Works on the A4 motorway, section Katowice-Krakow - update

We would like to inform you that we have completed the final stage of modernisation works (resurfacing of the carriageway) on the A4 Katowice–Kraków motorway. From 12 November 2026, works will be carried out only at the Balice toll plaza and only on the carriageway heading towards Kraków. In addition, repairs to bridge structures are underway, with no significant impact on the motorway’s capacity, as well as short-term finishing works, tests and measurements of a local nature.

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 current 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 excellent technical condition, i.e. in a state that will not require repairs or modernisation in the years to come.

We apologise for any disruption to traffic and ask that you pay particular attention to road signs.
