NCDOT Proposes Protecting Island with Steel Wall

FRIDAY, JUNE 28, 2019


The North Carolina Department of Transportation Ferry Division is looking to build a 1,000-foot-long sheet pile wall along the north tip of Ocracoke Island in order to protect the site, an area that is often hammered by extreme weather. A contract for construction on a bulkhead in the same area was awarded earlier this month.

According to The Virginian-Pilot, dunes disappear under the waves, which in turn has been known to break down pavement on N.C. 12.

Proposed plans also include the construction of groins along the north end of the island, which will be interspersed with submerged concrete structures. Collectively, this would help prevent the ferry landing area from going under water. The Outer Banks Voice notes that erosion from Pamilco Sound has damaged the ferry basin bulkhead.

“The use of both barge-mounted pile-driving equipment and land-based equipment are proposed for construction,” wrote the National Park Service.

Currently, additional, similar work is being carried out along the northern tip of the island: NCDOT recently awarded a $1.9 million contract, to Carolina Bridge, of Orangeburg, South Carolina, for the construction of a 1,000-foot-long bulkhead. The agency is also purchasing roughly $2.1 million in materials, bringing the project total to $4 million.

Work on the bulkhead, the first of these two projects, will begin the week of July 10, and is slated for completion by Dec. 20. An environmental assessment is being prepared for the steel wall, and will likely be ready for review in the fall.

NCDOT hopes to begin construction on the wall in spring 2020. The Cape Hatteras National Seashore is accepting public comment until July 22. Those interested in chiming in can do so here.
