The construction of Binh Khanh Bridge is a part of Vietnam’s Ben Luc – Long Thanh Expressway project, which will run through Ho Chi Minh City and southern Long An province and involves the construction of 58-kilometer long roads.
Being started in 2016 and scheduled to be in service within 2020, the main purpose of this project is to develop the country’s transport facilities for fast vehicles.
To ease the construction of this 58-km long expressway, the project owner Vietnam Expressway Corporation has divided the project into three phases: the western, the middle, and the eastern sections.

Smooth and Fully-threaded PT bars: post-tensioning solutions for bridges and viaducts

For the construction of the 3-kilometer long Binh Khanh Bridge, which is part of the middle section, Dextra has supplied smooth and fully-threaded post-tensioning bars have been delivered. These have been used in the main structure, the stay cable, as well as the bridge’s western and eastern approaches.

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

The 3.84-kilometer stretch would include 67 pillars and 17 pillar foundations. Also, of this 3.84 km, the span of 860 meters will be extradosed bridge, and the rest will be a precast segmental bridge with a span of 50 meters.

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

The bridge will start from the Pratapgrah road, 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. It is expected to be in operational in 2024.

The New Storstrøm Bridge is a testament to Denmark’s commitment to improving transportation infrastructure and connecting the country’s islands more efficiently. Stretching over the Storstrømmen strait, this bridge will replace the aging Storstrøm Bridge, which has served as a vital connection between the islands of Zealand and Falster since 1937.

The New Storstrøm Bridge is designed to accommodate not only vehicular traffic but also pedestrians and cyclists. Its innovative architecture and engineering are set to reduce travel time, improve safety, and provide a reliable link between these two major Danish islands.

Dextra, with its expertise in engineering construction solutions, has supplied 120,000 Rolltec couplers and headed bars for connecting pile reinforcement cages. These components are essential for the construction of the bridge’s foundation, ensuring that the piles are securely interconnected to support the immense weight and forces the bridge will experience during its lifetime.

In addition to our contribution to the bridge’s foundation, we have also supplied Unitec couplers for repair applications, connecting installed rebars with no threads. With Dextra’s contributions, this bridge will serve as a lifeline between Zealand and Falster for generations to come, connecting people, communities, and opportunities.

The Nanay Bridge is a 2.2km bridge crossing the Nanay River, north of the city of Iquitos, Peru.

The bridge will connect the district of Bellavista on the right bank of the Nanay River with the district of Santo Tomas on the left bank.

With a population of almost half a million people, Iquitos is the largest city in the world that cannot be reached by road – tucked in the Peruvian Amazonia jungle, it is currently accessible only by river and air.

Thanks to this project, the city will finally be connected with the rest of the Loreto Region.

The main structure is a cable-stayed bridge with a main span of 242m and total length of 424m. The approach structures are 1.2km long on the right bank of the river, and 320m long on the left bank of the river.

The bridge carries two lanes of traffic and two pedestrian walkways. The roadway has a total width of 12m, and each pedestrian walkway is 1.2m wide.

It uses light-weight composite steel concrete to minimize the use of concrete and to reduce loads transferred to the foundations.

For this project Dextra has supplied 100,000 Bartec couplers for rebar connection and 30,000 headed bars for shear reinforcement of the anchors.

Once completed, it will be the longest bridge in the Country.
