braided exits

[agentsteel53]

or, where the exit A comes before exit B - but the destination B is before the destination A.

two examples in San Diego - one involving another freeway, the other two surface streets.

8 eastbound - the 125 interchange is huge and begins before the La Mesa Blvd ramp, even though 125 itself is just past it.

163 southbound - the University Ave exit comes before the Washington Street exit, but University itself is one block south of Washington.  (took me a while to figure out that neighborhood and part of the problem with my intuition was the exit braiding!)

I-696 westbound.  Ryan Road exit is signed with VanDyke.  Then the Mound Road exit.  Then you finally get to Ryan Road - but there's no exit there because the Mound entrance is too close.

I-285 northbound on the northeast side of Atlanta - in order:

- Exit 33 ramp to I-85
- Exit 34 ramp to Chamblee-Tucker Rd
- Chamblee-Tucker overpass
- Entrance ramp from Chamblee-Tucker
- Exit 32 ramp to US 23/Buford Hwy
- I-85 overpasses
- Entrance ramps from I-85
- Buford Hwy overpass

I hate how California always numbers ramps in order, even if it leads to different exit numbers in each direction.

A Connecticut example:

from http://www.alpsroads.net/roads/ct/i-84/w1.html

[TheStranger]

Heading northbound on 101 in San Jose, the ramps for the 280/680 junction begin south of the Story Road cloverleaf, even though 280/680 are about a quarter mile north of Story.

Much further north, at the second 101/280 junction in San Francisco, the ramp for 280 north from 101 north begins a quarter mile south of the Silver Avenue exit (which feeds onto Bayshore Boulevard/old Bypass US 101), though 280 is a quarter mile north of Silver.

At I-238's west terminus with the Nimitz Freeway in Hayward, the ramp for 880 south splits off westbound 238 about 1000 feet before the ramp for Hesperian Boulevard; 880 is a quarter mile west of Hesperian.

In the San Fernando Valley, the ramp from I-5 north to Route 118 splits off before the ramp for Paxton Street (which I-5 north crosses first).

EDIT: Another one in California, this time in Orange County: westbound 91 at Route 241 has the ramp for 241 south splitting off east of the ramp for the closer Gypsum Canyon Road.

I'm not sure I would ever notice.

California isn't too good at exit numbers.

[agentsteel53]

it looks like the majority of braided exits are because a freeway-to-freeway connection requires a much larger footprint.

any examples where both halves of the braid are freeways?  or, like Washington and University, where neither are? 

I think the Washington and University example is due to mountainous terrain.  it looks like it's easiest to place the University off-ramp through a valley that Washington bridges than any other possibility.  (also: because 1948.)

Featured on the Columbus meet: Exit 32 of I-270 is between Exits 33 and 30. 33 and 30 are on the same C-D road, and 32 is on the mainline with no C-D access, so the NB mainline goes 30/33 - 32 and the SB goes 33/30 - 32.

Cross County Parkway, NY: Heading eastbound, the 4S/5/6/7 C-D road exits before Exit 4N, which loops off the mainline.

[mass_citizen]

does US 1 @ I-95 in Peabody, MA count?

I usually here the term braided exits as referring to something slightly different, where the exit ramps are in the correct order, and the entrance ramps are in the correct order, but the second exit ramp comes before the first entrance ramp (sometimes with a slip ramp for entering traffic to use the next exit, sometimes not).

Then there's the ISTHA.  For them, Ogden Avenue off I-355 gets two exit numbers due to the I-88 exits.  ISTHA seems to believe that an exit number should be based off where the crossroad crosses the tollway.  In this case, Ogden crosses at MP19, I-88 crosses at MP20.  However, the exit for Ogden for northbound I-355 is after the exit for I-88.  Thus, we get I-88 as Exit 20A northbound followed by Ogden at Exit 20B.  Yet, southbound, Ogden is Exit 19.

I'm not sure I'm understanding the question correctly, but from how I read it, I think the ramps built in the past few years on southbound Telegraph Road (VA-241/611) in Fairfax County just south of I-495 may qualify.

Background: For years if you were coming south on Telegraph you passed under the Beltway and the left turns at the first and second traffic lights were for Huntington Avenue and North Kings Highway, respectively. The first light was a semi-crossroads at which the leg on the west was one-way, a ramp coming off I-495. Traffic exiting I-495 and bound for Kings Highway had to make a right at that light and an immediate left at the next light.

A 1980 aerial view may be found here: http://www.historicaerials.com/aerials.php?scale=8E-06&lat=38.7982655637803&lon=-77.0799459329524&year=1980   By 2002, not a lot had changed: http://www.historicaerials.com/aerials.php?scale=8E-06&lat=38.7982655637803&lon=-77.0799459329524&year=2002

In those two views, the Huntington Avenue intersection is the first one below of the waterway that cuts across the image and Kings Highway is the next one below that.

As part of the Woodrow Wilson Bridge replacement project, Telegraph Road was rebuilt in a way that reduces the amount of red time you face at the lights through there. Traffic exiting I-495 now flies over Telegraph to both Huntington Avenue and Kings Highway. In conjunction with that, southbound Telegraph traffic now has exit ramps. In the Google Maps view below, I've left the map oriented the same way as the Historic Aerials photos for easier comparison, but you might be able to see the ramps better if you rotate it 180°. With the new ramps, you turn right instead of left, and the first ramp on the right leads to Kings Highway while the second one (an elongated loop-around) takes you to Huntington Avenue. Thus, the first ramp goes to the second destination and the second ramp goes to the first destination.

This configuration opened in 2011 [edited to add: the loop ramp to Huntington Avenue opened in May 2009!] but it seems like it still confuses the crap out of a lot of people. Every time I go through there, somebody makes a U-turn at the light south of Kings Highway and then a right onto Kings; alternatively, some people drive through the car park seen at the bottom of the images (it serves a Latin American supermarket and it's not the safest one to use as a thru route due to the truck unloading dock being at the FRONT of the store as you enter the car park). I presume some of these people must be following outdated sat-nav directions, but the number of people doing it is high enough that I think some of them have to be drivers who are just plain stupid and don't read signs/watch where they're going. The police wrote hundreds of tickets in the days after the new ramps opened due to people who persisted in illegally turning left via the old routes, and there were a lot of media complaints that it was confusing to have the Kings Highway ramp come before the Huntington Avenue ramp when Huntington Avenue is the first street. (I still don't understand how it's confusing when there is a green sign telling you where the ramp goes....) I remember seeing a picture of a cop who had a Metrobus pulled over!

Here is the current layout:

[Per my edit above: Anyone who uses that road regularly and still hasn't figured out the Huntington Avenue ramp almost five years after it opened is not qualified to hold a driver's license.]

Then there's the ISTHA.  For them, Ogden Avenue off I-355 gets two exit numbers due to the I-88 exits.  ISTHA seems to believe that an exit number should be based off where the crossroad crosses the tollway.

Makes perfect sense.

In this case, Ogden crosses at MP19, I-88 crosses at MP20.  However, the exit for Ogden for northbound I-355 is after the exit for I-88.  Thus, we get I-88 as Exit 20A northbound followed by Ogden at Exit 20B.  Yet, southbound, Ogden is Exit 19.

So they don't number northbound based on where Ogden crosses.

Going westbound on I-80 in Omaha at I-680.  Exit 445, which is for West Center Road and I, L (US 275/NE 92) and Q Streets, comes before Exit 446 (I-680).

Nope, and I believe it is so that the exit numbers are in order.  I did not get a photograph fast enough, but the original signage (gore sign only) for Ogden was Exit 19 northbound.  It was removed quickly and replaced with the Exit 20B signage.

Would MA 128/I-95/MA 30/Mass Pike qualify?

[vdeane]

ON 400/ON 407/Steeles Ave (maybe including RR 7 as well)

[sammi]

ON 400/ON 407/Steeles Ave (maybe including RR 7 as well)

Steeles is ~500 m south of the 407, but the 407 exit comes ~250 m before Steeles. Highway 7 exit is past Steeles still, it's around the point the 400 goes over the 407.

Thanks Sammi! Your link worked just fine for me. That looks like a nice mess of spaghetti at first! Wow!

In Anne Arundel County, Maryland, on westbound U.S. 50/southbound U.S. 301 (John Hanson Highway, also "secret" I-595), Exit 21 (for northbound I-97 toward Baltimore) comes before Exit 22 (for eastbound Md. 665 (Aris Allen Boulevard)) even though the mileposts and exits "count down" toward the District of Columbia border.

SB Florida's Turnpike the A comes before the B in Ocoee, FL.  You have Exit 267A for SR 429 in BOTH directions and 267B for FL 50 in both directions.  The original Exit 267(now 267B) trumpet has always been in its spot since the road opened several decades ago.  When the FL 429 was added it used flyovers that take off before the original Exit 267 on either side so it works out.

FL 429 crosses the Turnpike proper just north of the 267 trumpet.

Here's an interesting configuration at a service interchange that I don't recall seeing before:
