An extradosed bridge employs a structure that combines the main elements of both a box girder bridge and a cable-stayed bridge, officials said.
The bridge, from Malak Harhar to Stanley road (near Beli Hospital), is expected to be ready by February 2024, said officials.
“The state’s first six-lane extradosed bridge will have an overall length of 9.9 kilometers, of which 3.84 km would be the main bridge and the rest of the distance would be approach section of the bridge,” said project director Raj Kishor Singh, an Indian Engineering Services (IES) officer.
“The stretch of 3.84 km would have 67 pillars and foundation work of 17 pillars is now in process. Also, of this 3.84 km, the span of 860 meters would be extradosed bridge and the rest would be precast segmental bridge, having span of 50 meters,” he said.
“Of this, 860 meters, there would be three spans of 200 meters while two of 130 meters would be balancing spans on either side of the bridge. Besides, two spans of 50 meters would also be there on either side of the stretch,” said Singh.
“The bridge would start from the Pratapgrah road (around 500 meters from Malak Harhar trisection), gain height to over cross the existing Y-junction (going towards Lucknow) and would then cross the Ganga from Kacchar area spanning over Beli village before ending at Stanley road,” he said.
“For the commuters, wishing to move towards Lucknow, there would be a slip road using which one can turn towards Lucknow, while those going towards Pratapgrah or Faizabad would stay on the bridge and land on the existing Prayagraj-Pratapgrah highway,” said Singh who has earlier executed work on Varanasi airport link road.
To speed up the construction work, a temporary road has been constructed which would expedite the transport of men and material. “We have the challenge of expediting the construction work amid Covid-19 pandemic. The total cost of the bridge is 1948.25 crore and would be completed by February 2024,” Singh said.
