Two landmarks on the Outer Banks will be going dark for needed repairs.
The Bodie Island Lighthouse and the Ocracoke Lighthouse will shut down their lights next Monday.
The National Park Service says the Bodie light will shut down for at least 18 months. Repairs include removing 344 glass prisms for cleaning, restoring the panels that hold the prisms and the pedestal that supports the lens, strengthening the lighthouses spiral staircases, and installing a fire detection and suppression system.
The work on Ocracoke is expected to take about four months. The repairs will include renovation of metal work on the interior and exterior, correcting the lightning protection measures and painting both the inside and outside of the lighthouse.
The Bodie Island Lighthouse still uses its 1871 Fresnel lens and is on the National Register of Historic Places.
