SR 204 begins at an intersection with US 280/SR 30 in Lanier, Georgia. It heads east through Ellabell, Georgia. It curves to the southeast and parallels the northeastern part of Fort Stewart. It has an interchange with Interstate 95, followed by an intersection with US 17/SR 25, an interchange with King George Boulevard, and an interchange with the Veterans Parkway southwest of Savannah, in Georgetown. It curves to the northeast and meets SR 204 Spur. It then continues northeast to an intersection with SR 21, which leads to I-516. Then, it meets US 80/SR 26. A short distance later, it turns left onto 37th Street, and follows that until it meets its eastern terminus, an interchange with I-16/US 17. 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. Development is more noticeable as one travels east, and there is a large collection of businesses catering to travelers at the interchange with I-95. It is at this interchange that the highway changes from two lanes to four divided lanes. 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. While there is a grade separated interchange at US 17/SR 25, there is a at-grade signalized intersection at Grove Point Road, which can cause traffic delays, as it continues closer to Savannah, it becomes a true freeway with an intersection at King George Boulevard, where the highway becomes six lanes divided, and another intersection with Veterans Parkway. The speed limit is.The route enters Savannah city limits as it crosses the Forest River. 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. SR 204 reaches its eastern terminus at the southern terminus SR 21.
The west–east portion of SR 204 east of I-95 is the only part of the road that is included within the NationalHighway System, a system of roadways important to the nation's economy, defense, and mobility.
Miscellaneous notes
In Savannah, SR 204 is a very major and heavily traveled surface arterial road and is known as Abercorn Expressway, Abercorn Street, and 37th Street.
History
The portion of the route running along Abercorn Street was previously numbered as State Route 359. SR 204 used to have its eastern terminus at a partial interchange with I-16. SR 204 continued to follow Abercorn Street north from DeRenne Ave for several blocks to its intersection with 37th Street. Here, it turned left and followed 37th Street, a four lane divided surface arterial, west for a number of blocks. Just west of its intersection with Bulloch Street, SR 204 curved right to follow the short 37th Street Connector, which leads to I-16/US 17, and thus the former end of State Route 204. The former portion of SR 204 was turned over to local control from the state highway system when the Georgia Dept of Transportation, the City of Savannah, and Chatham County agreed to add the Jimmy Deloach Parkway to the state highway system. The change went into effect February 17, 2020.
