A footfall of nearly 30,000 per day is expected once the skywalk becomes operational.
Delhi Deputy Chief Minister Manish Sisodia on Saturday said about 75 per cent work of skywalk at the ITO area has been completed and it is likely to be inaugurated by September-end or early October.
Mr Sisodia, who along with PWD Minister Satyendar Jain inspected the site of the project said this would be a "beautiful infrastructure" in the city.
The over 600-metre-long skywalk will connect Sikandra Road, Mathura Road, Tilak Marg and Bahadurshah Zafar Marg with Pragati Maidan and ITO Metro stations and the Supreme Court.
"The work began in April, about 75 per cent work is over, and by September end or first week of October, it should be ready. This along with the Signature Bridge slated to open in October, would be two new gifts to the people of Delhi before Diwali," Mr Sisodia told reporters.
He said besides adding to the aesthetic look of the city, the skywalk would also prove a boon for decongesting the city.
"From metro stations in New Delhi, people would be able to go directly to nearby locations, like ITO, Tilak Marg and Supreme Court, etc, without the need to step out on to the street from the stations," he said.
Delhi's Deputy Chief Minister Manish Sisodia and PWD Minister Satyendar Jain inspected the site of the project.
Authorities are expecting a footfall of nearly 30,000 per day once the skywalk becomes operational.
The total worth of the project is about Rs 54 crore.
"The project will be completed in six months. It will have glass lifts an solar-powered utilities and CCTV cameras. It will be very user-friendly," Mr Jain said.
Mr Sisodia after visiting the site also tweeted pictures, showing the current status of the skywalk.
"Construction of Sky-Walk (Delhi's most beautiful foot-over bridge) would be complete within one month. It'll help 30,000 commuters daily to cross roads safely, above heavy traffic at Tilak marg crossing.
"Also, #SkyWalkITO is going to be a 'pride place to visit' for every Delhi citizen. Above the hustle bustle of ITO, it truly feels like walking in the sky," he said in a series of tweets.
As part of the skywalk project, a 60-metre-long foot overbridge (FOB) will also be constructed on Bahadur Shah Zafar Marg near Hans Bhawan.
Around 25 major offices are located in the ITO area, including the Delhi Police and PWD headquarters, Institute of Engineers, Income Tax office, Central Excise, DDA office, School of Planning and Architecture, Supreme Court and Pragati Maidan.
