Columbia provided professional services for the safety improvements to Hope Hollow Road for the Gwinnett County Department of Transportation (GCDOT).
The project kicked-off with a Stakeholders Meeting attended by local residents, GCDOT Officials, City of Grayson Officials, and Columbia staff to discuss the scope of the proposed realignment as well as potential traffic calming measures. Input from all Stakeholders was taken into account and implemented into the design scope for the safety improvement project. The 0.7-mile project consists of correcting the sub-standard horizontal alignment along Hope Hollow Road, designing two (2) traffic calming islands along Hope Hollow Road to control the speed of vehicles traveling along this section of Hope Hollow Road, and relocation of Hope Hollow Lane at its intersection with Hope Hollow Road in order to improve its angle of intersection. Cost savings were realized for this project with avoidance of a conflict with a major 48” prestressed concrete cylinder pipe (PCCP) water distribution line. Hope Hollow Lane’s vertical alignment was designed to avoid impacting the 48” PCCP water line, thus eliminating costs associated with a conflict.
