South Carolina Roads - US 78/1/25/278

US 78, US 1/78, US 1/78/278, US 1/25/78/278


All of these routes SB/WB are about to cross the Savannah River into Georgia. The offramp to the right is closed for two reasons. Firstly, there is a ramp a little to the southeast, the last exit in SC, that serves the same function. Secondly, this ramp used to be US 1 SB, and now US 1 stays on the gigantic multiplex instead of briefly straying to the west before returning. In fact, back in the 1920s, that old offramp bridge carried both directions of US 1 and whatever other routes were around back then. You can see more photos of it via the "Old 1/25/78/278" link at bottom. First photo is courtesy Lou Corsaro.


US 25/SC 121 NB leave US 1/78/278 NB/EB, courtesy Lou Corsaro. Four US highways and five overall routes are far too many to keep together. Notice how the US 278 shield hovers a little farther away from the 1 and 78, near the right arrow - in another mile it indeed leaves to the right, though I'm not sure that was the intent.

And US 1 South.

Back in 2004, I-520, the Bobby Jones Expressway, ended just across the river on the east side of Augusta, GA. Since then, I-520 was continued back around to return to I-20, begging the question as to why it wasn't changed to an even-numbered Interstate for a loop.


On a more recent trip, Lou found a beautiful brand-new state-name shield (hint to other states: I like these) for the now-open highway.


For some reason, Lou's shield was replaced just a few years after it was installed, but at least the replacement is still state-named. I would note that the right lane also serves I-520 East, not just West, so the sign was right in the first place.
