While I was looking around in Middlebury, I noticed that the signage on the ground for VT 125 and the HB don't exactly match up. The signage according to Google seems to have VT 125 in a brief concurrency with VT 30 to US 7, then starting the concurrency with US 7 at the VT 30 junction instead of the connector further south. However, Google also had all the VT shields in the VT 125/US 7 concurrency posted as "TO" VT 125, so I don't know what to make of that.
Apologies if this came up in the old forum.
