Perfect 3-way intersection

[hotdogPi]

I want to know if there are any 3-way intersections that are evenly spaced, 120 degrees apart. If you can't find a perfect one, you can find near-perfect ones, like the one below.



Major roads preferred. This is the northern end of the concurrency of US 2 and US 3.

This is what instantly came to my mind.  Not a perfect 120 degrees but it shows how this type of intersection may be a perfect candidate for a roundabout (with slip lanes).

Not perfect, but I can't pass up Zanesville's Y-Bridge.

Not major streets, or even that perfect, but the intersection of California & Benton avenues in the Brighton Heights neighborhood of Pittsburgh's Northside is enough of a "Y" that all approaches are allowed (with some hour restrictions) to Right Turn On Red.

What came to my mind was OH 28 and OH 771 in Leesburg.  This appears to be the center of the town plan. However, it's actually a 4-way intersection, with angles of about 120, 120, 60 and 60.

What I find annoying is that at this type of intersection, sometimes the double arrow sign is mis-used for the direction of traffic that does not have the stop sign.

Here is an example in Argyle, Texas: https://maps.google.com/?ll=33.079835,-97.158848&spn=0.000004,0.003098&t=h&z=19&layer=c&cbll=33.07987,-97.158717&panoid=HNMB1Z3pI5aoIe_x-sInBA&cbp=12,256.05,,0,0

The intersection of Knowlton Road and Manchester Avenue in Media, PA has this.

US 20A, NY 16, and NY 78 in East Aurora, NY comes pretty close: https://goo.gl/maps/YOhJI

This is sort of stretching it, but US 4 and NY 254 in Hudson Falls, NY have village square exits in a triangular pattern. Not quite 120 on the north side, but resembles the shape: https://goo.gl/maps/IpdnO .  Not too far from here in Glens Falls, there was an intersection with NY 9L and NY 32 branching off of the east side of US 9, with angles between each highway of 60 degrees and US 9 continuing straight. This oddity was broken when a road was built on the west side.

Though not a perfect 120, we have a pretty unique 3-way here in the middle of Greensboro, VT at East St/Wilson St/Breezy Ave. (what the Goog lists as "E Craftsbury Rd" is actually Wilson St for about 1/3 mile)

Thread bump...

My internship involves going through different intersections on Google Street View and filling a database. After over 10,000, the first true perfect 3-way intersection is in Scituate, MA, where Stockbridge Rd. meets Driftway. Bing Maps has imagery, but Google Maps does not.

It's not a road, but it's a notable attraction in Midland, MI, and a perfect 3-way intersection:

As soon as I saw the reference to Midland I knew exactly what you were talking about.
