A new lighthouse was built in 1914, this time as a caisson lighthouse. Unlike the previous two, the new lighthouse remains standing today. The only repairs that have been done to it since its construction were to fix erosion damage. It was automated in 1964.
As part of the National Historic Lighthouse Preservation Act, it was auctioned off to Peter Jurewicz for $65,000. After restoration and renovations, the Thimble Shoal Lighthouse remains an active beacon. It was added to the National Register of Historic Places in 2002.
