MD 67 begins at a
trumpet interchange with US 340 (Jefferson Pike) in Weverton within the
Potomac Water Gap near Harpers Ferry. The two-lane undivided highway crosses Israel Creek and heads north through the Pleasant Valley, the valley of Israel Creek between Elk Ridge to the west and South Mountain to the east. Just north of Israel Creek, MD 67 intersects MD 67D, a connector east to Weverton Road that provides access to the
Appalachian Trail at the Weverton Cliffs within
South Mountain State Park. Within the hamlet of Garretts Mill, the highway intersects Garretts Mill Road, which heads west toward the
Robert Clagett Farm and the
Magnolia Plantation, and receives the other end of Weverton Road, which is accessed via MD 67E. MD 67 passes along the edge of
Brownsville, which is served by parallel Boteler Road, which uses MD 67C to rejoin MD 67 north of Brownsville. MD 67 continues north around the village of
Gapland, access to which is provided by Gapland Road. Gapland Road also heads east to
Crampton's Gap, a mountain pass through South Mountain that provides access to
Burkittsville in the
Middletown Valley. Crampton's Gap is the site of the
Battle of Crampton's Gap,
Gathland State Park, and the
National War Correspondents Memorial. MD 67 crosses Israel Creek near its headwaters, enters the valley of Little Antietam Creek, and approaches Rohrersville. The highway bypasses the village to the east, during which the route crosses Little Antietam Creek; MD 858F (Main Street) loops through the village. The valley widens as MD 67 approaches Rohrersville. MD 67 continues north through
Locust Grove and to the west of
Park Hall, which contains
Kefauver Place. The highway parallels another loop, Mount Carmel Church Road, which leads to the
Nicodemus Mill Complex, as the route crosses Dog Creek. MD 67 passes east of a
park and ride lot and enters the town of Boonsboro immediately before it reaches its northern terminus at a
roundabout with US 40 Alternate (Boonsboro Pike). ==History==
