Cabin John Parkway begins at a partial interchange with Clara Barton Parkway in Cabin John that allows access to and from the direction of Washington. Each direction of the parkway crosses Cabin John Creek before the roadways come together to pass under the Union Arch Bridge, which carries both the Washington Aqueduct and MacArthur Boulevard. Cabin John Parkway crosses Cabin John Creek again before heading north as a four-lane freeway with a speed limit of 55 mph (89 km/h) through a forested corridor paralleling the creek.[1][2] After crossing Booze Creek, the two directions of the parkway divide toward their termini.[1] The northbound direction of the Cabin John Parkway splits into two ramps: one for I-495's interchange with Maryland Route 190 (River Road) and another ramp to the inner loop or northbound direction of I-495 (Capital Beltway).[1][2]
The entire route is in Montgomery County.
