Maryland Route 79 (MD 79) is a state highway in the U.S. state of Maryland. Known as Petersville Road, the state highway runs 1.81 miles (2.91 km) from MD 17 and MD 464 in Rosemont north to MD 180 in Petersville. MD 79 and the adjacent portion of MD 17 south to Brunswick were constructed in 1916. The state highway reached its present extent in 1968.

Route description[edit]

MD 79 begins at a four-way intersection on the boundary between the town of Brunswick to the south and the village of Rosemont to the north. Petersville Road continues south as MD 17 into Brunswick; MD 17 also heads west along Burkittsville Road. The eastern leg of the intersection is MD 464 (Souder Road). MD 79 heads northeast as a two-lane road through a residential area where the highway meets the eastern end of Rosemont Drive, which is unsigned MD 871G. The state highway leaves Rosemont as it crosses Little Catoctin Creek. MD 79 continues through farmland, making a sharp curve to the north before reaching its northern terminus at MD 180 (Jefferson Pike) in Petersville.[1][2]


Petersville Road was constructed as a 14-foot (4.3 m) wide macadam-surfaced highway from Jefferson Pike (designated U.S. Route 340 and later MD 180) south to Brunswick in 1916.[3] When state highways were first numbered in Maryland in 1927, the portion of Petersville Road south of what is now Rosemont Drive became MD 33; MD 33 became MD 17 in 1940.[4][5] Petersville Road from Rosemont north to Petersville was later marked as MD 79.[6] MD 79's modern bridge over Little Catoctin Creek was built in 1941 after the previous bridge was carried away by a flood that year.[7] MD 79 was extended south to its current southern terminus in 1968 when MD 17 was relocated to its present course through Rosemont and MD 464 was extended west along Souder Road to its present terminus to form the fourth leg of that intersection.[8]
