INTERNATIONAL PROJECTS

The bridge crossing the Jamuna River aims to enhance connectivity between the capital Dhaka and the northern and northwestern regions of Bangladesh. Initially named the Bangabandhu Sheikh Mujib Railway Bridge, it was renamed the Jamuna Railway Bridge in December 2024. The bridge is 4.8 km long, consisting of 50 piers and 49 spans. It is designed with dual-gauge tracks and two railway lanes, allowing the simultaneous operation of two trains. IIA Company fabricated the steel girders and other components for the project.

The Guacirope Bridge was constructed to replace the severely deteriorated previous bridge. It is located in the city of Nacaome, Valle Province, Honduras. The bridge is 160.6 meters long and 13.8 meters wide, with two traffic lanes and sidewalks. The main span is 117.3 meters long and features an arch structure. IIA Company fabricated the steel arch for this bridge.

This is the longest sea bridge in India and the 12th longest in the world. The bridge is 21.8 km long, with 16.5 km over the sea and 5.3 km on land. Approximately 120,000 tons of steel were used—equivalent to 17 Eiffel Towers. The six-lane bridge was constructed using advanced technologies, most notably Orthotropic Steel Deck (OSD) box girders for its long-span sea sections—a cutting-edge technology applied for the first time in India. The longest span reaches 180 meters and weighs about 2,600 tons. Over 97% of the components were precast and assembled using floating cranes, accelerating construction while minimizing environmental impact. The entire structure is designed to be earthquake-resistant and is integrated with an Advanced Traffic Management System (ATMS) to ensure operational safety and efficiency. To withstand the harsh marine environment, the bridge is coated with a special anti-corrosion paint, enhancing its durability and lifespan. IIA Company fabricated the OSD for this bridge

The project was implemented to enhance transport capacity on National Highway No. 1, the key arterial route connecting the capital Dhaka with the port city of Chattogram. Faced with growing traffic congestion, the Government of Bangladesh partnered with leading Japanese construction companies to build new bridges parallel to the existing ones and rehabilitate the current structures. The second bridges were constructed alongside the original ones using continuous narrow steel box girder technology and steel pipe well foundations, requiring advanced engineering expertise. IIA Company carried out the fabrication of steel girders and steel–concrete composite deck slabs for the bridges in this project.

The Paso Real Bridge is located in Matagalpa, Nicaragua, crossing the Matagalpa River. The bridge is approximately 170 meters long and 9 meters wide, consisting of two main spans of 85 meters each. It utilizes continuous steel truss girders with a reinforced concrete deck. The new bridge was designed to support loads of up to 41 tons, enabling safer and more efficient travel for heavy vehicles compared to the previous temporary bridge, which could only handle up to 14 tons. IIA Company carried out the fabrication and transportation of the steel truss bridge for this project.
