As reported on the Bolesławiec police website:
Please be advised that, as of June 25, 2018, traffic arrangements will change in connection with the commencement of works entitled “Expansion of the roundabout in Kruszyn along national road no. 94 in order to connect provincial road no. 297 according to its new route, as part of the project: ‘Connecting the cities of Lower Silesia: construction of Bolesławiec’s south-eastern bypass.’”
The road will be closed until further notice on the final section of Tysiąclecia Avenue in Bolesławiec—right next to Solidarności Roundabout in Kruszyn. This applies both to entering the roundabout from Tysiąclecia Avenue and leaving the roundabout onto that street.
A detour will be available via national road 94, toward the roundabout on Kościuszki Street in Bolesławiec. Details are shown in the graphics below:
The police add: “We appeal to both drivers and pedestrians to exercise caution and patience.”
