The Powerline Trail is a partnership agreement with Montgomery Parks and Exelon Corp. The current portion, completed in May 2018, is a 6-mile trail that uses the Pepco right-of-way to connect South Germantown Recreational Park with the Muddy Branch Stream Valley Park in North Potomac.
The trail begins at the Hoyles Mill Trail in South Germantown Recreational Park and meanders for roughly 2 1/2 miles until it terminates at the Seneca Creek Greenway Trail. The trail picks up again south of Seneca Creek at the Seneca Ridge Trail and continues on until just north of the Muddy Branch Creek.
