At an interchange with Washington Boulevard (VA 27), the road turns west again and continues in that direction for the remainder of its length.

VA 237, which arrives at the circle as Lee Highway concurrent with US 29, also concurs with US 50 on Arlington Boulevard for less than 1/3 mile before turning south onto Pickett Road.

The trail runs from N. Rhodes Street in Arlington County to Fairview Park Drive in Falls Church.

In May 1979, the trail was extended east from its endpoint at North Pershing, around Fort Myer to Arlington Memorial Bridge.
