Bulgaria → Romania crosses the Danube at Ruse–Giurgiu, Vidin–Calafat or via the Oryahovo–Bechet ferry. Since 1 January 2025 both are Schengen for land borders — no permanent controls. The Danube bridges are tolled (~BGN 4 / EUR 2 for cars). Long-haul transit traffic from Greece and Turkey to central Europe routes through here.
