'''Maryland Route 99''' ('''MD 99''' or '''Route 99''') is a {{convert|7.57|mi|km|adj=on}} section of Old Frederick Road from ] to ] in ], ], ]. It is mostly a rural, two-lane road without shoulders, though it becomes more suburban near the east end. The road is bypassed and paralleled by ] and ] to the south. '''Maryland Route 99''' ('''MD 99''') is a ] in the U.S. state of ]. Known as Old Frederick Road, the state highway runs {{convert|7.57|mi|km}} from ] near ] east to ] (US 29) in ]. MD 99 parallels the north side of ] (I-70) through a rural and suburban area in northeastern ]. MD 99, which follows the original 18th century road west from ], was constructed as part of three state highways: MD 99, the original MD 100, and MD 105. All three highways were constructed between the early 1920s and early 1930s. MD 99 originally turned south along St. Johns Lane to ] and ]; in 1956, the state highway was rerouted along part of MD 100 and all of MD 105 to downtown Ellicott City. MD 99's eastern terminus was rolled back to US 29 in two steps in the late 1970s and late 1980s.

MD 99 begins at an intersection with MD 32 (Sykesville Road) at Slacks Corner a short distance north of MD 32's interchange with I-70 in West Friendship. Old Frederick Road continues west as a county highway that parallels the north side of I-70 west to Twin Arch Road near ]. MD 99 immediately intersects the old alignment of MD 32, which is unsigned ] and named Butterfly Court. The state highway mostly follows the height of land between the watersheds of the ] to the north and the ] to the south. MD 99 passes through the communities of Alpha, which is home to ], and ], which contains Alpha Ridge Community Park. Continuing east, the state highway intersects a pair of county highways, Marriottsville Road and Woodstock Road. Marriottsville Road heads north toward the village of ] on the Patapsco River and south to junctions with I-70 and US 40. Woodstock Road heads north to the village of ], also on the Patapsco River, where the highway becomes ].<ref name="Howard HLR"/><ref name="Google Maps MD 99"/>
Old Frederick Road begins much further west than MD 99's western terminus, at Twin Arch Road, a few miles east of ]. The county-maintained road enters state maintenance at its intersection with ] north of the latter's interchange with ]. Recent development of the southeast corner of this intersection has yielded new facilities for the West Friendship Volunteer Fire Department. The fire department's access to MD 99 is directly across from an old alignment of MD 32 (now maintained as minor suffixed route MD 851J).


East of Woodstock Road, MD 99 crosses Davis Branch and enters a suburban area on the north side of Ellicott City. The state highway begins to parallel I-70 as it intersects Bethany Lane. MD 99 meets St. John's Lane, its original alignment, at the entrance to ]. MD 99 intersects Mt. Hebron Drive, which heads north toward the historic home ], before reaching its eastern terminus at the northern terminus of US 29 (Columbia Pike). US 29 heads south as a freeway through an interchange with I-70 toward ] and ]. The roadway continues east as county-maintained Rogers Avenue, which curves south toward the ] of Ellicott City. Before Rogers Avenue crosses I-70, another section of Old Frederick Road splits to the east toward ], the historic home ], and the historic ] on the Patapsco River.<ref name="Howard HLR"/><ref name="Google Maps MD 99"/>
Beyond MD 32, MD 99 runs east through rural countryside. The highway passes to the south of ] and serves as the primary access point to the school complex. It intersects the southern terminus of Henryton Road (formerly designated Maryland Route 101) before forming the northern boundary of Alpha Ridge Park, the source of the ]. It intersects a major county road, Marriottsville Road, north of the Turf Valley Country Club. Continuing east it runs into more built-up suburban neighborhoods, eventually reaching the southern terminus of Woodstock Road (formerly part of ]) before entering the western suburban outskirts of ].

Passing to the south of North Run Park, the route reaches the northern terminus of St. John's Lane, across from ]. Continuing east, the route enters the small community of ] and eventually intersects the northern terminus of ], where the MD 99 designation terminates. Across from the intersection, Rogers Avenue continues east to cross I-70 and US 40 and eventually enter historic Ellicott City, and Old Frederick Road resumes at a ] near Rogers Avenue's crossing of I-70.


==History== ==History==
Old Frederick Road was the original 18th century highway between Baltimore and the Mount Airy area. The highway, which was mostly built along the height of land between the Patapsco and Patuxent watersheds, was replaced by the more southern Baltimore and Fredericktown Turnpike, which is now MD 144, around 1812.<ref name="History of Road Building in Maryland"/> In the 20th century, the portion of Old Frederick Road east of West Friendship became part of two state highways. MD 99 was assigned to St. Johns Lane north of Frederick Road (formerly US 40 and MD 144) and Old Frederick Road from St. Johns Lane to Slacks Corner. The original MD 100, as opposed to the ] that connects Ellicott City and ], was assigned to Old Frederick Road east of St. Johns Lane. In addition, MD 105 was assigned to Rogers Avenue, which would later become part of MD 99.<ref name="1939 map"/> The first section of what was to become MD 99 was constructed as a {{convert|9|ft|m|adj=on}} wide macadam road along St. Johns Lane from Frederick Road north to Old Frederick Road by 1915.<ref name="1915 src report"/>
Previously, MD 99 continued past US 29 onto Rogers Avenue into historic downtown ], but the Rogers Avenue section has since been decommissioned. At one time, MD 99 east of St. John's Lane, including the former portion, was designated as '''Maryland Route 105''', with MD 99 following St. John's Lane south to ].


By 1923, Old Frederick Road from St. Johns Lane west to Marriottsville Road was paved in concrete and Old Frederick Road from a place called Wheelwrights Gate near the modern US 29 intersection to the Baltimore County line at the Patapsco River was reconstructed as a macadam road.<ref name="1923 map"/> Rogers Avenue was paved as a concrete road from Frederick Road near downtown Ellicott City north to near its present intersection with US 40 in 1923.<ref name="1923 map"/> Rogers Avenue was completed north to Old Frederick Road in 1924 and 1925.<ref name="1926 src report"/><ref name="1927 map"/> The next section of MD 99 to be built was a concrete road from MD 32 to Henryton Road between 1924 and 1926.<ref name="1926 src report"/><ref name="1927 map"/> This road was part of a highway to connect Slacks Corner with ] on the Patapsco River; Henryton Road later became part of MD 101.<ref name="1939 map"/><ref name="1927 map"/> The gap between Henryton Road and Marriottsville Road was closed when a concrete road was constructed in 1929.<ref name="1930 src report"/><ref name="1933 map"/> Construction began shortly after 1930 on the gap between St. Johns Lane and Wheelwrights Gate; MD 100 was completed when that section of Old Frederick Road was paved in concrete by 1933.<ref name="1930 src report"/><ref name="1933 map"/>
The current T-intersection between MD 99, Rogers Ave. and US 29 was originally intended to be an interchange, with a grade-separated freeway continuing north across the ] into ]. This freeway would have been part of the ], segments of which were built and are now signed as ] and US 29.


In 1956, St. Johns Lane and Old Frederick Road east of Rogers Avenue were removed from the state highway system, resulting in the elimination of MD 100 and MD 105. MD 99 was extended east along Old Frederick Road and south along Rogers Avenue to Frederick Road.<ref name="1956 map"/> Rogers Avenue had been reconstructed and widened to {{convert|24|ft|m}} starting in 1953, shortly before it became part of MD 99.<ref name="1954 src report"/> I-70 north of Ellicott City and US 29 from US 40 to MD 99 were constructed between 1964 and 1967.<ref name="1964 map"/><ref name="1967 map"/> MD 99 was relocated between US 29 and south of I-70 around 1966 when the state highway's bridge over I-70 was built; two sections of old alignment became segments of ].<ref name="1967 map"/><ref name="NBI MD 99 over I-70"/><ref name="Howard HLR"/> MD 99's eastern terminus was rolled back from Frederick Road to US 40 in 1978 and from US 40 to its present terminus at US 29 in 1989.<ref name="1978 map"/><ref name="1989 map"/>
Several short segments of Old Frederick Road and Rogers Avenue east of US 29 remain part of the ]'s route log; they are designated as part of '''Maryland Route 985'''.

Maryland Route 99 (MD 99) is a state highway in the U.S. state of Maryland. Known as Old Frederick Road, the state highway runs 7.57 miles (12.18 km) from MD 32 near West Friendship east to U.S. Route 29 (US 29) in Ellicott City. MD 99 parallels the north side of Interstate 70 (I-70) through a rural and suburban area in northeastern Howard County. MD 99, which follows the original 18th century road west from Baltimore, was constructed as part of three state highways: MD 99, the original MD 100, and MD 105. All three highways were constructed between the early 1920s and early 1930s. MD 99 originally turned south along St. Johns Lane to US 40 and MD 144; in 1956, the state highway was rerouted along part of MD 100 and all of MD 105 to downtown Ellicott City. MD 99's eastern terminus was rolled back to US 29 in two steps in the late 1970s and late 1980s.

Route description

MD 99 begins at an intersection with MD 32 (Sykesville Road) at Slacks Corner a short distance north of MD 32's interchange with I-70 in West Friendship. Old Frederick Road continues west as a county highway that parallels the north side of I-70 west to Twin Arch Road near Mount Airy. MD 99 immediately intersects the old alignment of MD 32, which is unsigned MD 851J and named Butterfly Court. The state highway mostly follows the height of land between the watersheds of the Patapsco River to the north and the Patuxent River to the south. MD 99 passes through the communities of Alpha, which is home to Marriotts Ridge High School, and Henryton Heights, which contains Alpha Ridge Community Park. Continuing east, the state highway intersects a pair of county highways, Marriottsville Road and Woodstock Road. Marriottsville Road heads north toward the village of Marriottsville on the Patapsco River and south to junctions with I-70 and US 40. Woodstock Road heads north to the village of Woodstock, also on the Patapsco River, where the highway becomes MD 125.

East of Woodstock Road, MD 99 crosses Davis Branch and enters a suburban area on the north side of Ellicott City. The state highway begins to parallel I-70 as it intersects Bethany Lane. MD 99 meets St. John's Lane, its original alignment, at the entrance to Mt. Hebron High School. MD 99 intersects Mt. Hebron Drive, which heads north toward the historic home Elmonte, before reaching its eastern terminus at the northern terminus of US 29 (Columbia Pike). US 29 heads south as a freeway through an interchange with I-70 toward Columbia and Washington. The roadway continues east as county-maintained Rogers Avenue, which curves south toward the historic downtown of Ellicott City. Before Rogers Avenue crosses I-70, another section of Old Frederick Road splits to the east toward Baltimore County, the historic home Linnwood, and the historic Daniels Mill on the Patapsco River.

History

Old Frederick Road was the original 18th century highway between Baltimore and the Mount Airy area. The highway, which was mostly built along the height of land between the Patapsco and Patuxent watersheds, was replaced by the more southern Baltimore and Fredericktown Turnpike, which is now MD 144, around 1812. In the 20th century, the portion of Old Frederick Road east of West Friendship became part of two state highways. MD 99 was assigned to St. Johns Lane north of Frederick Road (formerly US 40 and MD 144) and Old Frederick Road from St. Johns Lane to Slacks Corner. The original MD 100, as opposed to the modern freeway that connects Ellicott City and Glen Burnie, was assigned to Old Frederick Road east of St. Johns Lane. In addition, MD 105 was assigned to Rogers Avenue, which would later become part of MD 99. The first section of what was to become MD 99 was constructed as a 9-foot (2.7 m) wide macadam road along St. Johns Lane from Frederick Road north to Old Frederick Road by 1915.

By 1923, Old Frederick Road from St. Johns Lane west to Marriottsville Road was paved in concrete and Old Frederick Road from a place called Wheelwrights Gate near the modern US 29 intersection to the Baltimore County line at the Patapsco River was reconstructed as a macadam road. Rogers Avenue was paved as a concrete road from Frederick Road near downtown Ellicott City north to near its present intersection with US 40 in 1923. Rogers Avenue was completed north to Old Frederick Road in 1924 and 1925. The next section of MD 99 to be built was a concrete road from MD 32 to Henryton Road between 1924 and 1926. This road was part of a highway to connect Slacks Corner with Henryton on the Patapsco River; Henryton Road later became part of MD 101. The gap between Henryton Road and Marriottsville Road was closed when a concrete road was constructed in 1929. Construction began shortly after 1930 on the gap between St. Johns Lane and Wheelwrights Gate; MD 100 was completed when that section of Old Frederick Road was paved in concrete by 1933.

In 1956, St. Johns Lane and Old Frederick Road east of Rogers Avenue were removed from the state highway system, resulting in the elimination of MD 100 and MD 105. MD 99 was extended east along Old Frederick Road and south along Rogers Avenue to Frederick Road. Rogers Avenue had been reconstructed and widened to 24 feet (7.3 m) starting in 1953, shortly before it became part of MD 99. I-70 north of Ellicott City and US 29 from US 40 to MD 99 were constructed between 1964 and 1967. MD 99 was relocated between US 29 and south of I-70 around 1966 when the state highway's bridge over I-70 was built; two sections of old alignment became segments of MD 985. MD 99's eastern terminus was rolled back from Frederick Road to US 40 in 1978 and from US 40 to its present terminus at US 29 in 1989.
