The project consists of rocking approximately 17.3 miles of county-maintained dirt roads throughout Colleton County. It is comprised of 28 roadways. At each location, the road is to be fine-graded to ensure proper cross-slopes. Driveway and cross-line pipes are to be replaced as specified in the plans. Once the drainage has been improved, an approved rock base material (one that meets SCDOT spec) will be placed and compacted. Road widths and cross-slopes vary and are specified in the plans. Driveways will be rocked to the ROW line (50” ROW typical). The width of the driveway is to be 12’ unless the existing is with than match existing. Grass will be used on the shoulders of the roadway where the existing road is wider than the proposed rock surface, as noted. Utilities may be present along certain roads. The contractor will coordinate with the local utility providers and make the necessary relocations. All road work is to be performed within the existing right-of-way.
