Waterway/Lock Closure Listings

Onslow Beach Swing Bridge, AICW Mile 240.7, North Carolina

The Onslow Beach Swing Bridge (Mile 240.7 on the AICW) is undergoing repairs. We've been hearing about closures but official channels like notices to mariners have not issued any information. After reaching out to Waterway Guide for assistance, their cruising editor, Bob Sherer (aka Bob423) has confirmed the following:

4/28 - 5/10 closed to marine navigation 24 hours a day, no marine traffic permitted even if the boat could get under the approximately 13 ft clearance. This will have a major impact on members heading to the Spring Rendezvous. We are looking at alternative options and will post again soon.

5/13 - 5/31 closed to marine navigation 8:00 am to noon and 1:00 pm to 5:00 pm (open to marine navigation noon to 1:00 pm) Uncertain about whether the bridge will be open before 8:00 am and after 5:00 pm. More information expected soon

6/3 - 6/7 closed to marine navigation 24 hours a day, no marine traffic permitted even if the boat could get under the approximately 13 ft clearance.

6/10 - 6/28 closed to marine navigation 8:00 am to noon and 1:00 pm to 5:00 pm (open to marine navigation noon to 1:00 pm) Uncertain about whether the bridge will be open before 8:00 am and after 5:00 pm. More information expected soon.

7/1 - 8/31 closed to marine navigation 8:00 am to noon and 1:00 pm to 5:00 pm (open to marine navigation noon to 1:00 pm) Uncertain about whether the bridge will be open before 8:00 am and after 5:00 pm. More information to come soon
