Our story starts with milestones such as the İstinye Highway Bridge, the Babaeski-Kuleli Road, the Unkapanı Flyover, the Ortaköy Viaducts, and the approach roads to the Bosphorus Bridge (today known as the 15 July Martyrs Bridge). Each one left its mark on the country’s infrastructure map.
As years passed, our ambition grew. We took on the Gerede-Ankara and Ankara Peripheral Motorways, and gave a new life to İstanbul’s Haliç Bridge through a complete renovation and expansion.
Our expertise in large-scale infrastructure became a defining strength. With the support of our subsidiaries Çimtaş and Kasktaş, we helped bring to life two of Türkiye’s most iconic suspension bridges – the Osmangazi Bridge and the 1915 Çanakkale Bridge – connecting not just cities, but people and opportunities.
But our journey didn’t stop at Türkiye’s borders.
Since the 1990s, in partnership with Bechtel, we have delivered transformative motorway projects in Albania, Romania, Croatia, and Kosovo. Today, we continue this legacy with major projects in Serbia and North Macedonia.
Each project is more than just a road or a bridge – it’s a pathway for trade, a link between cultures, and a foundation for sustainable growth.
Together, they strengthen the bonds between the Balkans and the rest of Europe, paving the way for a connected, prosperous future.
