The Nichol's Gap Road was a central Pennsylvania highway established in the 18th century near Maryland, extending westward from the Black's Gap Road "just west of Little Conewago Creek"[1] at the Crofs Keys stand of James Black.
[2] The road went past both the Rock Creek Church[3] and the 1761 Samuel Gettys tavern where Gettysburg would be surveyed in 1786.
In addition to excavations for parts of the Tapeworm bed, the Commonwealth built a single-arch stone roadway bridge over Toms Creek for the Nichol's Gap Road.
(The 1888-9 Western Extension by the Baltimore and Harrisburg Railway still uses a stone arch bridge over the road at Iron Springs, Pennsylvania.)
In 1913, the original Lincoln Highway was designated on the portion of the route between Gettysburg and Cross Keys, and in 1920 the Commonwealth offered the toll house west of Fairfield for sale.
