Road Projects

SCDOT Dorchester Road Safety Improvement Project 

The South Carolina Department of Transportation (SCDOT) proposes to make corridor improvements to SC 642 Dorchester Road between S-373 (State Park Road) and S-259 (Parlor Dr).

A Road Safety Assessment (RSA) was previously conducted in partnership between SCDOT, Stantec, Town of Summerville, Summerville Police Department, Dorchester County, and FHWA. Safety improvements were identified, and the project team is in the process of developing a conceptual plan which may involve placement of a raised median, crosswalk and ADA improvements, and extend right turn lanes within the project corridor.

The purpose of this project is to improve safety and reduce congestion along SC 642 Dorchester Road.


Ridgeville Road (SC-27)

The Ridgeville Road (SC 27 N) widening and improvements project will consist of widening 0.94 miles of Ridgeville Road (SC 27 N) from two lanes to three lanes.

The project extends from US Highway 78, near the intersection of Kiser Lane to the Exit 187 interchange of I-26.


SCDOT Berlin Myers Parkway

The proposed work consists of the construction of approximately 3.25 miles of new roadway on new location between US 17A and SC 165 (East Carolina Avenue), referred to as Phase 3 of the Berlin Myers Parkway.

The design for the major portion of Phase 3 of Berlin Myers Parkway will consist of two travel lanes in each direction (12-foot wide outer lane and 12.5-foot wide inner lane), with curb and gutter.

BMP3 renderingThe project will also include a single point urban interchange (SPUI) at the intersection of Berlin Myers Parkway and East Carolina Avenue. The project includes the relocation of a portion of the Sawmill Branch Walk/ Bike Trail between East Carolina and Luden Drive. A new segment of trail would be constructed between Greenwave Boulevard and Luden Drive that connects to a sidewalk adjacent to the proposed roadway. 

Because the project is being proposed in a floodplain and in the vicinity of a Civil Works project, the proposed work also includes various floodplain mitigation efforts which directly impact the Sawmill Branch.

Traffic projections estimate this roadway will carry between 18,000 and 23,000 vehicles per day by 2030.
