Climate change behind repeated flooding of route into Hudson

Jan 25, 2024 12:59 am

Roger Hannigan Gilson reports in the Times Union that one of the main routes into the City of Hudson floods repeatedly now, which is only getting worse with climate change. Route 9G/23B brings drivers from the Rip Van Winkle Bridge through wetlands that abut the Hudson River just before entering the city of Hudson. And the South Bay often floods the road during rainstorms. The Hudson River is tidal, so the flooding ebbs and flows. Greenport Highway Superintendent John Mausolf said, “If we get a heavy rain, a lot of times during low tide we’re fine.... There may be an inch or two (of water on the road), but when the high tide hits, it compounds the problem.” New York Department of Transportation workers often must redirect traffic from the Rip Van Winkle Bridge to an alternate route further west, where traffic can access Hudson via Route 9 because of the flooding. Recently Route 9G flooded during a Dec. 18 storm and during a rainstorm Jan. 10. The story says, "By 2080, the Hudson could rise 2 to 4 feet, according to the DEC, and as much as 6 feet by the end of the century. At even 3 feet of river rise, the Hudson could inundate the road on a daily basis even when it is not at high tide, according to the National Oceanic and Atmospheric Administration’s Sea Level Rise Mapper."
