About this file
This file is an Engineering Directive (ED-16) issued by the South Carolina Department of Transportation (SCDOT) effective March 30, 2009, establishing standards for the installation and maintenance of driveway entrances to state highways. The directive applies to residential driveway construction and specifies that SCDOT shall construct driveway entrances and aprons within the right-of-way at no cost to property owners, provided the driveways serve existing or newly developed property for personal use and do not create hazardous conditions. Residential driveways are limited to a maximum width of 16 feet for the paved portion. If drainage pipe culverts are required, SCDOT will install up to a 30-inch diameter pipe; homeowners must bear any additional costs for larger diameter pipes. Driveway construction shall include base and surfacing to provide all-weather access. Wider or additional entrances may be constructed at the owner's expense with approval. The district engineering administrator may authorize driveway installation at SCDOT expense when an existing driveway is present and the property's land use has changed significantly.
Driveway construction requirements mandate that pipe culverts be selected and installed according to Engineering Directive 24, with minimum pipe diameters of 12 inches. Driveways must incorporate a 2-foot-wide shoulder at a 4:1 slope with no greater than 3:1 slope for the remainder of the front slope; shoulders and slopes shall be grassed to prevent erosion. Surfacing must be all-weather capable, utilizing either asphalt (minimum 2 inches thick with a compacted 6-inch base) or concrete constructed per SCDOT 2007 Standard Specifications. Driveway alignment, approach grade, and radii must comply with SCDOT Access and Roadside Management Standards (ARMS). SCDOT is responsible for maintaining residential and commercial driveway entrances within the right-of-way and shall address hazardous conditions within roadway shoulders, including sideline pipe.

Purpose: Provide Direction for Installation of Driveway Entrances
This Directive Applies To: Maintenance
INSTALLATION OF RESIDENTIAL ENTRANCES
The South Carolina Department of Transportation (SCDOT) shall construct, at its expense, the portion within the right-of-way of entrances and aprons to state highways at any point necessary to render adequate ingress and egress to the abutting property at locations where the driveways will not constitute hazardous conditions. The driveway must be of access to existing developed property or property that is being developed for the personal use of the owner and not for speculative or resale purposes. The driveway shall be a maximum of 16 feet wide (paved portion). If pipe culvert is necessary for drainage, SCDOT shall install the amount necessary, up to 30-inch pipe. Should driveway installation require pipe larger than 30 inches, the
Department may install the pipe and charge the homeowner for the difference in cost between
30-inch pipe and the larger diameter pipe required. Driveways requiring drainage structures other than pipe must be brought to the attention of the Director of Maintenance. Entrances to be constructed as outlined in this section shall include base and surfacing as necessary to provide all-weather driveway entrances. If wider entrances or additional entrances are requested and approved, construction may be performed by the Department at the owner's expense. The district engineering administrator is authorized to approve installation of a residential driveway at
SCDOT expense when a present driveway exists, if the land use of the property has changed significantly.
DRIVEWAY MAINTENANCE
Maintenance of residential and commercial driveway entrances within the right-of-way may be performed by the SCDOT as deemed necessary. The Department shall address any hazardous conditions that may exist within the limits of the roadway shoulder, including the sideline pipe.
Engineering Directive 16
DRIVEWAY CONSTRUCTION
Pipe culvert should be selected according to Engineering Directive 24 (ED-24). Pipe culvert shall be placed and backfill compacted according to ED-24. Pipe diameters less than 12 inches are not permitted. The pipe culvert should, where possible, be placed in the center of the ditch and fit the alignment and slope of the ditch. Pipe shall be of a sufficient length to extend to the toe of the backfilled slope. Driveways should have a 2-foot wide shoulder at a 4:1 slope and shall have no greater than a 3:1 slope for the remainder of the driveway's front slope. The shoulder and slope shall be grassed to prevent erosion. The surface should be an all-weather concrete or asphalt surface. Asphalt surfacing should be a minimum of 2 inches thick with a compacted 6-inch base. If the concrete option is used, concrete driveways should be constructed in accordance with the SCDOT 2007 Standard Specifications for Highway
Construction. The driveway's alignment with the existing road, approach grade, and radii should be constructed in accordance with SCDOT Access and Roadside Management
Standards (ARMS), latest edition.
