Georgia State Route 204
State Route 204 (SR 204) is a state highway in the east-central part of the U.S. state of Georgia. It runs from a point east of Pembroke and ends in Savannah. Its routing is located within portions of Bryan and Chatham counties. Route description. SR 204 begins at an intersection with US 280/SR 30 in Lanier. 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 (I-95), followed by an interchange with US 17/SR 25 (Ocean Highway ), an interchange with King George Boulevard, an interchange with the Veterans Parkway (also known as the Southwest Bypass) and an interchange with Harry S. Truman Parkway in the southwest of Savannah. It curves to the northeast and meets the former SR 204 Spur (Montgomery Cross Road). It then continues northeast to meet its eastern terminus at an intersection with the southern terminus of SR 21 (DeRenne Avenue). 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 interchange at King George Boulevard (which used to be a signal), where the highway becomes six lanes divided, and another interchange 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. It remains six lanes until an intersection with DeRenne Avenue, where it meets its eastern terminus. Roadway continues as 4 lanes past its terminus. National Highway System. The west–east portion of SR 204 east of I-95 is the only part of the road that is included within the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
