In late July 2026, extensive repair projects triggered full and partial road closures across several Czech regions, including major works on the I/4, I/20, and numerous secondary routes. Heavy trucks and long‑distance buses were rerouted, while motorists were warned of longer travel times and advised to follow detour signs.

A week later, the Central Bohemian Road Administration began testing a new web portal that aggregates information on completed, ongoing and planned road works. The portal lists closure dates and expected restrictions months in advance, aiming to improve coordination among municipalities, investors and road managers and to reduce overlapping disruptions. Officials expect full operation by early October, with future integration for public‑transport planners.
