Bradley Boulevard continues west as a county highway along the edge of Congressional Country Club to its end at Persimmon Tree Road, which connects Potomac with Cabin John.

The named road's terminus is near another golf course, the TPC Potomac at Avenel Farm.

MD 191 passes to the north of Burning Tree Club, then curves southeast through the western parts of Bethesda.

The state highway continues east as Bradley Lane, a narrow two-lane undivided street that passes between Chevy Chase Country Club to the south and the town of Chevy Chase to the north.

[10] By 1962, the divided highway had been extended another half-mile westward to near MD 614 (Goldsboro Road).

[11][12][13][14] MD 191 and Eggert Drive were moved at the site of the Persimmon Tree Road bridge and a cut-off county road was built to form a four-way intersection just north of a bridge built to carry MD 191 across the Beltway.
