Miscellaneous notes In Savannah, SR 204 is a very major and heavily traveled surface arterial road and is known as Abercorn Expressway, and Abercorn Street. Before the truncation in 2020, the route was also known as 37th Street. History The portion of the route running along Abercorn Street was previously numbered as State Route 359. In 2020, SR 204 was truncated south to a shared end point with SR 21 (DeRenne Avenue). The previous alignment extended north along Abercorn Street through Midtown Savannah to 37th Street. SR 204 lined 37th Street west to the 37th Street Connector with I-16. Major intersections Savannah spur route State Route 204 Spur (SR 204 Spur) was a spur route of SR 204 that connected the mainline to Skidaway Island. Segments of SR 204 Spur are named Montgomery Cross Road, Waters Avenue, Whitfield Avenue, Diamond Causeway, and Tidewater Way. SR 204 Spur was turned over to local control as part of the deal with the Georgia Department of Transportation that extended SR 17 onto the Jimmy DeLoach Parkway and truncated the eastern terminus of SR 204 to SR 21. SR 204 Spur was not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
