Nově vybudované stání proto nabízí výrazně vyšší kapacitu i bezpečnost a umožňuje pohodlné odbavení většího počtu plavidel. V horní vodě je široké koryto a malá rychlost proudění vody, takže vybudování pevného čekacího stání není nutné. „Máme velkou radost, že se podařilo toto důležité místo modernizovat a uvést do plného provozu. Modřanská komora patří mezi nejvytíženější na dolní Vltavě a nové čekací stání výrazně zvyšuje komfort i bezpečnost pro rekreační lodě. Reagujeme tím na dlouhodobě rostoucí zájem o plavbu a posouváme služby na odpovídající úroveň,“ říká Lubomír Fojtů, ředitel Ředitelství vodních cest ČR. „Navíc pokračujeme v systematickém doplňování čekacích stání i na dalších komorách, aby byla celá pražská i středočeská část Vltavy plně připravena na současné i budoucí potřeby vodní turistiky,“ dodává. Modřanská plavební komora je významnou součástí Vltavské vodní cesty a ve své moderní podobě slouží plavbě od roku 1984. Její vybudování umožnilo celoroční splavnost Vltavy až k Radotínu a dále směrem k Vranému nad Vltavou. Komora překonává spád 2,5 metru a dlouhodobě patří mezi klíčové body rekreační plavby v Praze. Nové čekací stání v dolní vodě vzniklo instalací šesti nových daleb, které doplnily ty stávající, čímž se jejich celkový počet zvýšil na devět. Dalby jsou vybaveny úvaznými prvky a propojeny ocelovou lávkou o délce 20 metrů. Přístup na lávku je zajištěn výhradně z lodí pomocí žebříků, což zvyšuje bezpečnost provozu a jasně vymezuje účel stání. Součástí vybavení je také komunikační zařízení pro spojení s velínem plavební komory a odpovídající plavební značení. „Realizace probíhala převážně z vody, což minimalizovalo dopad na okolí. Jsme rádi, že se podařilo stavbu dokončit bez zásadních omezení pro veřejnost a zároveň v požadované kvalitě. Výsledkem je moderní a funkční řešení, které bude dlouhodobě dobře sloužit vodákům,“ uvádí Martin Paukner, stavbyvedoucí společnosti SMP Vodohospodářské stavby a.s. Celkové stavební náklady dosáhly 21,4 milionu Kč bez DPH a projekt byl financován Státním fondem dopravní infrastruktury. Zhotovitelem byla společnost SMP Vodohospodářské stavby a.s., člen Skupiny VINCI Construction CS.
