Several other sections of US 15 were bypassed in the 1960s. The highway bypassed Lewistown in 1962, leaving behind its old alignment of Hessong Bridge Road and Angleberger Road, which became a section of MD 806. Construction on the U.S. Highway's bypass of Emmitsburg began in 1963. The following year, the portion of US 15 from the northern end of the bypass to the Pennsylvania state line opened contemporaneously with US 15's bypass of Gettysburg. The Emmitsburg bypass was completed in 1965; the old road through the town was designated US 15 Business by 1967. MD 140's overpass of US 15 was constructed in 1971; the old alignment of MD 140 was used for interchange ramps between the two highways.
