I came across this cool article yesterday which goes into nice detail about the Queen City street grid:

https://slate.com/business/2018/07/manhattanhenge-exists-in-your-city-too.html

Does anyone know when Charlottehenge occurs at Trade and Tryon?

Since the uptown street grid is titled  southwest to northeast like Manhattan, I'm pretty sure it would occur in May and July like Manhattanhenge:

Make that the 2020 goal for this forum: Charlottehenge photos!

 

 

It looks like the sun angle and Charlotte's street orientation prohibits a "Charlottehenge," even at winter solstice:

Thanks!  Question: because the uptown street grid is tilted beyond 23.5 degrees from north-south, it prevents any type of Charlottehenge?

Yep. 

East Trade St. and its parallel streets have a heading of 136.3 degrees (measured from the north), but the sunrise azimuth only ranges from 60.0-118.3 degrees any day of the year.

South Tryon St. and its parallel streets have a heading of 229.7 degrees (measured from the north), but the sunset azimuth only ranges from 241.6-299.8 degrees any day of the year.

I see.  Any street grid must not exceed Earth's axial tilt of 23.5 degrees to achieve a 'henge.   Bummer for uptown CLT!

Any street grid at our latitude*. If Charlotte were moved further north, then we might hit it. Imagine if we were on the equator, then sunrise/sunset would be exactly east and exactly west twice a year.
