No reassurance shield for any route as we turn and head under the railroad tracks. It’s up for debate as to whether or not this is actually a part of US 310- it definitely was at one point (it would also have been US 212), but at this point it’s not clear. It’s definitely a state maintained, primary highway though, so I don’t see what else it could be.

Adding to the belief that this is US 310, we’ll approach US 212 and I-90 (and not US 310) in a few blocks.
