Thomas & Hutton was selected by Beaufort County to complete Phases II, III, and IV of the Bluffton Parkway. The roadway design standards were based on AASHTO and SCDOT requirements.
- Phase II, a 1.3-mile, 4-lane divided urban arterial with curb and gutter and pathways, included realignment of a 0.5-mile section of Simmonsville Road (5-lane) and intersection design at SC 46. Thomas & Hutton provided conceptual design, environmental studies, and wetland permitting assistance for a 6-mile segment of future phases. A signal at the Simmonsville Road intersection was designed and installed. The intersection designs were coordinated with SCDOT.
- Phases III, a 2.2-mile, 4-lane divided arterial roadway with curb and gutter and pathways on new location, included a large wetland crossing in which impacts were minimized by using a reduced median width. A pedestrian underpass was utilized to connect the pathways in a residential area.
- Phase IV, a 2.5-mile, 4-lane divided arterial roadway with curb and gutter and pathways on new location, included a dedicated pedestrian signal to allow walkers and bikers to safely cross. Significant improvements including widening and signal designs were coordinated with SCDOT on three intersection roadways. Five new signals were designed and installed as a part of the project. More than 14 miles of multi-use pathways were designed and constructed. The project was approximately $1 million under budget and was recognized by County Council as exemplary.
A total of five major intersection and signals were designed and constructed as a part of these projects.
