intersection with St. Anthony and
Orndorff roads south of Mount St. Mary's University to just south of the Pennsylvania state line near Emmitsburg. This section of divided highway was extended south through the MD 550 interchange in 1983. As part of this project, the oblique intersection with MD 806 on the north side of Thurmont was removed. MD 806 was moved onto Albert Staub Road, which was extended north over a new crossing of Owens Creek to its present terminus at Roddy Creek Road, where local traffic could access US 15 at a perpendicular intersection. The two-lane highway between Lewistown and MD 550 was expanded to a four-lane divided highway in 1985. The MD 77 interchange was completed with the construction of the southbound US 15 ramps in the southwest quadrant of the junction. A third interchange was added on the south side of Thurmont as a connector between US 15 and MD 806 in 1985 as well. US 15's expansion to a four-lane divided highway north of Frederick was completed in 1989 when the piece of highway at the Pennsylvania state line was expanded to four lanes contemporaneous with the four-laning of the Gettysburg bypass.

Frederick to 9 at the highway's interchange with MD 26; the 7th Street interchange became exit 7A. The two-lane section of the freeway was expanded to its present four-lane configuration in 1969, the same year the US 340 freeway was completed between Jefferson and Frederick. US 15's present alignment from Point of Rocks to US 340 was also under construction by 1969. When the new highway opened in 1970, US 15 was moved to the new highway and joined US 340 in a concurrency along Jefferson National Pike from Jefferson to the Frederick Freeway. The old section of US 15 from Point of Rocks to Tuscarora became a westward extension of MD 28. Buckeystown Pike from MD 28 to Washington National Pike was designated MD 85, which was extended north to MD 355 the following year. The U.S. Highway's interchange with Mt. Zion Road opened in 1972.

MD 26 was placed under construction in 1956. The highway was constructed as a two-lane freeway from just south of its interchange with
Rosemont Avenue to its northern end near Hayward Road, where the freeway tied into existing US 15 at Harmony Grove. The freeway north of Patrick Street featured interchanges with Rosemont Avenue, Motter Avenue, and a westward extension of MD 26. When the Frederick Freeway opened in 1959, US 15 was moved to Washington National Pike north of Buckeystown Pike and north through Frederick along the Frederick Freeway. Market Street north of Evergreen Point through downtown Frederick to US 15 north of the city became a northward extension of MD 355; the section of Buckeystown Pike from the freeway to Evergreen Point became a section of MD 806.

The interchange between Jefferson National Pike and the Frederick Freeway was transformed from a cloverleaf to a partial cloverleaf interchange in 2004. Access between US 15 and the northern end of MD 355, then named Wormans Mill Road, was removed in 2006, the same year a ramp was added from westbound MD 26 to northbound US 15. The roundabout at the US 15–MD 464 intersection in Point of Rocks was built in 2009.

US 15's last intersection in Maryland is with the northern end of US 15 Bus.

North of the intersection, US 15 becomes a four-lane freeway that continues across the Pennsylvania state line as the U.S. Highway's bypass of Gettysburg.

the piers of the old bridge were removed from the river by
September of that year. The new bridge and its approaches, which crossed over the Baltimore and Ohio Railroad on the Maryland side, opened December 26, 1937. The camelback truss bridge spans 1,689 feet (515 m) and has a 24-foot-wide (7.3 m) roadway and a pair of three-foot-wide (0.91 m) sidewalks. US 15 followed a temporary approach to the new bridge along Commerce Street that remained vulnerable to major floods. The U.S. Highway was moved to higher ground on Clay Street when the highway was reconstructed and widened from Point of Rocks to Tuscarora in 1949.

As part of this project, US 15's intersection with Hayward Road was removed, resulting in the northern end of US 15's freeway section being extended from MD 26 to Tuscarora Creek. The interchange with Monocacy Boulevard/Christophers Crossing was completed in 2018. In 2015, an interchange opened at Jefferson Technology Parkway.

In 1956, construction began on the Thurmont Bypass, which was constructed as the first carriageway of an ultimate divided highway from south of Catoctin Furnace to just south of Owens Creek. The bypass, which included an interchange with MD 77, was completed in 1958. The MD 77 interchange originally consisted of one two-way ramp in the northeast quadrant of the junction. The old alignment of US 15 through Catoctin Furnace and Thurmont was designated MD 806 by 1960. US 15's interchange with MD 550 was built in 1972.

In 1926, the MDSRC assumed maintenance of and resurfaced Market Street with asphalt from the city of Frederick between the south city limit at New Design Road (now Stadium Drive) to the north city limit at 9th Street.
