GURGAON: NHAI has planned to develop a four-lane trumpet interchange along Dwarka Expressway to connect the upcoming Global City and Vision City projects. The underground trumpet interchange will provide signal-free connectivity between the expressway and the two upcoming residential and commercial hubs.The interchange, which will come up near the Pataudi Road junction on Dwarka Expressway (NH-248BB), has been proposed by Haryana State Industrial and Infrastructure Development Corporation (HSIIDC).HSIIDC has agreed to bear the project cost — estimated at Rs 923 crore — to facilitate access to the two upcoming residential and commercial hubs. According to a senior HSIIDC official, the interchange will play “a key role” in supporting this expansion by ensuring direct connectivity between the expressway and the upcoming developments, “while also improving access for traffic coming from Manesar and nearby industrial areas”.A senior NHAI official said, “The proposal was finalised and we are working out the modality for the execution of the project. We hope to start the work within the next three months.” The interchange is expected to take around 30 months to complete. “The layout has been designed to ensure that vehicles can enter or exit the developments without crossing high-speed expressway traffic, improving safety and maintaining uninterrupted movement on the main corridor,” the NHAI official added.
Under the plan, around 3.2km of approach roads and ramps will connect the underpass with the internal roads of Global City and Vision City. The curved loop ramp, typical of a trumpet interchange, will allow smooth turning movements, particularly for vehicles approaching from the Manesar side.NHAI officials said the interchange will allow vehicles travelling from Manesar and other parts of the city to directly enter Global City and Vision City through grade-separated ramps without interfering with through traffic on the expressway. The interchange will also create direct connectivity between Global City and Vision City, allowing vehicles to move between the two developments without entering the main carriageway of the expressway.NHAI officials said the four-lane underground vehicular underpass will be constructed using precast reinforced cement concrete (RCC) box structures. The underpass will be built using the box-pushing technique, a method that allows large concrete structures to be inserted beneath a functioning expressway with minimal disruption to surface traffic. Two precast RCC boxes — measuring 11 metres by 6 metres and about 150 metres in length each — will be pushed beneath the expressway under an eight-nine metre soil surcharge, the official explained.“The interchange will be constructed nearly 30 feet below the surface. There are pillars of the expressway and the Badshapur drain is passing below the surface. For the execution of the work, it would require deep excavation and earth-retention systems to keep the soil stable, along with continuous dewatering at the site. A thrust bed will be constructed to push large concrete boxes beneath the expressway structure with precision,” the NHAI official said, adding that the existing utilities such as sewer lines, pipelines and overhead electrical lines in the area will be protected and strengthened during the construction process.Global City is one of Haryana’s flagship urban development projects being implemented by HSIIDC. Spread across more than 1,003 acres in sectors 36, 36B, 37, and 37B along Dwarka Expressway, the project is being developed as a mixed-use urban cluster. The project is expected to include residential areas, commercial spaces and institutional facilities.The first phase of the Global City project, spread across nearly 587 acres, is targeted for completion by June 2027. Under this phase, HSIIDC is undertaking the development of internal roads, water supply, drainage, sewerage networks, electricity infrastructure, along with landscaping and plantation.Vision City, which is located across the expressway and spread over 121 acres of land in sector 88, is being conceptualised as another commercial cluster that will complement Global City.
