Less and less. The NIK Supreme Audit Office has just examined the state of Polish roads. 38% are still in bad condition and require repair. That means that 62% are in good or very good condition.

NIK added that with the current pace of repair, we will achieve 100% in 22 years.
Of course, let`s not forget the EU has contributed its funds to many roads in Poland.
