How do you get to Business Loop 70 from Route B southbound in Columbia? This sign isn't entirely clear about the matter.
Here's how to decode it: turn right for westbound Business Loop 70. That's the easy part.
Go straight ahead for eastbound Business Loop 70, because, about a block after the bridge over the Business Loop, you'll be directed to turn left onto Ammonette Street, around the curve in the distance in this photograph. After another turn onto Old 63 (now a city street), you'll reach the intersection of Old 63 and Business Loop 70, and then you can turn right to go eastbound.
It's definitely not a straightforward intersection - just follow the arrows.
