MD 94 heads northeast as two-lane undivided Woodbine Road and passes through Patuxent River State Park as it ascends out of the narrow river valley and passes to the west of a steep hill named Annapolis Rock.

[3] A concrete arch bridge across the Patapsco River at Woodbine was completed in 1917; a macadam road was constructed north 1 mile (1.6 km) into Carroll County by 1921.

[5][6] The macadam road in Carroll County was extended north 1 mile (1.6 km) to the hamlet of Day in 1928.

[5][7] MD 94 in Carroll County was extended north in two sections from Day to the village of Daniel starting shortly after 1930; this macadam road was completed to near Buckhorn Road a short distance south of MD 26 in Winfield by 1933.

[11] The state highway previously had a short concurrency with MD 144 in Lisbon between the road south to Florence and the highway north to Woodbine; the old alignment remains south of I-70 as Madison Street and north of the Interstate as Old Woodbine Road.
