Inside South Carolina Department of Transportation

Project Prioritization

In 2007, the South Carolina General Assembly enacted Act 114. One of the landmark items in Act 114 was the requirement that the South Carolina Department of Transportation (SCDOT) Commission establish a priority list of projects to the extent permitted by federal laws or regulations, taking into consideration at least the following criteria: (a) financial viability, (b) public safety, (c) potential for economic development, (d) traffic volume and congestion, (e) truck traffic, (f) the pavement quality index, (g) environmental impact, (h) alternative transportation solutions, and (i) consistency with local land use plans. This requirement is now codified in Section 57-1-370(B)(8) of the Code of Laws of South Carolina, 1976, as amended.

The process has been referred to as the "Act 114 prioritization process," and the project lists generated by the process as the "Act 114 lists." Following the 2007 legislative session, SCDOT promulgated regulations to provide details regarding the establishment and implementation of the project prioritization process. The regulations were approved by the General Assembly in 2008 and are codified in South Carolina Code of Regulations 63-10.

In 2016, the South Carolina General Assembly enacted Act 275. Act 275 eliminated some Act 114 requirements but retained project prioritization. The requirement is still codified in Section 57-1-370(B)(8) of the South Carolina Code of Laws, 1976, as amended, and the process detailed in South Carolina Code of Regulations 63-10, as amended.

The Project Prioritization Process Directive explains the methodology used to establish project priority lists as reflected in the SCDOT Engineering Directives. Engineering Directives may be updated to reflect the latest methodology used to define priority projects consistent with state legislative requirements. The Project Prioritization Process Directive explains the types of projects included in SCDOT Program Categories, as well as the process for the development of prioritized lists by staff and their adoption by the SCDOT Commission.

Provided below is a summary of the program areas, the corresponding links to the priority project lists, and the applicable Engineering Directives. The provided lists are associated with projects proposed for inclusion in the 2017-2022 Statewide Transportation Improvement Program (STIP).

Safety - Includes eligible projects based on crash and fatality rates. Intersection projects may include turn lanes, horizontal realignments, roundabouts, and signalization. Section/Corridor Improvements may include paved shoulders, rumble strips, clear zone improvements and signing and marking upgrades. Interstate Safety Improvements may include high friction surface course, open graded friction course, and concrete grooving. Priority lists are updated annually or as funding is available to advance additional projects.
