A public information meeting will be held on Thursday, September 19, 2019, from 5:00 pm - 7:00 pm at the Boys & Girls Club of Hilton Head Island (151 Gumtree Road, Hilton Head Island).

This meeting will be conducted in an “open house” format, and there will be a video presentation starting approximately every 5 minutes. The purpose of the meeting is to:

  • Share with the public the proposed roadway improvements;

  • Provide an opportunity to discuss the proposed US 278 Corridor Improvements project individually with representatives of the South Carolina Department of Transportation (SCDOT);

  • Provide an update to the community on the project; and

  • Gather input from the public or any interested organization.

We value your input and would like to hear from you. Please use the comment form to submit your message about the project. While we accept comments throughout the project development process, the formal comment period for this public meeting has been extended until October 25, 2019.

Project Background

The purpose of this project is to address structural deficiencies at the existing eastbound Mackay Creek bridge, to increase capacity, and reduce congestion along US 278 from Moss Creek Drive to Spanish Wells Road.

 

Watch SCDOT’s NEPA and the Decision-making Process video to learn more about how projects are taken from design to construction, and also through the National Environmental Protection Act (NEPA) process.

Alternatives Evaluation

Currently, the 17 preliminary alternatives have been reduced to 6 reasonable alternatives plus the no-build option. The following resources inform how these 17 alternatives were evaluated, the resulting reasonable alternatives, and how these alternatives will be further refined to identify the preferred alternative which will be presented at the public hearing in late 2020.

Public involvement is an integral component to this process. It helps the project team identify cultural or historical sites and environmental resources, as well as how these alternatives impact various communities. In fact, feedback received previously helped to generate the preliminary range of alternatives.

Alternatives Evaluation Criteria Matrix

How did the alternatives compare based on identified criteria?

The Alternatives Evaluation Criteria Matrix outlines in detail the comparison of each alternative. View this PDF to see how each alternative compares.

Preliminary Range of Alternatives

Which alternatives were evaluated?

Reasonable Alternatives

Which alternatives remain after the first round of evaluation?

Incorporating feedback from the community along with known constraints and challenges, the engineering team developed 17 alternatives called the “Preliminary Range of Alternatives” shown on this map. These 17 alternatives were evaluated using the criteria in the Alternatives Evaluation Criteria Matrix to determine the Reasonable Alternatives (shown below).

Potential Lane Configurations

What might the roadway look like?

The potential lane configurations for the improvements to US 278, or typical sections, include the options that are currently being explored. This also includes any potential multi-modal lanes such as bike or pedestrian paths.

Note: To view individual layers and zoom-in, please download files.

After evaluating the preliminary range of alternatives against the first set of criteria identified in the Alternatives Evaluation Criteria Matrix , 6 Reasonable Alternatives remain. Click “view” to see all these alternatives all together. (For a more advanced view or experience, download this file to view layers to toggle on and off each alternative). Or, view the PDFs for each of the alternatives individually below:

  • Build new eastbound Mackay Creek bridge south of the existing bridge

  • Recondition and widen existing westbound Mackay Creek bridge

  • Recondition and possibly widen Skull Creek bridges

  • Use existing alignment as much as possible

  • Build a new bridge to the north of existing westbound Mackay Creek bridge

  • Recondition existing westbound Mackay Creek bridge and convert to eastbound traffic

  • Use newly constructed bridge for westbound traffic over Mackay Creek

  • Recondition and possibly widen Skull Creek bridges

  • Build 2 new eastbound bridges south of the existing alignments, one over Mackay Creek and one over Skull Creek

  • Recondition and widen westbound Mackay Creek Bridge

  • Recondition existing Skull Creek Bridges and convert to westbound traffic only

  • Replace all 4 existing bridges with one new bridge immediately south of the existing alignment

  • Build a new access to the Pinckney Island National Wildlife Refuge and CC Haigh Jr. Boat Ramp

  • Use existing alignment east of the new bridges

  • Remove existing bridges

  • Build 2 new eastbound bridges just south of the existing

  • Recondition westbound bridges and widen in place

  • Improve access to the Pinckney Island National Wildlife Refuge and CC Haigh Jr. Boat Ramp

  • Utilize the existing transmission line easement for US 278 running from Jenkins Island through Spanish Wells Road

  • Replace all 4 existing bridges with one new bridge just south of the existing US 278 alignment

  • Build a new access to the Pinckney Island National Wildlife Refuge and CC Haigh Jr. Boat Ramp

  • Utilize the existing transmission line easement running from Jenkins Island through Spanish Wells Road

  • Remove existing bridges

Community Impacts

Throughout the summer and fall months of 2019, a Community Impact Assessment will be completed in the US 278 Corridor Improvements project study area. The Community Impact Assessment is a process used to analyze the impacts the project could have on nearby communities and their quality of life. The role of the Community Impact Assessment is to ensure the values of the human environment are heard and incorporated throughout the life of the project.

The assessment evaluates several issues of importance for each neighborhood, including neighborhood cohesion, safety, aesthetics, and mobility. To better understand potential impacts, information is being collected from the neighborhoods in the project study area through a variety of ways. In addition to surveys and comments, you may also see project team members locally in your neighborhoods or at stores in the area.

Community Impact Survey

How would this project potentially affect your community?

 
 

We would like to learn more about you and your neighborhood. Please help us understand more about your community by completing the survey above (or print and fill out the PDF below below). Your answers will help us better understand the concerns in your neighborhood and allow us to determine how the project may affect your community.

 

Highway Noise

Highway Traffic Noise - SCDOT

Communities are often concerned about the potential for increased noise after the completion of a road improvement project. SCDOT requires a noise analysis to be conducted as part of the standard project development process. Watch this video to better understand highway traffic noise and how it is evaluated. To read the SCDOT policy on Highway Traffic and Noise, click here.

Right-of-Way Acquisition

Right-of-Way Acquisition (SCDOT)

SCDOT roadway and bridge improvement projects are planned and developed through an extensive environmental review process, in accordance with the National Environmental Policy Act (NEPA). During this environmental review process, SCDOT performs environmental and community surveys and evaluates all the potential project alternatives that could be considered to meet the purpose and need of the highway improvements. SCDOT seeks to find the project alternative that strikes the best balance between meeting the needs of the highway and minimizing the impacts to the natural and human environments.

Community impacts, such as right-of-way impacts and property owner relocations, are considered as a part of the NEPA process. The public and potential impacted communities will be engaged throughout the NEPA process to gather input on the proposed project alternatives. Watch the video above to learn more about the Right-of-Way acquisition process. The SCDOT Right-of-Way portal can be found online here.
