Highway-advance signs with no control cities

[golden eagle]

On I-220 in Jackson, there is no control city for US 80. There are also no control cities for I-220 at US 49 on the north side of town.

[hobsini2]

I-494 and 694 in Minneapolis very rarely use a control city at all.

[pianocello]

Exit 9 on I-80 in IL for US-6 has no control city (the signs on the ramp give directions for Moline and Geneseo; I think Coal Valley and/or Colona would make good control cities.)

[huskeroadgeek]

I-235, I-435 and I-635 in Kansas don't use control cities. Interestingly, I-435 in Missouri uses two cities in Kansas as control cities(Topeka for I-435 SB S. of I-29, and Wichita for I-435 SB(and WB) S. of I-35, but those cities never appear on signs as control cities on I-435 in Kansas.

Also, alot of the exits on the Illinois tollways do not use control cities at all at some exits but will post a sign for "___ Next Exit".
I-88: IL 47, IL 31-56 East, IL 59, IL 53, IL 83
I-90: IL 31, IL 25, IL 59

I-4 at Exit 38 for FL 33 near Lakeland, FL.
I-95 at two places for US 301 near Emporia, VA at both Exits 12 and 17.
I-29 and I-90 at Sioux Falls, SD for I-229.  It used to have none at any of its interstates crossings except for I-90 & I-190.
I-4 entrance ramps from FL 435 SB near Universal Studios in Orlando, FL have large overheads missing control points.
FL 408 used to not have control cities for I-4 in Orlando at Exit 10A except on the ramps before OOCEA installed the present signing.

Then there's I-355 from I-55 which has no control cities on the the advance signage, but uses them on the exit signage.

Another I-95/US 301 exit in Virginia is exit 45. Some of the secondary routes in this area alao don't have control cities, such as exit 33 (SR 602). Also, I-85 at exit 63 in Virginia has no control cities for US 1.

[Brian556]

In Denton, Texas, The BGS's for I-35 on Loop 288 don't have any control cities.

[Stratuscaster]

Then there's I-355 from I-55 which has no control cities on the the advance signage, but uses them on the exit signage.

I thought I had read that something similar was the "proper" (or at least an accepted) signing method - Ohio Turnpike uses it such a method. Advance signs are shields only, control cities appear at the signs right before and at the exit.

Then again, are "Northwest Suburbs" and "Southwest Suburbs" really control "cities"?

[national highway 1]

The most famous example: I-605 CA, and also judging from the signs for CA 91 and I-105...

[The High Plains Traveler]

I-494 and 694 in Minneapolis very rarely use a control city at all.

Almost none of the interchanges within the 494-694 loop use control cities, except for Minneapolis and St. Paul. As an example, northbound on I-35W at the interchange with 94, the only control city is St. Paul along I-94 east. Nothing for 35W north or 94 west.

[txstateends]

In Dallas, I-30 BGSs on I-45 NB and US 75 (hidden I-345) SB have no control cities for the east (should say Texarkana) or west (should say Fort Worth) advance or exit signage.  Even dating back to when the BGSs had I-30 (and before, when it was originally I-20), US 67, and US 80 shields there were no control cities on those, either direction.

Is the question about "control cities" or just destinations?  Control Cities are major traffic-generating cities along a route.  The OP cites I-220 in Jackson, MS, which is a connecting route from I-20 to I-55 serving only the Jackson metropolitan area, thus the major traffic-generating city on that route is Jackson, itself and probably wouldn't make sense to use as a "control city".

Some states though put control cities on such routes based on the routes they connect with. Since I-220 functions as a connection from I-55 north of Jackson to I-20 west of Jackson, you could use Grenada for I-220 North(which is the control city for I-55 North in Jackson) and Vicksburg for I-220 South(which is the control city for I-20 West in Jackson).

[PHLBOS]

In CT, one of the I-95/US 1 interchanges (I believe that it's either Exit 39A-B in the Milford area) lists no control cities/destinations on the exit signage for US 1.

Exit signage for NY 100 along I-287 Westbound (Exit 5) near Fairview lists no control cities/destinations as well.

[sp_redelectric]

The only example I'm aware of is SR 500 off of I-5.  But there isn't really a logical control city for SR 500 as it mostly serves as a commuter route from the northeastly suburbs of Vancouver to I-5 and Portland.  SR 500 officially ends in Camas, but it is more logically accessed via SR 14 from I-5.  And SR 500 becomes SR 503 in Hazel Dell which goes to Battle Ground, but it is also accessed via SR 502.

Is the question about "control cities" or just destinations?

As a more general question, is it possible to unambiguously determine control cities from signs?

I've always treated the two terms as synonymous, while fully aware that I'm probably incorrect in doing so.

Correct! It's simply signed as either US Route 1 NORTH and US Route 1 SOUTH. Basically the same for Exits 39A and 39B.

I-40 EB in New Mexico

How exit ahead signs with no routes nor 'control cities.'


I-40 EB in New Mexico

But unlike most unnamed exits I've seen, this has gas and food. For a long time, off I-25 there was otherwise unnamed Exit 191 just south of Denver, in a temporarily undeveloped but growing area between Denver's southern suburbs and Castle Rock . (For reference, CO-/E-470 is Exit 194). It finally was eliminated in favor of a new interchange with a real name. In Colorado, this type of exit often gets named for a long-gone hamlet, and in other states (e.g., Utah) they get a generic designation like "Ranch Road".

This is a common thing for most rural unnamed exits out west, because there is literally nothing else accessible from that exit.

All control cities are destinations, but not all destinations are control cities.

AASHTO maintains a list of Control Cities along each interstate highway.  These are selected by each state as major traffic generators for that route.  For example, in Iowa, I-80 includes Council Bluffs, Des Moines, Iowa City and Davenport as control cities.

I don't think it's the intent to differentiate the two for the general motorist.  Control cities are used to provide consistency and better directional reference to local and non-local travelers.

I've seen those along I-90 in South Dakota.  US 67/167 in North Little Rock used to have an "Exit 2"  before the most recent rebuild
