As reported on the website of the Wrocław branch of the General Directorate for National Roads and Motorways:
We inform you that from Tuesday, 14 September comprehensive works related to replacing expansion-joint seals, eliminating cracks and repairing spalled areas will begin on the A4 motorway, on the section from the Budziszów interchange to the Pietrzykowice interchange. Every day, traffic management will be introduced cyclically, closing one lane (the right or left) over a 500-metre section.
The road manager specifies:
Work on the southbound carriageway will be carried out from Monday to Wednesday, while work on the northbound carriageway will take place from Thursday to Saturday. The project may cause disruptions, which will be monitored on an ongoing basis. If severe congestion occurs during peak hours, breaks will be introduced to improve traffic flow, and work will resume once the congestion has eased.
The works are scheduled to continue until 22 October 2021. GDDKiA:
Drivers are asked to exercise caution!
