Minor delays expected as sandbag work progresses along N.C. Highway 12 on northern Ocracoke

Work is underway on a sandbag replacement project along a vulnerable stretch of N.C. Highway 12 on northern Ocracoke Island, and motorists should expect minor delays due to ongoing single-lane traffic controlled by a temporary signal.

The North Carolina Department of Transportation (NCDOT) is replacing deteriorated sandbags north of the National Park Service’s pony pens, an area that has experienced repeated ocean encroachment during storms and extreme high tides.

According to NCDOT, the sandbags are being replaced using the same configuration. The bags measure roughly 15 by 5 by 2 feet and are stacked three bags high to form a temporary protective barrier along the highway’s oceanfront edge.

The project is the latest in a series of efforts aimed at keeping Ocracoke Island’s only roadway open as erosion and overwash continue to threaten the corridor. This stretch of N.C. Highway 12 has required frequent maintenance in recent years, with crews repeatedly rebuilding dunes, installing sandbags, and repairing pavement damaged by ocean flooding.

A similar sandbag replacement project was completed in 2024, when compromised bags were removed and new barriers were installed, while dune elevations were rebuilt along the oceanfront side of the highway.

State regulators have also recently adjusted how the highway can be protected when it comes to temporary measures. In November, the North Carolina Coastal Resources Commission approved a rule change allowing NCDOT to use more durable alternative sandbag designs for safeguarding imminently threatened roadways such as N.C. Highway 12.

The work on northern Ocracoke comes as officials continue to examine longer-term challenges in the area. Studies shared during a 2025 Ocracoke community meeting described a difficult outlook, citing inlet shoaling, shoreline retreat, and rising water levels that continue to compromise ferry access. 

Winter dredging projects have been deployed to maintain navigability through the inlet, but when it comes to the highway, officials have noted that sandbag placement provides only temporary relief.

Hyde County officials have urged state leaders to pursue more lasting solutions, calling for repairs to protective infrastructure as well as a beach nourishment study for the area.

For now, however, access to the island continues to rely on interim measures such as sandbag replacement, dune rebuilding, and periodic dredging projects to keep nearby channels navigable.

Motorists traveling through the construction area are advised to slow down and be prepared for brief delays while work continues.

The project is expected to continue for the next few weeks.
