The following questions are the most frequently asked about the Carolina Crossroads I-20/26/126 Corridor Project. This list will be updated from time to time as the project progresses to include new questions that come up. If you do not see an answer to your question, please Contact Us.
What alternatives have you selected?
No preferred alternative has been selected at this point in the process. A number of Reasonable Alternatives will be presented to the public for input in September 2017.
In an effort to identify a solution that will benefit the I-20/26/126 corridor, SCDOT looked at the range of alternatives developed throughout 2015-2016. The range of alternatives were developed based on public input and past studies and included various transit and roadway options.
To target the most complex areas of the system, SCDOT has evaluated and presented 49 design options at each of the 12 different interchanges along the system. The public also asked that a northern alignment and improvements to the existing roadway network be evaluated. After receiving public input on all of these options, SCDOT has been working to evaluate the best interchange solutions to develop Reasonable Alternatives that will be evaluated in the Draft Environmental Impact Statement (DEIS).
Several modes of transportation including transit were considered in developing the preliminary alternatives. While mass transit provides some relief to traffic, it does not solve the issues in the corridor today as a standalone solution. For more information, view the project’s Purpose and Need Report on our website at http://www.scdotcarolinacrossroads.com/#project-resources.

Are you going to impact my home or business?
Impacts to homes or businesses will not be fully determined until a Preferred Alternative has been selected. A number of Reasonable Alternatives will be presented to the public for input in September 2017. After receiving public input on all of these alternatives, Reasonable Alternatives will be evaluated in the Draft Environmental Impact Statement (DEIS). A public hearing on the DEIS is anticipated for fall 2017/winter 2018 and a Preferred Alternative will be presented.
Right-of-way (ROW) acquisition is not anticipated to begin until 2019. At that time, should ROW be required, SCDOT will work with affected property owners based on third-party property valuations and according to the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 http://www.fhwa.dot.gov/real_estate/uniform_act/). Fair market value is the estimated value of a property based on what a reasonable person would pay in a voluntary transaction. Also, our online brochure, Highways and You, can help answer questions about the process if property acquisition is needed (http://www.scdot.org/doing/technicalPDFs/rightOfWay/HighwaysandYou.pdf).
In extraordinary cases or emergency situations, SCDOT may request and the Federal Highway Administration (FHWA) may authorize the acquisition of a particular property or a limited number of properties within the proposed highway corridor prior to completion of processing the final EIS. These requests will be handled on a case by case basis.
Who is making the decision about the alternatives?
The I-20/26/126 corridor is a complex interstate system made up of 19 bridges, 12 interchanges, and 14 miles of interstate. More than 130,000 vehicles travel this system every day. SCDOT and the Federal Highway Administration (FHWA) are facilitators of the process that will evaluate and narrow all available alternatives to solve the transportation problems in the corridor today.
The process to review alternatives is an Environmental Impact Statement (EIS) which is a document required by the National Environmental Policy Act (NEPA) to promote informed decision-making by federal, state and local agencies by making "detailed information concerning significant environmental impacts" available to both agency leaders and the public. Through the EIS process, NEPA encourages communication and cooperation between those who are involved in project-related decision making, including government officials, private businesses, and the public.
The NEPA process began in July 2015.
- A community kickoff meeting was held on May 12, 2015 to introduce the project and the project team.
- On September 10, 2015, a public input meeting was held to provide updated information on the project, process, and schedule. At this time, the public was also informed about the purpose and need of the project.
- On October 4, 2016, an alternatives input meeting was held to get input on 49 design options at each of the 12 different interchanges along the system. The public also asked that a northern alignment and improvements to the existing roadway network be evaluated.
After receiving public input on all of these options, SCDOT has been working to connect the best interchange solutions to develop Reasonable Alternatives that will be evaluated in the Draft Environmental Impact Statement (DEIS). Reasonable Alternatives will be developed by connecting the best interchange designs that have the most improvement to traffic in the entire system. Interchange alternatives will be advanced or dismissed for a variety of reasons including cost, social and economic impacts, and environmental concerns. Some interchanges may not need improvement at all.
Reasonable Alternatives have not yet been completed. The Reasonable Alternatives will be presented to the public in September 2017 and will feature more details.
How are alternatives evaluated?
Reasonable alternatives will be evaluated on a variety of criteria, including cost, social and economic impacts, and environmental considerations. The key factors to consider are how each potential alternative improves local mobility, enhances traffic operations, and accommodates future traffic needs. Alternatives will be advanced or dismissed for a variety of reasons including cost, social and economic impacts, and environmental concerns.
SCDOT and the Federal Highway Administration (FHWA) will review all comments received during the NEPA process. SCDOT will host a public information meeting to present the reasonable alternatives in September 2017. A public hearing on the DEIS is anticipated for fall 2017/winter 2018, and a Final EIS and Record of Decision (ROD) on the Recommended Preferred Alternative issued in 2018.
Will access to my home or business be impacted?
The Preliminary Alternatives provided at this stage do not determine if access to individual homes or business will be impacted. As the study moves forward, alternatives will be evaluated and retained or eliminated based on their benefit to traffic congestion, weighted against their impacts to the human and natural environment. More detailed information will be available as the study progresses.
What federal, state, and local agencies are you working with?
SCDOT, in coordination with the Federal Highway Administration (FHWA), is working collaboratively with other agencies on the development of the Environmental Impact Statement (EIS). It is critical to work with agency partners to fuse the environmental and planning processes and to merge the FHWA, NEPA, and related project development procedures with other federal, state, and local requirements. The process continues to actively involve partners and affected parties in an open, cooperative, and collaborative process, beginning at the planning stages and continuing through project development, construction, and operations.
What is the cost of the project?
As the #1 statewide interstate priority, SCDOT plans to fund this project for construction using a blended funding approach that combines a Federal-Aid Interstate Program, as well as leveraging new revenue streams approved by the Legislature in 2016. On June 8, 2016, Governor Nikki Haley signed Act 275 of 2016 which will provide essential funding to roadway and bridge projects throughout the state, including funding to deliver the Carolina Crossroads I-20/26/126 Corridor Project. The project is expected to cost between $1.3 and $1.5 billion. The project budget was estimated using a detailed cost and schedule risk assessment. As alternatives are developed and analyzed, the project team will develop cost estimates, funding strategies, and timelines for completion.
Are you going to impact wetlands or waterways?
An Environmental Impact Statement (EIS) is a document required by the National Environmental Policy Act (NEPA) to promote informed decision-making by federal, state and local agencies by making "detailed information concerning significant environmental impacts" available to both agency leaders and the public. Through the EIS process, NEPA encourages communication and cooperation between those who are involved in project-related decision making, including government officials, private businesses, and the public.
The EIS will include water quality analyses and consultations with the federal, state and/or local agencies responsible for water quality. SCDOT will identify streams and water bodies which may be impacted by the project and will identify mitigation measures to minimize potential direct impacts to water quality. The EIS will also consider the potential effects of nonpoint source pollution, such as roadway runoff, to water quality and will describe impact avoidance, minimization and mitigation measures, as applicable.
What will you do to reduce the noise from the roadway to my home or business?
Construction of noise walls (barriers) or other abatement measures are based on feasibility and reasonableness. “Feasibility” is determined by acoustic, physical, and/or engineering constraints. “Reasonableness” is based on noise reduction, cost effectiveness, and viewpoints of benefited residents and/or owners.
To learn more about SCDOT’s process in evaluating noise on a project like the Carolina Crossroads I-20/26/126 Corridor Project, watch our video at http://www.scdotcarolinacrossroads.com/#project-resources and select the SCDOT – Noise video under the Videos section.
The Carolina Crossroads I-20/26/126 Corridor Project team has implemented a Noise Advisory Board made up of community representatives in the project corridor. The role of the Noise Advisory Board is to provide a better understanding of the noise evaluation process, a two-way communication loop between the community and project team, and to review outcomes of the noise analysis process.
