To view basic Roadway Information please select a County, then either search by Street Name or by Route Type and Number. The map will highlight the road in different colors when the number of lanes or traffic volume changes.
Road Conditions include a map of all construction, maintenance, and hazardous weather events in which SCDOT is aware which may affect travel. These Road Conditions are on SCDOT maintained roads only. For non-state maintained road conditions please contact your local agency. Road conditions include all advisories ranging from full road closures to temporary shoulder closures. Please click on each event on the map for more information. To see Load Restricted Bridges, use the Show Search Options and then check the “Include Load Restricted Bridges”. The list of Load Restricted Bridges does not include any bridges maintained by Federal, County, or Municipal entities. Any bridge not restricted is open to state legal loads only. Loads above state legal loads require review and approval by SCDOT’s Oversize/Overweight(OSOW) office.
Did you know in South Carolina there are over 60,000 public road miles? SCDOT maintains over 41,000 miles of those roadways. The remaining miles are maintained by local governments, private businesses or individuals. The roads maintained by SCDOT are grouped into three categories: Interstates - Primaries (US & SC Routes) - Secondaries.
SCDOT, under FHWA (Federal Highway Administration) guidance, uses a unique numbering system to keep track of the roads in the state. Most people are familiar with the Interstate and Primary Numbering system. The Secondary numbering system carries the numerical number of the county followed by a unique number for that particular road. An example is S-40-100. This defines a secondary road in Richland County (40) with a road number of 100.
The SCDOT Commission may dedicate portions of a roadway or bridge after individuals or groups; however the actual road names are assigned by either county or city governments. SCDOT has recently started an initiative to partner with local governments to collect and produce a database of road names statewide. Through this effort, we are able to provide this website to the public as an additional navigational search tool. We currently estimate our database to have road names for over 90% of state maintained roads and 58% of local roads.
To use the tool, select the county name from the dropdown list and then type the name of the road. Should your search deliver a "No records found" result, we do provide a number for our local SCDOT office to assist you with your search.
