  • Aims to improve mobility and safety for commuters, freight and other travelers

About the Study

The I-526 LCC EAST began in the spring of 2018 as a set of planning studies to conduct existing conditions reports on traffic, safety and condition of the infrastructure. Since that time, the I-526 LCC EAST transitioned formally to a Planning & Environmental Linkages (PEL) study. An initial public meeting was held in 2020 to help define the needs of the corridor. A second public meeting was held in late 2021 to present the analysis completed to-date and the reasonable alternatives and to ask for additional feedback. Input received during this process helped establish the purpose, needs, and priorities for future improvements within this corridor. 

The PEL study provides a collection of possible projects and estimated costs for consideration as part of SCDOT’s future statewide transportation plans. Recommendations are also available for other project partners to consider for implementation in local efforts. If and when projects are funded, they would advance to the environmental phase, NEPA. During that process, the range of alternatives would be further refined and narrowed down to a recommended preferred alternative based on additional studies, engineering design, and public input. The first of such projects is the I-526 @ Long Point Road Interchange Improvements project. Learn more here.
