MD 925 and the county-maintained portion of Old Washington Road to the north comprise the old alignment of U.S. Route 301 (US 301) in northern Charles County.

MD 925 heads northeast as a two-lane undivided road through a residential area, paralleling US 301 to the west and CSX's Popes Creek Subdivision railroad line to the east.

The route passes northwest of a park and ride lot serving MTA Maryland commuter buses before intersecting Smallwood Drive in St. Charles.

Shortly after this intersection, the state highway expands to a three-lane road with a center left-turn lane and enters a commercial area.

[1][2] Old Washington Road is the original alignment of US 301 from White Plains through Waldorf to the Prince George's County line.
