Planned Transportation Spending

South Carolina

An examination of South Carolina’s 2010-2015 Statewide Transportation Improvement Program* reveals that projects classified as “other” account for the largest chunk of planned spending (29 percent). This category includes Earmark funds, locally funded projects, and apportionment of highway infrastructure funds for unspecified projects. Road maintenance/minor widening projects follow, accounting for 25 percent of the STIP. New road capacity projects, identified by the state’s Department of Transportation as “construction,” comprise 22 percent of the planned spending, and bridge maintenance/replacement projects make up 12 percent. Safety projects make up 6 percent, transit projects 5 percent,** and bicycle/pedestrian projects account for 1 percent of the planned spending. The STIP’s Program Summary did not identify any bridge capacity expansion or road or bridge projects with bicycle/pedestrian components (such as adding sidewalks when reconstructing a roadway).

* TSTC used the STIP’s Program Summary to determine transportation spending across the state. The STIP does list individual district projects but these projects do not provide a complete view of statewide transportation spending as lump sum amounts for projects such as road maintenance safety improvement are not included.
** Transit total is from SCDOT’s Program Summary and may include state funds for operating assistance.
