Benjamin Franklin Bridge Maintenance, Reduced Vertical Clearance

Mariners are advised that an engineering firm, on behalf of the Delaware River Port Authority, will be removing cables from the underside of the I-676 (Benjamin Franklin) Bridge, at mile 100.2, across the Delaware River, in Philadelphia, PA. Work is scheduled from 7:30 a.m. to 3:30 p.m. Monday through Saturday from February 24, 2025, through March 7, 2025. To facilitate this work the movable platform under the bridge will be utilized. The platform will reduce the vertical clearances of the bridge under the middle 800 feet of the span to approximately 121 feet and 114 feet under the rest of the river channel span. Vessels able to pass through the bridge with the reduced vertical clearance may do so at any time. Vessels that are not able to pass through the bridge with the reduced vertical clearance are required to give a minimum of 4 hours advanced notice to the Coast Guard via phone at (267) 515-7294. Outside of the stated work hours the vertical clearances will return to normal, and vessels may transit through the bridge without notice. Mariners are advised to transit the area with caution.
