Notable incomplete interchanges

[Bickendan]

Here's an odd one I found: http://www.openstreetmap.org/#map=15/50.6471/-119.9520&layers=Q
The missing movement is the sb BC 1 to sb BC 97.

There are numerous example of interchanges with missing movements, so exclude ones where the mainline angles preclude a couple movements (the El Toro Y, CA 170 at I-5 and I-405 in Los Angeles itself are three that fall here). Also exclude examples where a construction project was cancelled (the I-5 to/from the N Kirby Ave ramps on the Fremont Stack in Portland; the I-35W/335 interchange in Minneapolis) and examples where ramps were removed (Steel Bridge to I-84/US 30 in Portland).

Do include though partial interchanges where a ghost ramp is present, for example, the SE Water Ave ramp from nb I-5 (now part of the I-84 ramp) has a ghost ramp on the sb side for a planned-never built-now dead proposal to connect the Inner SE Industrial District to sb I-5.

(No doubt a similar thread has existed before)

The junction of Route 4 and I-80 in Hercules, CA is basically a three-level stack with no ramp from I-80 east to the westbound stub of Route 4 (as this movement is handled by an auxiliary ramp to Willow Avenue) and no ramp from I-80 west to Route 4 east (which requires an indirect surface street connection to the north).

Further east on Route 4 in Antioch, the junction with Route 160 currently lacks a ramp from westbound Route 4 to northbound Route 160, and a ramp from Route 160 south to Route 4 east.  (Until the construction of the Brentwood bypass a few years ago, Route 4 used to continue a mile north along 160 to Main Street)

Do the infamous stub ramps from the Hartford Beltway (I-291)'s cancellation count?

[ekt8750]

NJ 42 NB to I-295 SB. Thankfully that's eventually going to get corrected but that interchange bugs me to no extent.

If you're talking about ghost ramps the I-95/Betsy Ross Bridge/Aramingo Av Interchange is a classic one. The overpass that was supposed to carry the never-built Pulaski Expressway from the Betsy was never completed but the ramps to nowhere still exist.

San Angelo, TX

Traffic on WB US-87/Loop-306 has no direct connection to SB US-277.  Instead, it is expected to use the Loop-378 exit by way of one stoplight and two stop signs.  Personally, I'd just squeeze a loop ramp in the middle there.

Breezewood.

Should have excluded full Breezewoods. Too obvious.

I-495 and I-66 in Virginia. There's no access from westbound I-66 to northbound I-495 or from southbound I-495 to eastbound I-66. In both cases, the Dulles Access Road Extension three miles to the east/four miles to the north provides the missing moves; Route 7 (an arterial street) can also do the same. (For that matter, you can't go from the Dulles road to westbound I-66 or from eastbound I-66 to the Dulles road, again because I-495 provides the necessary connection.)

http://www.google.com/maps/@38.904733,-77.1953727,14z   <----on my screen this is zoomed so you can see I-495, I-66, and the Dulles Access Road Extension, but a smaller display might require scrolling the map.


Near Montreal, access to the Pont Victoria from Autoroute 20 is incomplete: It's easy to reach the bridge from the southbound side, but from the northbound side you either have to exit in advance and go through the streets or go past it and turn around. Last time I was through there, there was no sign advising you how to reach the bridge, either; I assume they want people to use the Pont Champlain to the south.

I assume this thread is supposed to revolve around missing movements that should be there versus missing movements that serve no purpose (such as BC interchange in OP).

So, without further ado, the most annoying interchange in Seattle (IMO):



EB 18 cannot go south on 167 and NB 167 cannot go west on 18. If you're one of the many at the Outlet Centre nearby, this particular annoyance is...uh, very annoying. You can take Peasley Canyon Road nearby, but besides the roundabouts halfway up the hill, the signals at the top are killer and taking the freeway the whole way is much faster.

The Edens/Kennedy Junction in Chicago (I-90/94's northern split) can be annoying at times. The SEB->NB and SB->NWB movements aren't there, which basically shoves all O'Hare-to-Evanston traffic onto surface streets. It's not a terribly important movement, but it would cut down on travel times for Northwestern students and residents of Evanston, Skokie, and the far North Side (Edgewater, Rogers Park, etc).

I-805's Exit 11 in San Diego, is basically a glorified offramp to 43rd St. It was to be part of unconstructed CA 252.

You can connect via West Valley Hwy and 15th Street; Presley Canyon Road has nothing to do with it.

(That said, I agree that it's a pain and a half anyway.)

-The aforementioned Hartford interchanges, notably the full stack on I-84.
-The never-used Korean War Veterans Parkway interchange on the Staten Island Expressway (while it still existed)
-2 interchanges on NY 440
-Eastern end of the LIE
-I-77 at Ohio SR 21 north of Akron
-The LIE at the Van Wyck in Queens- no moves to/from the east, forcing traffic to use surface streets
-I-81 at I-690 in Syracuse - no moves between the north and west

[Beeper1]

I-95 and I-395 in CT.  No SB to NB movements.

[Sam]

NY 104/NY 590: no west-to-north or south-to-east movements.

I-84 and I-91 in Hartford.  Have to use CT 15 for I-91 N/ I-84 E and I-84 W/ I-91 S movements.  And then there was the pre-1989 I-84 E/ I-91 N nightmare.

You say "have to" like it's a bad thing. I-91 N to I-84 E existed.  It was terrible and harrowing, practically a hard right turn off the Interstate.  The current situation is a "complete" high-speed movement where one didn't exist before.

Wasn't it actually I-91 north to Route 2 east? And the current connection via Route 15 also existed, but it was a toll bridge.

Yes, true. But a lot of people, rather than continue onto 18, will go up Peasley Canyon and enter onto 5 from 320th. My family, for example, will take Peasley Canyon, which is very annoying to me (I go a few additional hundred feet and enter onto 18).

The I-95/Milford Parkway interchange is incomplete. There are no connections to the southbound Milford Parkway from north and south I-95. Also, northbound Milford Parkway has no connections to I-95. In a way, the connections are not needed heading southbound since the parkway ends at US 1 about 1/2 mile down.

[roadman65]

Exit 52 in Wayne, NJ along I-80 is notable for not having access to NJ 23 in both directions.  EB the interchange just serves parallel route US 46 as westbound I-80 is a complete interchange with NJ 23 for the sole purpose of serving NJ 23.

Plus all the Exit 52 on ramps are from NJ 23 as well. Even WB US 46 to do the opposite of going WB to WB, you have to exit onto NJ 23 NB to accomplish this.  Only SB NJ 23 is missing movement to WB I-80, but has directional signs now directing motorists to u turn south of US 46 back to NB NJ 23 to enter WB I-80 from the other side.

With the Willowbrook Mall being just south of I-80 on NJ 23, you figure it would have been addressed and taken care of years ago as one of those two missing ramps would be serving that particular shopping mall.  It is not even that hard to construct those two missing ramps (3 if you count SB NJ 23 to WB I-80) or even tie in a direct ramp from I-80 EB to the US 46 trumpet interchange leading into the mall which is directly south of I-80 just west of the NJ Transit overpass and just east of the Passaic River.  Having this would directly serve the mall and access to NJ 23 could be via another ramp to US 46 EB making that a par clo intersection.

I-35E at SH 121 in Lewisville, Texas. Two movements were left off when the interchange was constructed mid-2000's; but they will be added as part of the current project.

Movements that can be made via frontage roads directly at the interchange don't really count. Better one in the Metroplex would be southbound US 287 to northbound I-35W north of Fort Worth. 3 of the 4 movements exist, but that one requires using the turnaround at the next exit. Also the south SH 121/I-820 merge/split is missing both north-to-south movements.

Which can be made via frontage roads... (and a bit of SH 10 for I-820 north to SH 121 south)

And if frontage roads don't count, I-40 east to I-27 south.
