DATES: This rule is effective without notice from December 3, 2024, through 5 p.m. on May 27, 2027. For the purposes of enforcement, actual notice will be used from midnight on December 2, 2024, until December 3, 2024. This rule will only be enforced during periods when construction operations at the bridge are in progress. Comments and related material must be received by the Coast Guard on or before March 3, 2025.

All these dates are tentative and subject to change due to weather, supply chain delays, or other unforeseen circumstances. This rule remains effective through May 27, 2027, in case the project is delayed due to unforeseen circumstances. The area regulated by the safety zone will encompass the waters around the Glen Island Bridge and will cover all navigable waters, from surface to bottom, within the area formed by connecting the following latitude and longitude points in the following order: 40°53′18.58″ N 73°46′56.26″ W; thence to 40°53′22.08″ N 73°46′59.39″ W; thence north along the shore to 40°53′23.8″ N 73°46′57.51″ W; thence to 40°53′19.15″ N 73°46′52.54″ W and thence south along the shore back to the point of origin. This area is intended for the vessels and machinery being used by personnel for the Glen Island Bridge rehabilitation project. The duration of the zone is intended to ensure the safety of personnel, vessels, and these navigable waters during the bridge construction. No vessel or person will be permitted to enter the safety zone without obtaining permission from the COTP or a designated representative. The Coast Guard will make notice of the safety zone via the Local Notice to Mariners and issue a Broadcast Notice to Mariners via marine channel 16 (VHF-FM) as soon as practicable in response to an emergency or hazardous condition. |
