Poland will begin a major reconstruction of the A2 highway between Łódź and Warsaw on November 4.
The 92-kilometer stretch will be divided into four sections, with work starting on all of them in November under contractors Strabag and Budimex. The first phase involves setting up a temporary traffic system, with construction machinery entering the site later in the month. The project aims to add an extra lane on 89 of the 92 kilometers, expanding capacity to three lanes in each direction between Stryków and Grodzisk Mazowiecki, and four lanes from Pruszków toward Warsaw.
To minimize disruptions, work will proceed in alternating sections rather than simultaneously across the entire route. Speed limits will be reduced to 70 km/h, and average speed checks will cover the full 92 kilometers, including sections without active construction. All service areas and interchanges will remain accessible, with concrete barriers separating traffic from work zones.
The first completed sections—between Łowicz and the Łódź-Mazovia border, and from Grodzisk Mazowiecki to Konotopa—are scheduled to reopen by the end of 2027. The remaining parts will follow in early and mid-2028. The highway currently handles 50,000 to 100,000 vehicles daily, with traffic expected to rise further due to its role in accessing the planned Central Communication Port.
Strabag will manage three sections from Łowicz to Konotopa, while Budimex handles the Łódź Północ interchange and the northern stretch. The project includes deep earthworks, new pavement, and the construction of additional lanes in the median. Executives from both firms emphasized the tight timeline, with each section requiring completion within 13 to 16 months.
The modernization addresses growing congestion on one of Poland’s busiest routes, now 13 years old. Officials noted the need to balance rapid execution with minimal disruption to the 50,000–100,000 daily users, including future traffic linked to the Central Communication Port .
