Two control cities signed on the same BGS for the same road but neither on route

[ilpt4u]

I think some of y'all are missing a key part of what the OP was looking for. It's easy to find signs with 2 control cities where 1 control city is for one direction and 1 control city is for the opposite direction.

OP's example was of, i.e. a pull-through sign with 2 control cities in the same direction.

I-255 South/US 50 West in Illinois at I-64 with Controls of Memphis and Tulsa

I posted an example with SB I-270 using Tulsa and Memphis upthread; didn't know I-255 did the same. That's new to me.

This BGS panel was replaced when IDOT D8 reconstructed I-255 between IL 15 and I-64 last year, but the new panel (which I drove by today and still didn't grab a pic...one of these days...) still lists the Memphis and Tulsa controls

There is even a Distance sign for both Memphis and Tulsa on I-255 in the Metro East:

The pullthrough sign in the first image isn't displayed in the best way imo. Without context, I would've thought that I-255 and US 50 would split soon, and the left 2 lanes are for I-255 south to Memphis, right 2 lanes for US 50 west to Tulsa, with both options sharing the middle lane.

The new pullthru is much better - it does not have that vertical line between the 2 shields, and the Controls are vertically stacked, pretty sure - aka a much more standard IDOT Pullthru

Of course, neither I-255 nor US 50 go to either Memphis or Tulsa, but that is of minor concern

I-295 North at the Del Mem Bridge:  https://goo.gl/maps/4h9AV7LXKMie96UR6 .  295 remains about 2 miles outside both Camden & Trenton: 

I-495 North, south of Wilmington.  https://goo.gl/maps/EofXERjVEWYJrM228 .  Philly is about 12 miles north of 495's terminus, and Port of Wilmington isn't even a city, but rather a location east of 495.

I-495 serves neither Philadelphia nor Baltimore

Nor the Delaware Memorial Bridge!

How many examples are on 2dis? Seems like a lot of them are on 3dis.

One of the original purposes of the interstate system was to connect cities.  So by default, the interstate should be serving their signed control cities.

HighwayStar, is that you?

I-97 South uses "Annapolis" & "Bay Bridge" - its southern terminus is in Parole (Annapolis suburb) and one must use US 50 East to reach both destinations.

US-101 Redwood Highway in San Rafael/Novato area has a BGS sign for CA-37 indicating Sonoma and Sacramento as the control cities. However to reach Sacramento from Marin County one has to clinch CA-37 to Vallejo and head east on I-80.

For Sonoma it is through CA-121.

I-97 South uses "Annapolis" & "Bay Bridge" - its southern terminus is in Parole (Annapolis suburb) and one must use US 50 East to reach both destinations.

I find it interesting that you can eventually get to the other (and more well known) bay bridge by driving on US 50 (including the decommissioned part west of its current western terminus) in the opposite direction of the above sign.

Plenty of 3dis alone fall into this category.  In Michigan, I-696's control cities are Lansing and Port Huron, and the route doesn't go near either of them.  I-275's control cities are Flint and Toledo, and the route doesn't go near either of them.  Within Flint, I-475's control cities are Saginaw and Detroit, and the route doesn't go near either of them.

This isn't any big deal to me.  Control cities should give reassurance that one is heading in the correct direction, that's all.  Whether the route enters that city is irrelevant.

In all cases the highways parent route connects to those cities except for Port Huron but I-696 ends at I-94, personally I think Roseville should be the control city on EB I-696. You could say the same thing about I-496 having Detroit as a control city. But I think the idea here is that those highways are connecting back to their parent route and their parent route will take you there, except for I-275 with Flint but we all know that was supposed to end in Davisburg.

I-80 at Toledo has control cities Chicago (West) and Cleveland (East); I-80 does not enter either city.

The I-275 extension was cancelled more than 40 years ago; there have been numerous sign replacements since then and Flint has remained the control.  And most motorists don't think about and couldn't care less about any correlation between "parent" and "child" routes.

[Roadgeekteen]

Flint should not be signed on I-275 unless the road is completed, it's quite indirect from I-275. It should be signed for Novi.

[Flint1979]

The control city should be Livonia and I-275 should end at the M-14/I-96 interchange.

[Flint1979]

If everything went as planned I-96 was suppose to follow what is the M-5 freeway and then parallel with Grand River Avenue but thankfully that was revolted as well. I'm happy that most of Detroit's freeways were revolted the city is already carved up enough from freeways.

I-275 would have had to cut around numerous lakes for one thing that would have been fun.

The I-275 extension was cancelled more than 40 years ago; there have been numerous sign replacements since then and Flint has remained the control.

Through the last 50-60 years, the Long Beach Freeway northbound control after the number originally changed from 15 to 7 (and then from 7 to 710) has been "Pasadena", even after that extension got iced a year or two ago and the road at no point has ever reached Pasadena!

[Occidental Tourist]

I don't believe there are any BGS's posted, but there are plenty of other signs listing Phoenix and Tucson as the control cities for e/b I-8 between Yuma and Gila Bend.
