Jedná se přitom o stavebně mimořádně náročné úseky – jen mezi Kaplicí-nádraží a Nažidly, v délce 12 kilometrů, vzniká celkem 13 mostů. Stavbaři se sice potýkají s komplikacemi, byl jsem však ujištěn, že všichni dělají maximum pro to, abychom letos zprovoznili prvních 9 kilometrů nové dálnice a zbývající část dokončili v polovině příštího roku. Tím bude jihočeská D3 kompletně dostavěna, zvýší se bezpečnost provozu a tranzitní doprava se přesune z dosavadní přetížené silnice I. třídy,“ uvedl ministr dopravy Ivan Bednárik. Na úseku Kaplice-nádraží – Nažidla o délce 12 kilometrů, jehož projektová příprava probíhala od roku 2008 a výstavba byla zahájena v červnu 2024, aktuálně probíhají intenzivní práce jak na mostních objektech, tak na samotné trase dálnice. Vzniká zde celkem 13 mostů o souhrnné délce přes 2,6 kilometru, včetně dvou významných estakád Zdíky a Suchdol. První etapa tohoto úseku, vedoucí od Kaplice-nádraží do Kaplice, má být uvedena do provozu již letos, což představuje urychlení oproti původnímu harmonogramu. Druhá etapa směrem na Nažidla bude dokončena v roce 2027. Na navazujícím úseku Nažidla – Dolní Dvořiště o délce 3,2 kilometru se stavba nachází rovněž ve velmi pokročilé fázi. Zprovoznění je plánováno na letošní léto. Součástí stavby jsou mimo jiné dva mostní objekty a mimoúrovňová křižovatka, která zajistí napojení na Dolní Dvořiště a Vyšší Brod. Na českou dálnici D3 by měla na rakouské straně navázat rychlostní silnice S10, která je aktuálně ve výstavbě. V realizaci je úsek Freistadt-Nord – Rainbach s předpokládaným zprovozněním v průběhu příštího roku, navazující část Rainbach – státní hranice je ve fázi přípravy a pokud vše půjde podle předpokladů, dojde k jejímu zprovoznění přibližně v roce 2032. „Minulý pátek jsem ve Vídni jednal s rakouským ministrem pro inovace, mobilitu a infrastrukturu Peterem Hankem. Ujistil mě, že silnice S10 je pro Rakousko prioritním projektem a že si uvědomují, že dokončení naší D3 bez kvalitního napojení na jejich síť není ideální. Věřím proto, že plnohodnotné propojení D3 a S10 bude vybudováno co nejdříve,“ uzavírá ministr Bednárik.
