I was surprised to see that NY Route 8 and 30 followed Old Route 8B well into the 1950s, if not the 1960s before the modern alignment. I would have thought such a twisty road with sharp, dangerous curves would have been re-aligned in much earlier on.

The original road was built in 1915, according to bridge inspection reports (click on blue box to pull up the report). Before then, people used Gilmantown Road past Gilmantown Lake to get from Wells to Speculator, with the portion of NY 8 along the East Branch heading south to Wells, until the 1935 bridge was built between NY 30 and NY 8 over the Sacandaga River.

The current alignment was built in 1968 it would appear, based on the fact that the Scandaga River Bridge in Speculator was constructed that year and that looking at historical topographic maps from the mid-1960s still shows the old alignment.
