It runs essentially from New Light Rd to US1 just east of Wake Forest, almost to Youngsville.
On the map, it's unimpressive, but it has about the richest share of curves and camber/elevation changes of any road in the area. It's got this one 1/2 mi stretch that includes a very hairy 3-curve complex with elevation dip and then into a short straightaway to a little crest in the road. You will leave the tarmac if you take the crest at about 75mph. It's straight on the backside too, so the landing is easy
