Location: 40-45.21N 074-05.71W Bridge Name: Portal (N) Bridge Portal (N) Bridge Bridge replacement to the Portal Bridge North, across Hackensack River at mile 5.04 is in progress. The Portal North Bridge will be inoperable starting Friday October 9, 2026.and the vertical clearance will remain at 23 feet until demolition is completed. The anticipated completion of the Portal North Swing Bridge demolition is tentatively scheduled for January 29, 2027 at which time the vertical clearance will increase to 50 feet. Until that time, hours of operations are from Monday to Friday between 6:30 a.m. to midnight. There will be waterborne equipment blocking one draw of a swing bridge at a time and the other draw will be free and clear of any equipment for the passage of vessels. Mariners can contact one of the three (3) provided telephone numbers/emails or via marine radio VHF-FM CH 13/16 advising of travel through the channel (including possible return trips): 1. Martir Ortez – Main Span Project Manager – (562) 307- 4916, [email protected] 2.Ryan Hirce – General Superintendent – (929) 639- 0039, [email protected] 3. Jim Hummel – Main Span Area Lead - (917) 417- 4885, [email protected] Skanska Traylor PNB JV has been awarded the construction of the New Portal North Bridge Project (NJT Contract No. 20-083X, WBS No. GC.02) with a Notice to Proceed of April 7, 2022. Specific to the Hackensack River work, mile 5.0, the project consists of constructing two bridge piers, demolition of the existing center pier north fender, erecting three tied-arch spans of approximately 400 LF (1,200 LF overall), and demolition of the existing bridge once railroad traffic is switched to the new bridge. The current status of the channels: East Channel – Open West Channel – Closed. The Coast Guard is modifying the operating schedule that governs the Amtrak Portal Bridge across the Hackensack River, mile 5.0, at Little Snake Hill, New Jersey. This action is necessary to facilitate the construction of the new replacement Portal Bridge North, as designed by Amtrak as the owner of the bridge, adjacent to the current Amtrak Portal Bridge. This final rulemaking limits the extent of the opening of the Amtrak Portal Bridge in the horizontal position to prevent the swing span from striking the new Portal Bridge North during construction as follows: The draw shall only open to 55 feet horizontal clearance in the east channel and the west channel will be closed to all navigation while the draw is open. Whenever any bridge opening is needed, contact one of the three (3) provided telephone numbers/emails above with 24-hour advance notice to allow the removal of any waterborne equipment from the East Channel that restricts the horizontal clearance to less than 55 feet. The draw need not open for the passage of vessel traffic from 5 a.m. to 10 a.m. and from 3 p.m. to 8 p.m. Additional bridge openings shall be provided for tide restricted commercial vessels between 7 a.m. and 8 a.m. and between 5 p.m. and 6 p.m., if at least a two-hour advance notice is given by calling the number posted at the bridge. At all other times the bridge shall open on signal if at least a 2-hour advance notice is given. Please be advised that the existing Portal Bridge east channel horizontal clearance (temporary fender) will be maintained at approx. 55ft and west channel horizontal clearance at 91ft until it’s demolished, both with a closed swing bridge vertical clearance of 23ft. With a swing bridge opening, the vertical clearance increases to 50ft with the existing Portal Bridge east channel horizontal clearance (temporary fender) being maintained at approx. 55ft and west channel being closed. Mariners are advised to exercise caution when transiting the area. This project will be completed by October 22, 2027.

General / LAA / RNA / Temporary Regulated Navigation Zone
The Coast Guard is establishing a temporary regulated navigation area (RNA) and a safety zone on the Hampton River at the inlet to Hampton Harbor, Hampton, NH, in response to hazardous conditions created by construction activities for the Neil R. Underwood Seabrook-Hampton Harbor Bridge replacement project. This rule is necessary to provide for the safety of life in the areas undergoing demolition and construction. The RNA will be enforced from July 1, 2025, through December 31, 2030, and will establish the following operating restrictions on vessels: Nothing in this regulation relieves any vessel, owner, operator, charterer, master, or person directing the movement of a vessel, from the consequences of any neglect to comply with this part or any other applicable law or regulation (i.e. the International Regulations for Prevention of Collisions at Sea, 1972 (72 COLREGS) or 33 CFR part 84—Subchapter E, Inland Navigation Rules) or of the neglect of any precaution which may be required by the ordinary practice of seamen, or by the special circumstances of the case. Entry and movement within the RNA is subject to a “Slow-No Wake” speed limit. All vessels may not produce a wake and may not attain speeds greater than five (5) knots unless a higher minimum speed is necessary to maintain bare steerageway. Any vessel transiting through the RNA must make a direct passage. No vessel may stop, fish, moor, anchor, or loiter within the RNA at any time. Vessels may not pass (overtake) another vessel within the RNA. Only one vessel is permitted to pass through the center span navigational channel at any given time. Except when transiting through the center span navigation channel, no vessel or craft may operate within 20 feet of the bridge(s). The operator of any vessel transiting in the RNA must comply with all lawful directions given to them by the COTP or the COTP's on-scene representative. viii) One-way traffic will flow northbound between the eastern side of the shallow waters and the Seabrook-Hampton Harbor Bridge. The northern side of the shallow area will accommodate one-way traffic moving west. The Safety Zone, includes all navigable waters within a 50-yard radius of the center point of the bridge, will be effective from July 1, 2025, through Decmember 31, 2030, but will only be enforced during active construction within the main span navigational channel or other instances which may cause a hazard to navigation as determined by the COTP. The COTP will make notification of the exact dates and times in advance of each closure period of the safety zone to the local maritime community through the Local Notice to Mariners and will issue a Broadcast Notice to Mariners via marine channel 16 (VHF-FM) as soon as practicable in response to an emergency. The complete rulemaking is available under Federal Register docket number USCG-2025-0389 and can be accessed through the federal portal at https://www.regulations.gov/document/USCG-2025-0389-0001 We invite your comments on this rulemaking.

Location: 39-44.87N 072-25.11W The Wildlife Conservation Society submitted a Notice to Mariners regarding planned acoustic monitoring work near the Hudson Canyon. The project involves deploying four small, fully submerged acoustic recorders at four sites near the northern end of Hudson Canyon to detect vocalizing cetacean species and characterize the ambient underwater noise environment. The equipment consists of compact acoustic recording units suspended approximately two meters above the seafloor between an anchor and a small sub-surface float. The design has no surface expression and uses an acoustic release system intended to leave no equipment or mooring on the seafloor after recovery. The listed monitoring sites are located at approximately 39°44'52.02" N, 072°25'6.72" W; 39°37'26.33" N, 072°28'26.67" W; 39°36'47.57" N, 072°17'9.68" W; and 39°28'44.31" N, 072°32'56.1" W. Initial deployment is planned for August 26, 2026, with retrieval and redeployment anticipated in October or November. Work will occur during daylight hours, generally between 7:00 a.m. and 7:00 p.m. Operations will use a small research vessel, approximately 6 to 10 meters in length, along with acoustic receivers, anchors, rope, sub-surface buoys, and related deployment equipment.

Location: 39-37.44N 072-28.44W The Wildlife Conservation Society submitted a Notice to Mariners regarding planned acoustic monitoring work near the Hudson Canyon. The project involves deploying four small, fully submerged acoustic recorders at four sites near the northern end of Hudson Canyon to detect vocalizing cetacean species and characterize the ambient underwater noise environment. The equipment consists of compact acoustic recording units suspended approximately two meters above the seafloor between an anchor and a small sub-surface float. The design has no surface expression and uses an acoustic release system intended to leave no equipment or mooring on the seafloor after recovery. The listed monitoring sites are located at approximately 39°44'52.02" N, 072°25'6.72" W; 39°37'26.33" N, 072°28'26.67" W; 39°36'47.57" N, 072°17'9.68" W; and 39°28'44.31" N, 072°32'56.1" W. Initial deployment is planned for August 26, 2026, with retrieval and redeployment anticipated in October or November. Work will occur during daylight hours, generally between 7:00 a.m. and 7:00 p.m. Operations will use a small research vessel, approximately 6 to 10 meters in length, along with acoustic receivers, anchors, rope, sub-surface buoys, and related deployment equipment. The recorders and floats will be placed approximately 80 meters below the surface, with no surface equipment, which is intended to avoid interference with vessel traffic. Marine radio channel 16 is listed for communications, and no disposal site is associated with the activity.

Claremont Terminal Channel Shoaling – The Harbor Safety, Operations and Navigation Committee of the Port of NY and NJ – Deep Draft Working Group: The need to immediately restrict the deep draft of vessels transiting Claremont Terminal Channel has come to our attention. Based on the latest available surveys conducted by the Army Corps of Engineers, November 4, 2024, shoaling has occurred in the channel. The shoaling has minimized the available depth of water to 15 feet near the centerline of the channel. Based on this data, vessels will be restricted to a draft of 13 feet, plus the rise in tide, with a maximum draft of 18 feet. On 11/04/2024, the shoal area was bound by the following approximate coordinates: 40° 41’11”N, 074° 04’ 41”W; thence to 40° 41’ 17”N, 074° 04’ 33”W; thence to 40° 40’ 14”N, 074° 03’ 06”W; thence to 40° 40’ 10”N, 074° 03’ 13”W.
