In the Charleston area, most of the bridges are just referred to by their names (the Ravenel, the Westmoreland, the Don Holt). The Wando bridge is 526 over the Wando River in Mt. Pleasant.
I-26 is just referred to as 26. 52 (Rivers Ave) is just referred to as Rivers.
One we used to have was before the Ravenel Bridge was built, when it was two bridges going over the Cooper River. We had the “302 merge”, where I-26 and the Crosstown (US 17) split, going from 3 lanes to 2 lanes. That was a chokepoint during afternoon rush hour.
