Navigation on the Dnieper–Bug Canal is interrupted by weirs on the rivers Mukhavets and Bug near Brest, Belarus, the border town. That is the only place that makes impossible, for the time being, the navigation from Western Europe to Belarus and Ukraine through inland waterways. The waterways from the German-Polish border (Oder River, through the Warta, Brda and Noteć rivers, Bydgoszcz Canal, Vistula River, Narew River, Bug River) once used to link the Belarus and Ukrainian inland waterways via Mukhavets River, Dnieper–Bug Canal, Pripyat River and Dnieper River), thus connecting north-western Europe with the Black Sea.
