Title: Let's see some braided ramp examples
Post by: johndoe on May 11, 2016, 09:15:01 PM
I'm looking for examples where braided ramps have been used in very tight (narrow) R/W.  Here's one example in Arizona:

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 There are several more along 405, but no good images nor any decent satellite imagery (out of date).

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.

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.

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!

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:
