Pretty sure. I have to admit, I thought this was a red maple until I got home and looked at my pictures. Now I feel quite certain that it is a sugar maple (Acer saccharum).
The Sugar Maple is a landscape standout. Medium to dark-green leaves turn yellow, burnt orange or red in fall. Tolerates shade, likes a well-drained, moderately moist, fertile soil. Do not plant in confined areas or where salt is a problem. Grows to 60′ to 75′.
I found this article which helps to sort things out: “Red versus Sugar.” The existence of the piece indicates that confusion is common, but if you have a different opinion let me know. The article’s illustration shows clearly how the leaves differ.
The leaf margins tell the main story: sugar maples have smooth edges while red maples are toothed or serrated.
At any rate, the tree on Blackstone Boulevard at Rochambeau was causing something of a sensation today. I was one of three people taking pictures.

It is easier to see the margins of the green leaves actually. The picture does not do justice to the colors.
