In late July 2026 the Czech Roads and Motorways Authority announced that the final 3.2‑km stretch of the D3 motorway linking Nažidla to the Austrian border would open in November, with the remaining southern section expected next year and the central 60‑km segment targeted for completion by 2032. A few days later the authority opened a 3.5‑km segment at the border, financed mainly by EU funds, featuring bridges, noise barriers and water‑treatment measures. The opening is expected to divert about 20,000 vehicles daily away from the village of Dolní Dvořiště, reducing noise and emissions, while work continues on the remaining Czech section and a short gap on the Austrian side.
