The Dredge Liberty Island is returning to Nags Head after repairs in Norfolk. Beach nourishment construction will continue to progress north to tie into the already completed beach near Milepost 14.
After the tie-in is completed, construction will progress south about 5,000 feet.
Hopper dredges use suction pipes to fill their "bellies" or hoppers with sand from an offshore area. The dredges then travel to a submerged offshore pipe and pump the sand from the hopper into the pipe and onto the pre-construction dry beach.
A secondary pipe transports the sand in one direction (either north or south) and then in the other direction, completing approximately one to two mile-long sections as additional lengths of pipe are added. Bulldozers shape the new sand to meet project design specifications.
As construction progresses, the pipes are broken down and moved further along the beach until the sections of beach are completed. The closed construction area is then re-opened.
The Forrest Street public beach access near Milepost 15.5 remains closed to parking, but pedestrians may still use the access.
