Expansion Joint Installation Completed

Oct 01, 2026

Expansion joints—the largest of their kind in the world—which were specially manufactured in Germany, were installed on the 3rd Bosphorus Bridge.

As part of the 3rd Bosphorus Bridge and Northern Marmara Highway Project implemented by ICA, final work is underway on the 3rd Bridge following the installation of 59 steel deck panels and the tensioning of the main cable and inclined suspension cables. Finally, the expansion joints were installed as part of the project. These expansion joints, specially manufactured in Germany, are the largest of their kind in the world.

The 3rd Bridge Site Manager stated, “Although bridges may appear to be static structures, they are actually in constant motion due to variable factors such as environmental, structural, and traffic loads. The expansion joint provides the necessary movement range for the bridge deck to accommodate the displacements (expansion and contraction) caused by these factors. Made of high-quality steel, these expansion joints will maintain their structural integrity for many years, even under heavy traffic loads,” he said.

With the installation of the expansion joints, the 3rd Bosphorus Bridge and the Northern Marmara Highway have been connected.
