Interstates that terminate in largest cities of a specific state at each end

[roadman65]

I-90 the country's longest interstate, happens to terminate in Seattle, the largest city in Washington, and then at its other end in Boston, the largest city of Massachusetts.

I do not think that there are any others out there as I-10 comes close, but not close enough as its western end is just outside LA's city limits in Santa Monica.

We have many that transit the states largest cities, but do we have any that do what I-90 does?

[hotdogPi]

I-94, although the west end (Billings, MT) is not nearly as large.

Assuming 3DIs don't count: I-H1, I-H2, I-H3.

To help others get serious answers:

I-22 works if you count the west end as Memphis.

If I-49 is chosen as the route number when the US 90 corridor is completed as an interstate it could work. New Orleans in Louisiana and Kansas City in Missouri.

Western I-84 from Salt Lake City to Portland, if you count Echo as close enough to SLC.

I-55 with New Orleans and Chicago

I-55 with New Orleans and Chicago

Not quite as I-55 does not enter New Orleans.  You need to head east on I-10 to reach it.

New Orleans Metro

Far enough from New Orleans to where I wouldn't count it either.  Furthermore, the OP cited that I-10 does not count, even though Santa Monica is right next door to LA.

I-H1/2/3 technically counts, but technically doesn't either.  Honolulu is a consolidated city-county, but what the Census designates as Honolulu stops short of reaching I-H3.  I know from personal experience that there are administrative districts on Oahu and Honolulu is but one of them.

"one" mentioned I-94, but that ends in Port Huron, not Detroit.

Once Interstate 11 is built, it will count (Phoenix, Arizona and Las Vegas, Nevada), that is unless it's extended to Reno, but that is very unlikely.

I-10, LA to Jacksonville.

I-10, LA to Jacksonville.

I think I-10 should count. Santa Monica is a suburb of LA. I-55 is close enough to count also. It ends only 10 miles outside of New Orleans.

I agree, there are few interstates (at least in the eastern half of the country) that terminate IN major cities. Most of them tend to terminate in suburbia.

I-76
West End: Denver
East End: Philadelphia

Nice try.  Ends in NJ.  Not even the same state

I-11 won't end within Phoenix city limits. Wickenburg or Buckeye, most likely. Maybe Casa Grande if it ever gets built that far.

The debate seems to be whether "metro area" counts.  OP made it pretty clear that it doesn't (unless he plans on loosening/changing it). So far, I-90 seems to be the only example.

Once upon a time, I-71 ended in the largest cities of their respective states (Louisville and Cleveland), but they've since been overtaken by Lexington and Columbus, IIRC.

[WashuOtaku]

I-22 works if you count the west end as Memphis.

I wouldn't accept I-22 for two reasons.

• Only exists in Alabama at this time.
• Does not end in Memphis even in current propose routing, Mississippi plans it to end at I-269.

Lexington has not been the largest city in Kentucky since January 1, 2003.  Louisville is now over 550,000.  If you disqualify consolidated city-county governments, the largest city in Kentucky would be Bowling Green.

If that's the case, then we ought to count MSA rather than municipality. Jacksonville is far from the largest MSA in Florida (Miami-Ft. Lauderdale, Tampa Bay Area and Orlando coming before).

If you are counting metro areas, south Florida is the largest metro.

If again on Metro, easy answer would be I-45. DFW to Hou.

They're in the same state, therefore they cannot both be the largest.
