Most acute intersection?

[empirestate]

The intersection of Telegraph and Broadway in Oakland, CA struck me as being about as acute an angle as I've seen between two streets:

Any others out there with an even tighter angle? Extra credit if it's the intersection of two 2-way roads, but not required. Even more credit given if turns aren't restricted around the vertex, as they seem to be in the above example.

Disqualified if it's the junction of the opposing roadways of a dual-carriageway system (divided highway or one-way couplet). Also disqualified if the intersection or surrounding blocks have been significantly modified to reduce the acuteness for one or more approaches. (See for example, the nearby intersection of San Pablo and Market, where the alignment of southbound Market St. has been adjusted, so that the street no longer fits into its original ROW: https://goo.gl/maps/h8vcB)

Two 2-way roads:

NY 7 and US 20

Times Square.

The five corners in East Longmeadow, MA

Is there any way to measure the angle of these on Google Maps?

Hold a protractor up to your monitor?

NY 33 and Griswold Rd: http://goo.gl/maps/KvKsv

4 way, two way roads, no turn restrictions.

[hotdogPi]

NY 33 and Griswold Rd. is 21.76 degrees.

NY 7 and US 20 is 24.71 degrees.

Telegraph and Broadway is 33.39 degrees.

MA 220 and MA 186 is 22.65 degrees.



There seems to be a limit at around 20.


Sorry for the incorrect values earlier. I was using trigonometry.

The two that came to my mind quickly are:
PA 42 and PA 118:  http://goo.gl/maps/fcpFY
PA 29 at Pickering Dam Rd (SR 1017):  http://goo.gl/maps/2fbP8

PA 29 at Pickering Dam Rd (SR 1017):  http://goo.gl/maps/2fbP8

First one: 15.23 degrees. New record!

Second one doesn't qualify (if it's where I think you're talking about).

Northwest St & Exchage St / Castalia St, Bellevue, OH. Eyeballing it, I think it's about 20 degrees, if not slightly less.

Elmville Rd / Cow Run Rd, near Peebles, OH. Angle around 20 degrees, maybe slightly more?

Beech and Orange Streets in downtown Toledo...http://goo.gl/maps/j928R

Second one doesn't qualify (if it's where I think you're talking about).

The second one is in Chester County, PA, south of Phoenixville...it is two separate two-lane state roads...though turns are restricted.

The Blue Ridge Parkway and SR-664 near Lyndhurst, Va.

This probably doesn't win the prize for most acute, but it is the intersection of two major highways: U.S. 83 and U.S. 54 in Liberal, KS. http://goo.gl/maps/u0P7L.  What makes this turn (SB 83 to EB 54) even more difficult is the lack of a protected left cycle and heavy oncoming traffic on 83.

I had to make this turn a number of times, since for my work I would stay in Liberal and then go east of town via U.S. 54 to the power plant. Finally I learned how to avoid it using county roads.

I was thinking of Barcelona and the streets that run parallel to the coast and intersect the appropiately named Diagonal avenue, but the angle is a bit obtuse compared to some crossings posted there: 30 degrees approx.

a bit obtuse compared to... 30° approx

That's still acute though. You could say "less acute".

Sunnyside Avenue and Lincoln Way/Highway 30 in Missouri Valley Iowa is a VERY tight angle, and makes for a VERY awkward intersection.

Don't know for sure, but perhaps in the long long ago, Sunnyside was the original alignment of Lincoln Way?  But this would have been maybe 100 years ago, if then.

West Colfax at 6th Ave, Golden, Colorado. Not the most acute, but it is an acute intersection of two major roadways. http://goo.gl/maps/zCAgU

An issue with acute intersections is that they can lead to long pedestrian crossings.
(long pedestrian crossings thread: https://www.aaroads.com/forum/index.php?topic=5955.0).

Here's one of the longest crosswalk in America where two acute roads meet:

McCoy Rd. & Island Ave. (PA-51) in McKees Rocks has a turn restriction, but is two 2-way roads.

Times Square.

I calculate 13.5 degrees. Of course Broadway's been closed to motor vehicles since 2009, so it no longer counts.

If you're talking about Broadway and 7th Ave, Broadway bends at the intersection.

Seriously? You trust the Goog without even checking the aerial?
