[3] Completion of D3 in the Central Bohemian Region is planned by 2028, however its designed course through the Lower Sázava landscape is still objected and opposed by environmental and citizens associations.

The opening ceremonies of these two sections cost the Regional Directorate of Transport a total of CZK 420,000, for which it was criticised.

In June 2024, ŘSD managed to start the completion of about 400 metres of the right-hand lane of the D3 motorway on the Tábor bypass, after obtaining a valid construction permit.

On 21 December 2024, České Budějovice bypass (from Úsilný to Kaplice-Nádraží) was put into operation, marking the first time 111 kilometres (69 mi) of motorway opened in the Czech Republic in one calendar year.

The 3.5 kilometres (2.2 mi) section between Nažidla and the state border with Austria is in construction since January 2024, and planned for opening in 2026.

the previous sections are in preparation, without an approved planning decision yet Content in this edit is translated from the existing Czech Wikipedia article at cs:Dálnice D3; see its history for attribution.
