The plank road was acquired by the state of New York in the early 20th century following the completion of four projects to improve different parts of the road. In Kingsbury, the highway was rebuilt as part of two contracts, the earliest of which was awarded on February 5, 1908 to Linehan and Burman, a local contracting firm. The portion reconstructed under this project was added to the state highway system on November 18 of that year as State Highway 720 (SH 720). A segment excluded from the original contract was improved under a second contract let on June 15, 1911, and accepted into the state highway system on September 4, 1912, as SH 720A.
