Work is scheduled to begin on July 27, 2026, and conclude by September 14, 2026, with operations running seven days a week for twelve hours each day. The project site is located at latitude 40° 38' 44.2428\" N and longitude 74° 10' 46.2036\" W.\nOn-site equipment will include a dredge, a tending tug, hopper scows, a towing tug for loaded scows, and a crew boat. For safety and coordination, vessels involved in the project will operate on radio channel 78 and monitor channels 13 and 14. To minimize impacts on navigation, the project will follow a “move on demand” approach, with a tending tug available to relocate the dredge and scows as needed to avoid impeding other vessels.
