- The US 278 Corridor Improvements project runs along the US 278 corridor from Moss Creek Drive in Bluffton to Spanish Wells Road on Hilton Head Island. This project is to address structural deficiencies at the existing eastbound Mackay Creek bridge, increase capacity, and reduce congestion within the project limits
- The project is fully funded through a combination of funding sources to include the 2018 Penny Referendum, SCDOT and the State Infrastructure Bank (SIB).
- SCDOT is currently refining the design and preparing to present a preferred alternative to the public

Lady’s Island Corridor Traffic Improvements
- The 2018 Penny Referendum allocated $30 million for numerous projects along the US 21/SC 802 corridor to improve traffic
- Nine projects are included in the proposed corridor improvement and were developed as part of the 2017 Lady’s Island Corridor Study.
- A current update is provided for several of these projects in the 2021 Lady’s Island Traffic Study.
View Project Information for the Improvements
Airport Frontage Road
US 21 Airport Area and Frontage Road includes all improvements as shown in the study area of the map. These improvements would provide reduced travel delays and improved access management on US 21. They would also provide Little Creek Road and Lost Island Road access to the traffic signal.
Project Phase:
Design Team: Ward Edwards, Inc.
Estimated Project Budget: $4,980,000
Beaufort High School Access Realignment
Beaufort High School Access is located on US 21 (Sea Island Parkway) within a congested area consisting of multiple driveways and the nearby Sunset Blvd intersection. To improve operations, accessibility, and safety on US 21 (Sea Island Parkway), alternatives to relocate the Beaufort High School Access will be reviewed and would evaluate realignments to: Sunset Blvd at Sea Island Parkway, Hazel Farm Rd at Lady’s Island Dr, and improved access to Meridian Rd. The study area is shown on the map.
Project Phase:
Design Team: TBD
Estimated Project Budget: $1,792,000
Hazel Farm Road and Gay Drive
The Hazel Farm Road and Gay Drive (S-7-497) project would include paving of Hazel Farm Road, improvements to Gay Drive, construction of the roundabout, installation of new traffic signals at each end, and signal interconnection with the US 21 / SC 802 signal. Upgrading these roads would provide beneficial street connectivity, increased pedestrian and bike safety, and congestion relief for the main intersection.
With new signal implementation, this project is interdependent with improvements to mainline SC 802/US 21 Bus (Sea Island Parkway) and alignment of the new Lady’s Island Middle School Access project. Addition of turn lanes, realignment of the middle school access, and median work to provide access management is needed at the connection of Hazel Farm at SC 802 and Gay Drive at US 21 Bus (Sea Island Parkway) to provide the full benefit of the signal interconnection.
Project Phase:
Design Team: TBD
Estimated Project Budget: $2,984,000
Lady’s Island Middle School Access Road
The new Lady’s Island Middle School Access project includes realigning the main entrance road to the middle school with Gay Drive and tie-ins to the middle school driveways, existing Cougar Drive, and Robin Drive. Cougar Drive would become right in right out. The benefits of this configuration include safer access to US 21 and street connectivity with the surrounding neighborhood near Robin Drive. This project is dependent on improvements to the medians on mainline US 21 Bus (Sea Island Parkway) and signalization with the Gay Drive Project.
Project Phase:
Design Team: TBD
Estimated Project Budget: $1,483,000
Mayfair Court Extension
Extension of Mayfair Court to William Street involves a new roadway connection and is dependent upon coordination with property owners. The Mayfair Court Extension is warranted before or during improvements to SC 802 (Sam’s Point Road) are made, as a median will be installed on SC 802. The Mayfair Court Extension may be combined with the mainline improvements. This benefits roadway connectivity and traffic progression on mainline SC 802 (Sam’s Point Road).
Project Phase:
Design Team: TBD
Estimated Project Budget: $450,000
Meadowbrook Drive Extension
Extension of Meadowbrook Drive to Dow Road involves roadway work in existing right of way. The extension would increase roadway connectivity with access to the proposed signal at Gay Drive. This will be beneficial when Dow Road becomes right-in right-out. The Meadowbrook Drive Extension is not dependent on other projects, but its benefits would not be fully realized without US 21 Sea Island Parkway and Gay Drive improvements.
Project Phase:
Design Team: TBD
Estimated Project Budget: $776,500
Sam’s Point Turn Lane
This project includes the addition of the right turn lane at SC 802 (Sam’s Point Road) and US 21 Business. The dedicated right turn lane would open the existing right turn lane for conversion to a thru lane at the signal. This would benefit the intersection by providing relief for the heavy morning peak right turn movement and capacity for the through movement.
Construction will begin in January 2021.
Project Phase:
Design Team: Infrastructure Consulting & Engineering, PLLC
Contractor: APAC Atlantic
Estimated Project Budget: $761,000
Sunset Boulevard and Miller Drive West
Sunset Boulevard (S-7-186) and Miller Drive West (S-7-187) includes improvements to both streets, installation of a new traffic signal at the Miller Drive West intersection with SC 802 with signal interconnection with the US 21 / SC 802 signal. This would increase pedestrian safety on Sunset Boulevard and Miller Drive and provide congestion relief for the main US 21 / SC 801 intersection. These improvements are interdependent with the US 21 / SC 802 mainline project and the Beaufort High School Access Realignment.
Project Phase:
Design Team: TBD
Estimated Project Budget: $4,482,000
US 21 Business, US 21, and SC 802 Mainline Improvements
US 21 Business, US 21, and SC 802 Mainline includes all improvements to both corridors. The improvements include medians for access management, grass buffers and multi-use paths, lighting, and landscaping. These improvements would create a complete-streets feel to the corridor and benefits include enhancing bicycle and pedestrian accommodations, safety, and improved vehicular progression. The full benefit of this project is interdependent with completion of the other projects.
Project Phase:
Design Team: TBD
Estimated Project Budget: $10,776,000
Sidewalks and Multi-Use Pathways
- The 2018 Penny Referendum allocated $10 million to 24 multi-use pathways and County Council established 14 priority pathways.
- The County has selected Infrastructure Consulting & Engineering to perform design services for the 14 priority pathways.
- The County will seek additional funding in the form of state or federal grants, and public-private partnerships to build as many pathways and sidewalks.
