Solomons Island Road was one of the original state roads marked for improvement to form a statewide system by the Maryland State Roads Commission in 1909. The highway was graded and surfaced as an improved dirt road from Owings south to Hunting Creek in 1910 and 1911 and from there to Prince Frederick between 1911 and 1913. Solomons Island Road from Prince Frederick south to Solomons was graded and surfaced as a dirt road in 1913 except for two segments: a wide shell road was built through Solomons and a wide gravel road was built for through Lusby. This highway was improved to a gravel road for its whole length and several dangerous curves were modified by 1919. Solomons Island Road from Lothian to Edgewater was built as a wide gravel road in 1915. The state road between Edgewater and Annapolis was also finished by 1915.
