interchange, a diamond interchange with I-81. After crossing over the freeway, a left intersection with County Route 1 provides access to Little Georgetown to the west as the pike passes through the community of Marlowe. US 11 in West Virginia ends at the southwestern bank of the Potomac River, however the roadway continues north as US 11 in Maryland. In contrast to I-81, no part of US 11 is listed on the National Highway System, a system of roads that are important to the nation's economy, defense and mobility. History The highway roughly parallels the Warrior Path, an old Indian trail which connected New York to the Carolina Piedmont via Virginia and West Virginia. A series of roads linking Virginia to Maryland through Martinsburg were present on maps as early as 1873. US 11 is one of the original six highways that were part of the U.S. Numbered Highway System in the state, the others being US 19, US 21, US 40, US 50, and US 60. The oldest bridge still in use on the highway is the bridge over Middle Creek, about north of the interchange with County Route 11/8 in Martinsburg. The overpass carrying the railroad tracks in Martinsburg was originally constructed in 1976.
