Highways That Cross Themselves

	Are there any? I remember seeing a diagram a LONG time ago in France (?) where a highways NB (fig.) lanes crossed over its SB (fig.) lanes (running on the 'American side'), then going back to the France's style. Anything...?

	US-131 (hidden I-296) crosses itself twice at the I-196 interchange in Grand Rapids, Michigan. Pictures and diagram: http://www.interstate-guide.com/i-296_mi.html I think that I-77 does the same in Charlotte, NC at the I-85 interchange. I must be getting old. I just went thru that interchange last week and I don't remember. Best regards Eric Chris Wilson wrote:> Are there any?

Anything...? Here is a list, which is as complete as I can remember right now: Interstate 8 switches sides at a mountain pass just east of Yuma, AZ. Interstate 5 switches sides at Castaic Pass, CA, roughly 45 miles north of downtown Los Angeles. Interstate 85 switches sides for roughly three miles in North Carolina (MP 99-102) because of the presence of a creek within the right-of-way. This is about 20 miles south of the "Death Valley" intersection near downtown Greensboro. Interstate 77 switches sides at its interchange with I-85, four miles north of downtown Charlotte, NC. Both Interstate 95 and its "child," I-695 (Baltimore Beltway) switch sides at their interchange several miles east of downtown Baltimore, MD. This allows for all eight possible movements to be accomplished with standard "diamond" ramps, saving a great deal of space over a diamond-cloverleaf configuration. Both Interstate 20/59 (going east-west) and Interstate 65 (north-south) switch sides at their interchange, commonly called "Malfunction Junction," in Birmingham, AL. US 131 switches sides at its interchange with Interstate 196 in downtown Grand Rapids, MI. The Grand River abuts the interchange, paralleling 131 and limiting the space available for the interchange. -- Larry Harvilla E-mail: roads AT phatpage DOT org also visit: http://www.phatpage.org/ Highways section in progress.

	I think I found a few of them to view: I-8 East of Yuma: http://www.terraserver-usa.com/image.aspx?T=1&S=12&Z=11&X=939&Y=4521&W=3 I-5 in California (pretty sure):http://www.terraserver-usa.com/image.aspx?T=1&S=12&Z=11&X=438&Y=4773&W=3 I-85 in North Carolina: http://www.terraserver-usa.com/image.aspx?T=1&S=14&Z=17&X=180&Y=1238&W=3 I-77 in North Carolina: http://www.terraserver-usa.com/image.aspx?T=4&S=11&Z=17&X=1285&Y=9758&W=3 I-20/59 and I-65 in Alabama: http://www.terraserver-usa.com/image.aspx?T=1&S=12&Z=16&X=645&Y=4636&W=3 I-196 and I-296 in Grand Rapids: http://www.terraserver-usa.com/image.aspx?T=1&S=11&Z=16&X=1519&Y=11896&W=3 IMHO, The I-77 interchange is the most intriguing. It almost appears that a standard cloverleaf would work as efficiently, but I don't work for North Carolina. Of course, the ramp from SB I-85 to SB I-77 would inevitably have to be redone into a sweeping ramp to accomodate traffic. Anyway, enjoy the views, have a blessed Sunday.

There is also an alternative that would retain the existing "crossover" interchange design, and add two semi-directional flyover ramps, from I-695 EB to I-95 NB, and from I-95 SB to I-695 EB.

Of course, the ramp from SB I-85 to SB I-77 would> inevitably have to be redone into a sweeping ramp to accomodate> traffic. Anyway, enjoy the views, have a blessed Sunday. The reason that I-77 is inverted is that the east-west "footprint" space available for the 77/85 interchange is limited. Less than half a mile east of I-77 sits I-85's interchange with Statesville Ave., which I figure must have already existed before I-77 was built in that area. A diamond-cloverleaf interchange or four-level stack with no side-swapping would require insanely long bridges to carry the ramps over Statesville Ave.. Even as it is, there is still some bridging of ramps -- the NB 85 off-ramp to Statesville Ave. and the SB 85 on-ramp from Statesville Ave. dip beneath some of the 77/85 ramps. As I mentioned up-thread, this configuration (where one freeway swaps sides and the other doesn't) is generally used when space around the interchange is constrained on only one side. Another example is the US 131/I-196 interchange in Grand Rapids, MI; since the Grand River sits immediately east of the interchange, 131 swaps sides to save space in an east-west direction. -- Larry Harvilla E-mail: roads AT phatpage DOT org also visit: http://www.phatpage.org/ Highways section in progress.

No, you're thinking of Tejon Pass, which is about 50 miles to the north of the place where I-5 swaps sides. If you're traveling north (e.g., L.A. to Sacramento), it is just north of Castaic (basically, the northernmost fringe of metro L.A.) where I-5 inverts to climb into the mountains. It is at Tejon Pass where you descend back down into the Central Valley, and where CA 99 breaks off of I-5. -- Larry Harvilla E-mail: roads AT phatpage DOT org also visit: http://www.phatpage.org/ Highways section in progress.

	Something that hasn't been mentioned: The 'pigtail' switchbacks on ALT US 16 near Keystone, SD. http://terraservice.net/image.aspx?T=1&S=10&Z=13&X=3127&Y=24295&W=3&qs=%7ckeystone%7cMissouri%7c http://terraservice.net/image.aspx?T=1&S=10&Z=13&X=3128&Y=24292&W=3&qs=%7ckeystone%7cMissouri%7c http://terraservice.net/image.aspx?T=1&S=10&Z=13&X=3127&Y=24288&W=3&qs=%7ckeystone%7cMissouri%7c (last one's tough to see, switch to topo for reference) I think there was only three. Anyway, Keystone - Custer St. Park is one of the coolest drives in the country IMO. Tunnels (most of which are one lane), switchbacks, pigtails, two lane divided segments... It's not a road, but I believe the trans-Canadian railroad does this same pigtail thing as it crosses the Continental Divide; in a tunnel, no less.

There are a few of these ("helices") on roads scattered around elsewhere: "12.14 Q: Do highways loop around themselves? A: Yes. This is called a "helix", and is used usually when a grade is steep enough that a direct route would be too impractical, occasionally at a tunnel entrance. It is commonly used on railroads. Regarding roads, some of the more famous helixes are on Newfound Gap Road (what would be US 441 if U.S. Highways were maintained within national parks) in the Great Smoky Mountains National Park, about 4 miles northwest of where it crosses the TN/NC border ( http://terraserver-usa.com/image.aspx?t=2&s=12&x=346&y=4932&z=17&w=2 , http://www.gsmnp.com/pages/newfound_gap2.html , http://smoky.com/content/view/27/37/ , http://www.smokymountainlodging.com/postcards/looproad.html ), three on US 16A in SD east of Mount Rushmore ( http://terraserver-usa.com/image.aspx?t=2&s=12&x=781&y=6073&z=13&w=2 ), on NJ 495 in Weehawken entering the Lincoln Tunnel into NY ( http://terraserver-usa.com/image.aspx?t=2&s=12&x=728&y=5641&z=18&w=2 ), and at the U.S. entrance to the Detroit [MI]-Windsor [ON] Tunnel ( http://terraserver-usa.com/image.aspx?t=2&s=12&x=415&y=5859&z=17&w=1 ).
