PROJECT DESCRIPTION

PROJECT NEED

Due to existing traffic congestion and associated delays, the purpose of the proposed project is to improve traffic flow as well as reduce congestion and delays by constructing additional travel lanes. In addition, bicycles and pedestrians will be accommodated with better accessibility. Intersection improvements will be constructed at US 17A, SC 165 ( Bacons Bridge Road), and S-22 ( Orangeburg Road).

The table shown compares the 2004 Average Daily Traffic Counts (ADT) with the projected ADT for 2030. The ADT for 2030 includes the completion of other sales tax projects.
