SECESSIONVILLE ROAD


Purpose

Located in the Town of James Island, the need for intersection improvements along Fort Johnson Road (S-94) at Secessionville Road (S-387) has been identified. The primary goal of this project is to increase safety for all modes of transportation while improving traffic flow. Charleston County, the City of Charleston, the Town of James Island, and the South Carolina Department of Transportation (SCDOT) have made improving this intersections a priority because of the 40 accidents that have occurred over a 5-year period.

The County has studied various improvement alternatives and their associated impacts to the natural and built environment within the study area. These studies include evaluating various types of improvements, including the installation of traffic signals and a roundabout.

Top Reoccuring Comments

50 comments concerned that the installation of a traffic signal will result in traffic back-ups...
A traffic analysis indicates that the recommended alternative, a traffic signal, will perform better than a roundabout in the afternoon peak hours...

12 comments regarding sidewalk or bike/pedestrian concerns.
Construction will include keeping existing sidewalks in place and adding proposed sidewalks where there is not property owner opposition...

12 comments requesting a timeline for the project.
The project team anticipates construction beginning in the 1st quarter of 2021...

12 comments questioning the design of the roundabout.
The roundabout design is skewed from the current center of the intersection... The angle of the intersection limits the ability to design a true roundabout.

Decision Rationale

Thank you for your public comments. While Charleston County recognizes that the community slightly favors Alternative 2, the Public Works Department has to consider the social impacts and relocations the construction of a roundabout would have over the installation of a traffic signal. Alternative 2 would result in relocating a home on the northeast corner of the intersection. Alternative 2 would also require the majority of parking for the James Island Kingdom Hall of Jehovah’s Witnesses... Charleston County Public Works will proceed with Alternative 1, a traffic signal.
