Road Design and Highway Design Manual

2009 Revisions are now available.

The Mission of the Roadway Design Support Office is to provide context sensitive expertise, assistance, and guidance to assure that the design of roadways and related infrastructure is soundly engineered to be safe, aesthetic, and usable by all modes of travel (pedestrians, bicyclists and motorists) by utilizing the values of professionalism, diligence, honesty, and a continually growing reservoir of individual and collective experience and knowledge.

The South Carolina Highway Design Manual has been developed to provide uniform design practices for Department and consultant personnel preparing contract plans for Department projects. The designer should attempt to meet all criteria and practices presented in the Manual, while fulfilling the Departments operational and safety requirements. However, the Manual should not be considered a standard that must be met regardless of impacts. Designs will generally be made to values as high as are commensurate with conditions. Values approaching the minimums herein will be used only where the use of higher values will result in unacceptable effects on the economic, environmental, aesthetics, social and/or cultural resources of an area.

The Manual presents most of the information normally required in the design of a roadway project; however, it is impossible to address every situation that the designer will encounter. Therefore, designers must exercise good judgment on individual projects and, frequently, they must be innovative in their approach to roadway design. This may require, for example, additional research into highway literature.

A SCDOT task force under the direction of the Road Design Section developed the SCDOT Highway Design Manual with assistance from the engineering consultant firm of Roy Jorgensen Associates, Inc. and their subconsultant, the LPA Group, Inc.
