Virginia State Route 99

State Route 99 (SR 99) is a primary state highway in the U.S. state of Virginia. The state highway runs 5.20 miles (8.37 km) from the north town limit of Pulaski east to SR F-047 just east of Interstate 81 (I-81) and SR 100 at McAdam.

Route description

SR 99 begins at the north town limit of Pulaski. The highway continues north into unincorporated Pulaski County as SR 738 (Robinson Tract Road). SR 99 heads south as two-lane Randolph Avenue. At the west edge of downtown, SR 99 splits into a one-way pair. Westbound SR 99 turns onto Randolph Avenue from 3rd Street while eastbound SR 99 turns from Randolph Avenue onto Main Street, which parallels Peak Creek through downtown. Each direction of SR 99 follows two-way streets east to Jefferson Avenue, where both Main and 3rd become one-way. One block to the east, SR 99 intersects U.S. Route 11 (Washington Avenue). Two blocks east of US 11, Main Street becomes a four-lane divided highway as the two directions of the state highway come together. SR 99 gains a median west of Bob White Boulevard, where the highway reduces to two lanes, begins to curve to the south, and crosses Norfolk Southern Railway's Pulaski District and Peak Creek. At the east town limit of Pulaski, the state highway becomes Count Pulaski Drive, which expands to a four-lane divided highway shortly before reaching its partial cloverleaf interchange with I-81 and SR 100 and, just to the south, its eastern terminus at SR F-047 (Kirby Road) in the hamlet of McAdam.

Maryland Route 99

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.
