context_page_description: Cabin John Parkway is an automobile parkway in the U.S. state of Maryland. The parkway runs 1.50 miles from Clara Barton Parkway in Cabin John north to Interstate 495 in Bethesda in southwestern Montgomery County. Cabin John Parkway is a four-lane freeway that serves as a connector between Clara Barton Parkway in the direction of Washington and I-495 in the direction of Rockville and Silver Spring. The parkway was constructed in the mid-1960s.
context_section_description: Construction on Cabin John Parkway began in 1962 when I-495's bridge across Cabin John Creek and the southbound ramp to the parkway was built. Work on the remainder of the parkway was underway by 1963. Cabin John Parkway opened in 1965 when the Clara Barton Parkway (then known as the Maryland portion of the George Washington Parkway) from the Cabin John interchange east to the MacArthur Boulevard interchange opened.
