Traffic circles on US6 in NY

Wiki claims that US route 6 has three traffic circles in.New York, more than any other route. Can someone tell me where any of them are?

The Wiki page lists them:

They’re all within a mile or so of the Hudson. Long Mountain Circle about a mile west, Bear Mountain Circle on the west shore, and the Rte. 6/Rte. 9 junction on the east shore.

That’s all in the article, by the way.
