SCDOT has decided that we must respond to the monetary demands of maintaining OGFC.
It appears that transitioning to SMA is our best option.
A special provision has been developed.
Currently looking for projects. Any volunteers?
Developing a framework for safety considerations. SMA will be the default surface type for interstate
construction. OGFC will not be totally eliminated.
