Hello, this route is actually signed as part of the VA 236 West route, despite it following a two-way road. If you're going west along 236/Main Street before the split, there is a sign directing 236 West traffic to make a right onto Blenheim Boulevard, and then along Blenheim, there is a reassurance sign with arrows directing traffic onto North Street, and eventually traffic is lead back to Main Street. It is confusing, but the pre-existing configuration before your changes was correct.
