State Route 6 Corridor Study Final Report - Cobb County Government

The Lee, Sweetwater, and Hiram‐Lithia Springs Roads concept includes widening the
roadway to six lanes from I‐20 to US 78 and to four lanes from US 78 to SR 6. Douglas
County is currently undertaking design to widen and realign Lee and Sweetwater
Roads. According to the Technical Memorandum: Lee Road/South Sweetwater Road Corridor
Analysis (December 2004), Lee and South Sweetwater Roads are to be designed as a
four‐lane divided roadway from I‐20 to Skyview Drive. An alternate three‐lane section,
with a dual left‐turn lane, will be developed from Skyview Drive to US 78 due to
constraints on roadway widening from adjacent historical properties. Douglas County
staff indicated that the concept includes a sidewalk on one side of the road and a multi‐
use path on the other side. Both North Sweetwater Road and Hiram‐Lithia Springs
Road were identified as part of the statewide bicycle route network, Central Route 15.
The Douglas County widening project is currently programmed for 2010.
The current Lee, Sweetwater, and Hiram‐Lithia Springs Road concept breaks the project
into three sections:
• Widening Lee and Sweetwater Road to six lanes from I‐20 to US 78;
• Widening Hiram‐Lithia Springs Road to four lanes from US 78 to Brownsville
Road; and
• Realigning and extending Hiram‐Lithia Springs Road from Brownsville Road to
SR 6, connecting to SR 6 in the vicinity of Old Dallas Highway.
Eight to ten‐foot‐wide multiuse side paths are envisioned to accompany the widening
as is a landscaped, 20‐foot median, as illustrated in Figure 3‐3. Access management
strategies should be employed to minimize curb cuts or driveways to protect through‐
put capacity for vehicular travel and reduce potential conflict points of persons using
the multiuse trail at trail crossings. From review of the area, it is recognized that
existing historic and new developments may place constraints on the widening. To
avoid potential impacts to historic properties in Lithia Springs, a narrower typical
section should be used or the roadway should be diverted around this area. Care
should be taken to minimize impacts to adjacent development.
