This is an Interstate Road List document for Dorchester County, South Carolina, detailing mowing and vegetation management quantities for state highway maintenance operations. The document provides comprehensive specifications for routine maintenance services across Interstate 26 and Interstate 95, including shoulder mowing, median mowing, ditch vegetation management, and bridge vegetation maintenance. Total project quantities include 647.36 acres of mower work, 53,107 linear feet of weedeating on shoulders, and 70,614 linear feet of weedeating on medians, with an additional 123,721 total linear feet of barrier maintenance (guardrail and cable rail). The service area encompasses I-26 for 16.57 miles and I-95 for 16.04 miles, plus associated ramps totaling 14.92 miles.

The Interstate Road List represents a 2023 full inventory of maintenance requirements calculated using standardized measurements of 80 feet per shoulder and 80 feet per median across linear footage. A note indicates that guardrail quantities for I-26 were adjusted downward by 8,312 feet due to a construction zone at the Berkeley County line on the east side of a bridge. The document serves as the basis for establishing bid quantities and service specifications for the Traditional Mowing Dorchester contract opportunity in South Carolina, providing contractors with precise acreage and linear footage data necessary for accurate cost estimation and project planning.
