Before I updated this roundabout
The bubbles indicate a Keep Left (onto the bypass) and a Keep Right (to approach the roundabout)
The route also indicates that the segment after the Keep Right is called “SR57 - Main St”
Which is counter intuitive based on it still being part of Ryans Rd.
But it sort of makes sense as the people on Ryans Rd going to the roundabout are mostly going to exit onto Main St but not always.
[EDIT] Ryan St actually changes to Main St back at the previous bend. So that helps explain the naming.
