The Bulgarian part of the river, if we exclude the cities of Ruse, which has the only bridge connecting the two banks of the Danube, Vidin and Silistra, is perhaps the area where the municipalities are the most underdeveloped economically.
Dacă excludem oraşele Ruse, care are singurul pod care leagă cele două maluri ale Dunării, Vidin şi Silistra, partea bulgară a fluviului este probabil zona cu cele mai slab dezvoltate municipalităţi.
