NCSHP park their Chargers on this urban interchange next to the bridge railing, monitoring traffic on I-77. They normally are not here during rush hour as speeding isn’t an issue during those hours. The NCDOT weight inspectors also use the SB ramp as a monitoring position. They are not visible from I-77 until you see the blue lights. Posted limit is 55, traffic flow off peak is 60-70, so it’s a gift.
