I'm looking for examples where braided ramps have been used in very tight (narrow) R/W. Here's one example in Arizona:
https://goo.gl/maps/qSEi5noSmfG2
More please!
Here's an example along the 405 in Bellevue, WA. There are several more along 405, but no good images nor any decent satellite imagery (out of date).

A somewhat tight one for WB I-74 in downtown Peoria, IL: Aerial (https://www.google.com/maps/@40.6934006,-89.5852627,412m/data=!3m1!1e3?hl=en)

I-190 Exit 9 in Buffalo (https://www.google.com/maps/@42.8998207,-78.8981667,390m/data=!3m1!1e3). This one has since become more complex with the addition of a slip ramp connecting the entrance ramp with the exit ramp.
This is quite common for MDOT.

I-435's southern leg in Kansas has a lot of new braided ramps between mile markers 79 and 83.

California 170 at Victory Boulevard in North Hollywood.
Aren't there new braided ramps along I-405 where it meets Sunset Boulevard and Wilshire Boulevard?
Two examples from the East Coast:

Here is part of many on I-4 near Disney. This aerial shows two braided ramp examples on both sides of the interstate. Both are between Exits 65 and 67 where travel between both interchanges is not possible.
Thanks everyone! It'd be tough to find any much "tighter" than the example Will gave; that's a lot of square footage for one lane over two!

I'm also interested in service interchanges next to system interchanges, so I thought Brandon's Grand Rapids example was really interesting.

Tightest ramp braid in Wisconsin is between Highland Ave and Fond du Lac Ave on I-43:
(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fi113.photobucket.com%2Falbums%2Fn208%2Ftriplemultiplex%2FAround%2520Town%2Ffdl%2520av_zpshtmmrtd8.jpg&hash=90bdf42193650504a776948ae599d53513f6c711)
Tight enough and acute enough to need those support columns that straddle the lower ramp.
Tightest in New York is probably this one on the BQE at the Northern Boulevard SPUI (https://www.google.com/maps/@40.7549731,-73.8987474,3a,75y,326.17h,82.62t/data=!3m6!1e1!3m4!1sOlDHXTzHBooasCtsrFVFjg!2e0!7i13312!8i6656). This one on the Cross Westchester (https://www.google.com/maps/@41.0326078,-73.7509123,611m/data=!3m1!1e3) is relatively tight. I can't immediately think of any others in this state - system predates braided ramps by several decades in places. I'm not counting the ramp from the Sag to the LIE that crosses the service road.
Gardiner Expwy in Toronto (https://www.google.ca/maps/@43.6444831,-79.3740079,799m/data=!3m1!1e3?hl=en&hl=en)
WB Gardiner to NB Yonge St braids with SB Jarvis St to WB Gardiner, while NB Bay St to EB Gardiner braids with the EB offramp to Jarvis.
Preeeeeetty tight, especially on the south side.
Didn't see this one posted:

Pretty sure the ramps to get off at Chinatown on I-55 and I-90/94 have braided ramps.
I don't think anybody's yet mentioned the brand new ramps along the US-31 freeway near 106th St. in Carmel, IN: https://www.google.com/maps/@39.9372272,-86.1613806,16z (https://www.google.com/maps/@39.9372272,-86.1613806,16z). They are quite tight, but there's no imagery to show yet.

I think I've only seen the braided loop ramps at a handful of locations; thanks for sharing! I've wondered why this isn't done more often; sure it's lower speed than a semi-directional or directional ramp, but it's got to be way cheaper too!
Both ends of the West Dodge Expressway in Omaha.
East end is 'better'.

Skipped over it. Not really a braid because Exit 3/3B is completely elevated over Exit 3A/4. The latter's ramps are entirely before/after the former's.

Yeah, it was a big deal when that interchange in Chesapeake was rebuilt. The design actually won an innovative management award (https://americastransportationawards.org/past-projects/2010-2/va-battlefield-boulevard-chesapeake-project/) in the 2010 edition of the America's Transportation Awards, in part because of the use of braided ramps.
There's a really good aerial shot of the braided ramps in that article:
(https://americastransportationawards.files.wordpress.com/2013/02/va-battlefield_project.jpg)
Found a construction pic of the west end.
Kinda sexy from this angle :)

There is one at Universal (the exit ramp for Sand Lake Rd goes over the entrance from Universal Studios)
