[1] The highway is two lanes as it travels east through rural Bryan County and the Ellabell community.
Once it crosses the Ogeechee River and enters Chatham County, the highway becomes known as Fort Argyle Road.
Traffic is often quite heavy as SR 204 is the major route from I-95 into the busy south side of Savannah.
Though SR 204 is known as Abercorn Expressway as it enters Savannah, it is not a freeway until after it passes through a signal at Grove Point Road.
At the signaled intersection with Rio Road, adjacent to the Savannah Mall, the highway loses its controlled access.
As the route continues through the south side of Savannah it has an interchange where the Harry S. Truman Parkway begins.
