History
When Pennsylvania first legislated its routes in 1911, what is now PA 456 was not legislated as part of a route.[10] By 1930, what is now PA 456 existed as a paved connecting road.[11] PA 456 was designated in 1937 to follow its current alignment between the Maryland border and PA 16.[2][3][7] The bridge going over Little Cove Creek was built in 1937 and reconstructed in 2007.[7] The one going over Licking Creek was built in 1967.[6]
