Modernisation works on the A4 motorway, section Katowice-Krakow

We kindly inform you that at the beginning of March, the final stage of modernisation works (replacement of the road surface) on the A4 Katowice-Kraków motorway will commence. The works will be carried out without significantly affecting the capacity of the route, with two lanes maintained in both directions.

From 28 February, work will be carried out to change the traffic organisation on the carriageway towards Kraków between the Chrzanów junction and the Rudno junction, i.e. from km 376 to km 380. There may be short-term narrowing to one lane on the above-mentioned section of the motorway. However, from 4 March:

• one lane will be open on the carriageway towards Krakow,
• two lanes will be available on the carriageway towards Katowice for travellers heading towards Katowice and one lane for travellers heading towards Krakow (both directions will be separated by a special barrier).

Completion of work on this section on both carriageways is scheduled for the May 2026.

Proper maintenance of the A4 Katowice-Kraków motorway infrastructure, including the road surface and engineering structures (such as bridges and viaducts), is required not only by applicable regulations, but also by the provisions of the Concession Agreement, which obliges the concessionaire to hand over the motorway to the public sector in 2027 in perfect technical condition, i.e. one that will not require repairs or modernisation in the coming years.

We apologise for any traffic disruptions and ask you to pay special attention to road signs.
