The D3 motorway (Czech: Dálnice D3) is a highway in the Czech Republic. Currently only the middle segment of the route is in operation; when complete, it will run from Prague via Tábor and České Budějovice to the Czech-Austrian border at Dolní Dvořiště. It is part of the European route E55. The D3 motorway in the South Bohemian Region towards the Austrian border should be completed by 2025. 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.
