Routes that's basically a long ramp

[geek11111]

Like I-189.
Do you think it's good for a ramp to be numbered?

[Max Rockatansky]

CA 259 is an example of this.  Sometimes it gets reassurance shields where at other times it is signed as TO CA 210 or TO I-215.

Since it has its own interchange to Highland Ave, they'd have to consider the north part of it as a ramp to CA-210 and the south part as a ramp to I-215, and put signs on the bridge over Highland Ave saying you're now on CA-210 or I-215.

Here's one in California:

At least they have the decency to sign it as a freeway entrance ramp to I-80 and not a distinct route.

The I-564 Intermodal Connector in Norfolk connects I-564 and the Port of Virginia, plus a connection to Hampton Blvd and Gate 6 of Norfolk Naval Base.

It's an approximately 2 mile freeway connector built a few years back that is unnumbered and quite literally is just a long ramp.

One could argue that I-238 is functionally the ramp from I-880 to I-580...

[Amaury]

I don't know if this counts, but on Interstate 82 westbound, where it terminates at this exit–I don't know why it's just Exit instead of Exit 1, but that's for another discussion–just after the Exit sign, reassurance shields say the roadway is Interstate 90 westbound.

I-175 and I-375 St. Petersburg FL

What I don't get is why the on-ramps for I-82 cross each other. That's a whole extra bridge for nuthin'.

Until a recent extension, AZ 24 in Mesa was effectively a glorified on/off ramp for Ellsworth Rd. on the Loop 202.

244 did get its number (never signed in the field) as part of a larger project to provide a bypass for US 50 traffic getting from the Rancho Cordova/Folsom area west towards Natomas and towards I-80 heading to SF, of which the ramp to Auburn Boulevard is the only part ever built (as part of the then-I-880 project in the 1970s).

Other routes that basically fit this:

Since I-238 was mentioned, I-380 in the Bay Area also fits this to a degree - but was planned to be a longer route heading west to Pacifica, of which the carriageway and bridges at 380/280 are the only remaining evidence of this.

Route 262 almost fits this, but then has multiple intersections between the end of the freeway segment off I-880, and the portion heading to I-680.

Route 242 (former Route 24) in Concord

Route 77 in Oakland though maybe less so since the free-flowing ramps with I-880 have been gone for over 20 years, replaced with a diamond.

When completed, the post-1990s Route 11 will essentially just be a brief connection from Route 125/Route 905 to a new border crossing.

Arguably the west Route 90 between I-405 and Route 1 (Marina Freeway)

Route 217 between US 101 and Goleta

I-381 VA
I-395 MD
FL-451
FL-453
The current state of AL-108

None of them harm anyone by being signed.

It's also weird in that the advance signage has the only BGS I can recall seeing with the phrasing "EITHER LANE."

Butte, MT's I-115. Better yet, it's entirely concurrent with BL I-15/90.

[jp the roadgeek]

CT 11: From CT 2 to CT 82
CT 20 Bradley Connector: I-91 to the airport
CT 40: I-91 to CT 10
RI 4: From I-95 to US 1
RI 99: From RI 146 to RI
RI 403: From RI 4 to Quonset State Airport
And of course: I-587 in NY: Thruway to Kingston

[sprjus4]

Wade Ave in Raleigh, NC connects I-40 to the west with I-440 to the east.

[dgolub]

I-695 in the Bronx certainly seems like it would qualify.  While it's cool for roadgeeks, it probably creates more confusion than it alleviates for the general public.

[ilpt4u]

One could argue I-190 IL is a long ramp for ORD Airport and its various terminals and parking facilities

[hotdogPi]

We've had this thread before, and in that thread, I mentioned IN 641. Is it still the case?

[Quillz]

CA-217 is just a glorified off-ramp to access UC Santa Barbara.

[Life in Paradise]

IN 641 is now 5 miles long between I-70 and US 41.  There are two exits between the two endpoints.

[dlsterner]

The I-895 Spur routes in Baltimore are essentially glorified ramps between I-895 and (either I-97 or MD 2)

Although northbound on I-97, the "second chance" ramp to I-695 west (to allow access to the MD 648 interchange) is relatively recent and might legitimize things somewhat.
