The U.S. Army Corps of Engineers presented a $35 million plan to replace the two bridges along Route 1 into Port Chester, N.Y., to improve water flow in the Byram River. The area near the river was hit hard by flooding, particularly in Pemberwick, after Hurricane Ida this past summer. The cost of the project covers $5 million for continued design work and $30 million for the bridge replacement. Greenwich and the federal government would pay about half the cost of each bridge replacement, although since the bridge goes into Port Chester, the town may end up splitting its end of the bill with New York, officials said. Nothing has been finalized, but officials were optimistic about the project.
