The partial cloverleaf interchange concept includes a new bridge constructed on new alignment for Calks Ferry Road parallel with the existing Calks Ferry Road overpass, which will be ultimately removed. A loop is proposed in the southwest interchange quadrant to facilitate free flow southbound (SB) traffic on Calks Ferry Road to eastbound (EB) I-20 toward Columbia. This is the heaviest movement in the morning peak hour. Calks Ferry Road is proposed to be widened to four lanes (two each way) prior to the ramp terminal intersections and remain four lanes within the new interchange limits. Ramp “A” is the I-20 westbound (WB) exit ramp to Calks Ferry Road which is located adjacent to Red Bank Creek and floodplain. It provides motorists options to turn onto northbound (NB) or SB Calks Ferry Road. Ramp “B” is the I-20 WB entrance ramp from Calks Ferry Road. Ramp "B" crosses the abandoned weigh station site which will be removed. Ramp “C” is the I-20 EB exit ramp to Calks Ferry Road. It provides motorists options to turn onto NB or SB Calks Ferry Road. Loop “C” is the I-20 EB entrance ramp from Calks Ferry Road which will be used by Calks Ferry SB traffic traveling toward Columbia using I-20. Ramp “D” is the I-20 EB entrance ramp from Calks Ferry Road, which will be used primarily by Calks Ferry Road NB traffic traveling toward Columbia using I-20.
