VPIM East 2021



Public Meeting Overview

The I-526 Lowcountry Corridor EAST Public Information Meeting ended December 1, 2021. ALL Public Information Meeting materials are still available online below. In-person opportunities to participate were held on:

  • Tuesday, October 26, 5-7 PM, R. L. Jones Center (391 Egypt Road, Mount Pleasant, SC)
  • Wednesday, October 27, 5-7 PM, Felix C. Davis Community Center (4800 Park Circle, North Charleston, SC – CARTA Routes 13 & 104)

These drop-in Public Information Meetings took place partially indoors and partially outdoors. These open house meetings did not have a formal presentation. The City of North Charleston required masks inside their buildings. Masks were highly encouraged when not required. The COVID-19 conditions were continually monitored. In accordance with current public health guidelines, temperature checks were performed at all meetings. Anyone with a temperature of over 100.4 was not allowed to enter the facility. 

The purpose of the Public Information Meeting was to:

  • Explain how YOUR input has been used to inform the concepts development and screening process
  • Ask for your input on the Reasonable Alternatives
  • Outline the next steps in the project development process 
  • Gather information on historic or cultural resources and any potential impacts

Project Background 

SCDOT is conducting a Planning & Environmental Linkages (PEL) Study for the I-526 Lowcountry Corridor EAST (I-526 LCC EAST), which extends along I-526 from Virginia Avenue in North Charleston to approximately US 17 in Mount Pleasant. The PEL study examines existing and projected transportation issues within the corridor based on the input YOU provided during the 2020 public information meeting and survey. Your input validated the data we gathered and was used to develop the draft Purpose and Needs.

Growing Mobility Needs

Our region is experiencing several trends affecting transportation, such as population growth, job creation, and changing technology and transportation preferences. With the increased number of vehicles anticipated, the current traffic congestion is expected to increase throughout most of the corridor if no improvements are made. Below, explore more about these growing challenges along the corridor, including what traffic might be like if no improvements were made.

Concepts Development & Screening Process

Based on your input, we developed several types of concepts. These range from the “do nothing” or “no build” alternative, to alternatives designed to alleviate the demand on the corridor, to an alternative, parallel route. After those concepts were explored, we also evaluated how many lanes might be needed.

The alternative concepts were evaluated through a three-step screening process to identify the reasonable alternatives that are presented here today. Each level of screening included a more detailed analysis of the alternatives. As the process progressed, poorly performing alternatives were removed from further review. The resulting alternatives, known as the Reasonable Alternatives, are proposed to be carried forward into the National Environmental Policy Act (NEPA) process.

Next Steps & Comment

This study will be used to establish a vision for the corridor that will guide future transportation improvement projects. Results of the PEL study will be carried forward into the next phase of the project development process, the NEPA process. After the needs are better understood in this corridor, and potential improvements identified, potential phasing and project opportunities, can be developed.

Meaningful input is our number one priority. The official comment period ended December 1, 2021.
