Infrastructure – Chennai Port Elevated Corridor Advances as Major Highway Projects Gain Pace
Infrastructure –The Chennai Port-Maduravoyal Elevated Corridor, one of Tamil Nadu’s most significant transport infrastructure projects, has achieved nearly 22 percent physical progress, marking another milestone in its construction. Valued at Rs 5,600 crore, the project is designed to improve cargo transportation between Chennai Port and the city’s western suburbs while reducing pressure on some of Chennai’s busiest roads.
Elevated corridor work progressing steadily
Stretching over 15.5 kilometres, the elevated expressway is being built above the Cooum River, making it one of the country’s most technically demanding urban road projects. Engineers continue to carry out construction in phases, with work advancing despite the complex conditions associated with building above a river channel.
Officials said construction activities along the riverbanks will pause during the northeast monsoon period, typically between September and January. Heavy rainfall during these months makes such operations unsafe, and work will resume once weather conditions improve. According to the current schedule, the elevated corridor is expected to be completed by March 2029.
Faster freight movement expected after completion
Once operational, the corridor will offer a dedicated high-speed connection between Chennai Port and Maduravoyal. The direct route is expected to substantially reduce travel time for container trucks transporting goods to and from the port, improving freight efficiency and supporting logistics operations across the region.
The project is also expected to reduce traffic congestion on several major city roads by diverting heavy commercial vehicles away from existing surface routes. This is likely to improve travel conditions for daily commuters while enhancing the overall flow of traffic within Chennai.
New elevated road proposed for southern corridor
Alongside the ongoing corridor project, the National Highways Authority of India (NHAI) is preparing a Detailed Project Report for another important infrastructure initiative. The proposed elevated road will connect Kalambakkam near Chengalpattu with Mahindra City.
Estimated to cost around Rs 3,186 crore, the project aims to strengthen road connectivity in Chennai’s rapidly expanding southern region, where residential, industrial and commercial development has increased transportation demand in recent years.
Authorities are also examining ways to integrate the proposed elevated road with the ongoing expansion of the Chennai Metro Rail network. Such integration is expected to create improved multimodal connectivity, allowing commuters to switch more efficiently between road and metro transport.
Highway expansion and safety upgrades planned
The NHAI is also moving ahead with plans to widen the Chengalpattu-Tindivanam National Highway into a six-lane carriageway during the current financial year. The expansion project, estimated at Rs 398 crore, is intended to accommodate rising passenger and freight traffic while improving travel efficiency along this busy highway section.
In a separate road safety initiative, work is set to begin on improving accident-prone locations along the Tindivanam-Puducherry National Highway. The Rs 147-crore project will focus on seven identified black spots where engineering improvements and upgraded road infrastructure will be introduced to enhance safety for motorists.
Toll plaza policy remains unchanged
Officials also reiterated the existing policy regarding toll plaza placement on national highways. Under standard guidelines, toll plazas are generally located at intervals of around 60 kilometres. However, authorities noted that certain highway stretches may have fewer toll plazas within that distance to reduce the financial burden on road users while maintaining efficient operation and upkeep of the national highway network.
