New York State Department of Transportation’s Annsville Circle Flood Mitigation Project improved safety and resilience by reducing flooding along a key Hudson Valley highway in Cortlandt, NY. It uses advanced materials and technology to keep traffic moving, better protect infrastructure, and create new multimodal opportunities for recreational users. Prior to construction, Annsville Circle would flood between 10 to 15 times per year, usually during periods of high tides. The circle would also close two to three times annually due to flooding, significantly disrupting traffic along this major north/south artery on the east side of the river. This $25 million project used innovative Lightweight Foamed Glass Aggregate – a lightweight fill material manufactured from 100 percent post-consumer recycled glass – and geosynthetic reinforced soil technology to elevate the highway at the Annsville Circle by four feet and lift other sections of the road in the vicinity of the circle by as much as seven feet. The project also improved visibility by installing LED streetlights and added new pedestrian sidewalks and a shared-use path connecting users to Annsville Preserve Park and the Hudson River. The NYSDOT said the Infrastructure Investment and Jobs Act provided $11.5 million to help fund this project; funding that accounted for just under half of the total project cost. In the end, elevating this stretch of road protects residents of the lower Hudson Valley and helps them get to work, school, and home safely. This project makes Cortlandt more resilient to severe weather and to the effects of climate change.
