Traffic disruptions in Turkey have been driven by both emergency incidents and scheduled infrastructure projects. In mid-September, a truck fire near the Bahçeşehir area in Istanbul forced the closure of the TEM Highway toward Edirne, requiring emergency services to manage smoke and potential explosion risks.

By late September, disruptions transitioned into widespread delays caused by ongoing road maintenance and renewal projects. In Istanbul, work on the TEM Motorway viaducts, specifically the Molla Gürani Viaduct, has significantly increased travel times on the Fatih Sultan Mehmet Bridge and surrounding roads. 

Nationwide, the General Directorate of Highways reported various active sites, including closures on the Ankara-Konya road, superstructure renewals on the Niğde-Pozantı and Sakarya-Bilecik routes, and electrical maintenance in tunnels along the Giresun-Keşap-Dereli route.
