Substantially Completed on December 14, 2017

The Delemar Highway widening and improvement project consisted of widening 2.3 miles of Delemar Highway (SC 165) from two lanes to five lanes.

The project area extended from Ashley Ridge High School to Carolinian Drive in unincorporated Dorchester County.

In order to improve safety, provide for alternative transportation modes along this corridor, and increase capacity, the following improvements have been made:

Construction of two 12’ through travel lanes in each direction and a 15’ (typ.) center median between the travel lanes to accommodate turning traffic;

Construction of auxiliary turning lanes; construct 4’ wide dedicated, marked bicycle lanes in each direction; construct a 8’ wide sidewalk to provide pedestrian access for Ashley Ridge High School;

6’ wide grassed shoulders constructed for safety and emergency access; drainage improvements will include replacement of existing pipe culverts and driveway pipes, and construction of ditches;

And an existing double 8’ x 5’ box culvert extended 10 feet in order to accommodate the widened roadway.


Funding

The project was funded through:

  • $17 Million grant from the South Carolina State Transportation Infrastructure Bank
  • $1.505 Million in Dorchester County Capitol Funds
  • $1, 095,000 in CTC Funds
