The six-lane extradosed bridge over the Ganga River in Prayagraj will span 9.9 kilometers, with the main bridge covering 3.84 kilometers and the approach segment covering the remaining distance.

The 3.84-kilometer stretch will include 67 pillars and 17 pillar foundations. Of this 3.84 km, an 860-meter span will be an extradosed bridge, while the rest will be a precast segmental bridge with 50-meter spans.

Dextra supplied 20,000 Sonitec tubes, an easy-to-assemble and time-saving solution used for CSL (crosshole sonic logging) testing of foundation piles to determine structural integrity. The tubes were installed in piles that were 30 to 36 meters deep with a diameter of 1.2 meters.

The bridge will start from Pratapgarh Road, gain height to cross over the existing Y-junction (leading towards Lucknow), and then cross the Ganga River from Kacchar, spanning over Beli village before ending at Stanley Road. It is expected to be operational in 2024.
