated as National Expressway 7 (NE-7), continues to progress, albeit with considerable delays. This ambitious project, spanning approximately 262 km, is designed to significantly slash travel times between the two metropolitan hubs and is a key component of the 'Bharatmala Pariyojana.' It is intended to foster industrial and economic growth across Karnataka, Andhra Pradesh, and Tamil Nadu, particularly impacting regions like Ranipet and Sriperumbudur.

ONGOING CHALLENGES PLAGUE MAJOR HIGHWAY PROJECTS
The overall vision for the Bengaluru-Chennai corridor faces significant hurdles, as evidenced by persistent delays. One critical 17-km stretch, the Sriperumbudur-Karapettai section of NH-4 (now NH-48), remains stalled. This segment has seen its contract scrapped for a second time. A dispute over fly ash supply reportedly led NHAI to secure a new contract for this particular segment. Officials project that travel between Chennai and Bengaluru could remain arduous for at least another 18 months, with an estimated completion timeline for certain projects extending to October 2026. These delays are occurring despite substantial toll collections, with over ₹140 crore reportedly gathered annually from plazas at Sriperumbudur and Kancheepuram. Official data indicates that more than 110 accidents occur annually on this route, a statistic that authorities hope safety infrastructure like the new subways and planned foot overbridges will help mitigate.
SAFETY MEASURES AND DEVELOPMENT AMBITIONS
Beyond the subway in Vellore, NHAI has announced plans to construct five additional foot overbridges (FOBs) in identified high-risk accident zones within the Vellore district. These locations include Poigai, Vasur, Melmanavur, Vallalar Nagar, and Rangapuram, areas experiencing considerable foot traffic that creates hazardous road crossings. Each of these FOBs is projected to cost around ₹1.8 crore and will feature staircases on either side. These initiatives are presented as measures to curb jaywalking, reduce accidents, and ensure smoother traffic flow on NH-48.

The Bengaluru-Chennai Expressway, when fully realized, is expected to act as a catalyst for real estate and industrial expansion. It is envisioned as a high-speed corridor that will unlock new opportunities for residential, commercial, and industrial development along its path, ultimately aiming to boost logistics efficiency.
PROJECT DECONSTRUCTION AND CONTRACTORS
The sprawling Bengaluru-Chennai Expressway project is broken down into various phases and packages, involving numerous contractors.
Phase 1 (Karnataka): Includes packages from Bangalore to Bethamangala, with contractors like Dilip Buildcon Ltd. and Montecarlo Ltd. involved.
Phase 2 (Andhra Pradesh & Tamil Nadu): Encompasses stretches from Bethamangala to Bangarupalem, with APCO Infratech Pvt. and Montecarlo Ltd. (MCL) listed as contractors.
Phase 3 (Tamil Nadu): Covers sections from Gudipala to Sriperambadur, involving contractors such as Montecarlo Ltd. (MCL), DP Jain & Co. Infrastructure, and Ramalingam Construction Company (RCC).
Phase 4 (Chennai, TN): Details for this phase, including DPR preparation, were handled by VAX Consultants – L&T Infrastructure Engineering Ltd.
The Chennai-Bengaluru Highway (NH-48), formerly known as NH-4, serves as a critical artery connecting two major South Indian cities. The ongoing infrastructure development, including the expressway and localized safety measures like pedestrian subways and overbridges, represents a multifaceted approach to improving connectivity and safety, though the pace of progress remains a point of contention.
