Completion of works relating to the resurfacing of the carriageway

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 3 November 2026, work will be carried out only at the Balice toll plaza and on the repair of bridge structures, with no significant impact on the motorway’s capacity. In addition, short-term finishing works, tests and measurements of a local nature will be carried out.

ROAD SURFACE REPLACEMENT
On the section between the Byczyna junction and the Mysłowice toll plaza, temporary road signs are being removed on the carriageway towards Katowice, and during night-time hours, the carriageway towards Katowice is reduced to a single lane. Normal traffic towards Katowice is scheduled to be fully restored on 30 October 2026.

No maintenance work will be carried out at the Balice toll plaza between 29 October and 3 November 2026.
From 3 November to 16 November, individual toll lanes in both directions will be closed successively due to the works.

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.
