Manish Chatrath, Chairman, Delhi Tourism, Sh. G.G Saxena, MD & CEO, DTTDC, Sh. Binay Bhushan, General Manager, DTTDC and Jose Kurien, Chief Engineer, DTTDC were also present during the occasion.

Delhi’s landmark project -  The first consignment of 1500 tonnes which include the pylon bases which weigh 425 tonne each, arrived at the Signature Bridge site on 10 September, 2013. The total weight of the Pylon and Deck is 14,000 tonnes. The second consignment has reached Kandla port and is on the way to Delhi. The third consignment is being shipped from Shanghai this month. The remaining two consignments will reach Delhi by end of this year.

The erection was done using a 1250 Ton capacity crane which can erect pieces up to a height of 160 m. The crane has reached the site and the pylon base will be lifted using the crane. The total weight of the steel pylon structure is 6500 Tonnes. The deck weighs 7500 Tonnes.

The central pylon is being constructed by a Shanghai-based company and the asymmetrical blocks of the pylon were brought to Gujarat via sea and transported to Delhi by road from Kandla Harbour. It has travelled a distance of 1640 KM by road from Kandla Port to Delhi.

The fabrication of the pylon was a major challenge as it comprised welding of 250 mm thick steel plates which requires highly skilled welders. The intricate and complex welding in highly confined  areas was accomplished through diligent direction and persistent efforts by expert workers. Each element of this fabricated bridge is being trial assembled in China and all aspects of geometry control were stringently checked prior to its dispatch to India. The entire process is being checked through a four tier quality checks.

The design and construction of Signature Bridge Project was entrusted to Delhi Tourism and Transportation Development Corporation (DTTDC) by Delhi Govt. The work of the two approaches has been carried out by M/s Gammon India Ltd. and the work of the main bridge is being carried out by the Joint Ventures between M/s Gammon (India),Construtora Cidade (Brazil) and Tensacciai (Italy).

Signature Bridge is designed to make a symbolic statement of emerging India. The main bridge is 675 M Long, which is asymmetrical and cable stayed. It has two approaches, the Eastern approach which is 1.8 Km long to connect Main Bridge with Marginal Bund Road at the Khajuri Khas intersection. It has a Flyover and a ground level Rotary at Khajuri Khas intersection and the Western approach has a Flyover on Outer Ring Road which covers the existing intersections at Timarpur, Nehru Vihar and Wazirabad. The main flyover on the western side has been opened to traffic. The eastern flyover is nearing completion and will be opened to traffic by early next month.

The Signature Bridge has a bow shaped steel pylon which is about 154 M heights. The main span of the bridge is 251 M long and it has dual carriageway of 14 M each (4 + 4 lanes), with 1.2m wide central verge and maintenance walkways, Cycle tracks, pedestrian subway etc.

The arrival of the first consignment on the site has paved way for the erection process to begin. Global experts have also joined this complex Endeavor and  for smooth progress.

The inclined lifts are extraordinary, and after completion visitors will be able to have a bird’s eye view of Delhi from the top of the tower. Delhi Govt. decided to make the bridge a landmark bridge and to develop the surrounding area into a Tourist Destination. The Signature Bridge will be Delhi’s future symbol and this engineering marvel will surely enhance the prestige of the city of Delhi to a world class one.
