MD 347 begins at an intersection with MD 349 (Nanticoke Road) in Quantico. The state highway heads north as two-lane undivided Quantico Road past scattered residences and runs east of Westside Primary School. After veering northwest at Catchpenny Road, MD 347 crosses Quantico Creek and passes through the historic center of Quantico. The state highway leaves Quantico after a sharp turn to the northeast at Old Athol Road and passes through farmland. Upon arriving in the town of Hebron, the highway passes southeast of Westside Intermediate School and the historic home
St. Giles. Within Hebron, MD 347 is known as Main Street and intersects the western terminus of
MD 670 (Lillian Street). After leaving Hebron, the state highway continues northeast as Hebron Road, crossing Rewastico Creek before reaching its northern terminus at US 50 (Ocean Gateway). ==History==
