About the Historic National Road

The Historic National Road was the nation's first federally funded interstate highway. It opened the nation to the west and became a corridor for the movement of goods and people. Today, visitors experience a physical timeline, including classic inns, tollhouses, diners, and motels that trace 200 years of American history.

About this page's facts

The line is the Federal Highway Administration's scenic byways layer (HEPGIS, a snapshot of 2022-06-24, a US government work), cut at the state line and simplified for the map; the length is the line's. The designation is the program's own: the national tiers from FHWA's America's Byways roster, the rest from the layer's designation field. Road conditions, closures and seasonal gates change: check the agency's own page and the state's road conditions before you go.
