By early September 2026, the Czech Republic’s infrastructure modernization continues to drive significant transport disruptions and milestones. On the D35 motorway, a new 6.2-kilometer section connecting Ostrov and Vysoké Mýto has opened without highway tolls, though the Homole tunnel remains closed until summer 2027. While work continues on the stretch between Džbánov and Litomyšl, the third stage of the D35 feeder road is estimated to cost 2.45 billion CZK. Preparations for the D35 section through the Bohemian Paradise region have been reset, potentially delaying construction until at least 2033.

In South Bohemia, the Road and Motorway Directorate (ŘSD) has opened a 3.2-kilometer feeder road connecting the D3 motorway to Český Krumlov. Additionally, an 8.5-kilometer bypass for Dasné and Češnovic on the route from České Budějovice to Písek is scheduled to open on October 3. Initially, this bypass will operate with one lane in each direction at a 70 km/h speed limit, with full completion expected in approximately one year.

New developments include the expansion of the electronic tolling system, which as of September 1, covers approximately 17.2 kilometers of newly constructed sections on the D3, D35, and D49 motorways. On the D7 motorway, a three-kilometer portion near Knovíz has opened in a 1+1 configuration, with the full section expected in 2027. 

Regional disruptions include the complete closure of road II/224 between Kadaň and Podbořany from September 7 to October 18 for surface remediation. In Prague, tram network works continue near Olšanské náměstí through October 10, while a new school street zone on Klimentská street has been established as a one-year trial to increase safety near Jiří Gutha-Jarkovský Primary School.
