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