College Park Road/Ladson Road Intersection Alternatives
In 2019, after reviewing traffic studies for the Lowcountry Rapid Transit project, Charleston County identified that the 3 intersections at Hwy 78 at College Park Road, Hwy 78 at Ladson Road, and Ladson Road at College Park Road are key to traffic delays experienced in the corridor. Conceptual studies for improvements at those intersections were developed to study in more detail as part of the Hwy 78 project design and NEPA evaluations. The traffic study that was completed before the Hwy 78 Project began included four alternatives consisting of multiple configurations were proposed to help alleviate current congestion experienced at these intersections and a traffic analysis was performed to review each configuration. It was found that Alternative 2 and Alternative 4, as presented here, would provide reduced traffic backups in the design year of 2045. One of these two alternatives will be selected based on traffic analysis, impact analysis, costs, and public input and will be incorporated in alternatives for the overall corridor.
Below is a summary of the improvements of the 2 alternatives with graphics on the following sheets.
