170 Meters of Progress Made in One Month on the Steel Deck Installation

Oct 01, 2026

Construction of the steel deck for the Third Bridge Project is continuing. Installation and welding of 41 of the 59 steel decks have been completed, and 415 meters remain until the two sides are joined.

This month, 170 meters of progress was made in the steel deck installation work on the 3rd Bosphorus Bridge, a project implemented by ICA. Assembly and welding operations have been completed on 41 of the 59 steel deck sections, the heaviest of which weighs 923 metric tons. With the installation of these 41 steel deck sections, only 415 meters remain until the two sides of the bridge are joined.

The 3rd Bridge Steel Deck Coordinator stated that, on average, one steel deck panel is installed on each side every 9 days. “Since the steel deck installation began at the end of March, we have nearly reached the final 400 meters. At least three steel deck panels were installed and welded on each side every month. For the continuation of the D00 transition segment on the European and Asian sides, 20 steel deck panels were installed on the European side and 19 on the Asian side. With the installation of the final steel deck panel, the distance between the two continents has been reduced to 415 meters,” he said.

Previously, during the steel deck panel installation process, the panels were first lifted onto land and then raised to bridge level using cranes. After the removal of the deck sections that had been placed on land, the operation evolved into one where we lift steel deck sections directly from the sea using cranes.

A total of 1,500 people are working around the clock at three factory sites to manufacture the 59 steel deck sections. Steel sheets imported from South Korea are prepared for panel production at the manufacturing facility in Gebze, Izmit, and then sent to the factory in Tuzla, Istanbul, for panel production. After the panels are produced, they are shipped to Altınova, Yalova, to be assembled into steel deck sections.
