The Bureau replaces the original lighthouse with a combination lighthouse/fog signal building made of reinforced concrete. The structure was completed in the Moderne styles marking the transition between the wooden hexagonal and octagonal structures of the early 1900s and the tall rectangular Art Deco designs of the 1930s.
Further enhancements include the construction of two keepers quarters, a boat house, an oil house, and a fully equipped landing wharf with a derrick. All but one of the keepers quarters remain on the site today.
