It is located at the intersection of Wardite Street and Frankfort Avenue along the border of the Northwood and North Holland neighborhoods in northern Algonquin, Liberty City. The Frankfort Low underground station is located under this stop. Frankfort High is the terminus of the K/C Algonquin Inner Line and the beginning of the E/B Bohan Line. It is the only overground station in Algonquin and the only overground station on the network to contain ticket barriers (though these are non-functioning and the protagonist can simply walk through them).
The station is based on the 125th Street station at the border between Morningside Heights and Harlem, in northern Manhattan, New York City. The station's steel arch model has also been incorporated into the Huntington Street station.
