The Bolesławiec–Stare Jaroszowice road is another investment project completed by Bolesławiec County in 2020. The reconstruction of the 3,780-metre-long roadway involved laying a new bituminous surface together with the installation of a reinforcing mesh.
As part of the reconstruction, bushes were cut down and the verges were cleared and reinforced. Earthworks were also carried out to restore ditches and rebuild culverts and access roads, and new vertical road signs were installed.
