I'm kind of fuzzy on the rules but I think 3-digit interstates that start with even numbers are loops right? So maybe this Houston to Austin road could be I-110 or something like that.

Its honestly crazy to me there's no interstate between Houston and Austin... both 71 and 290 are a royal PITA sometimes.

Correct, the Austin-Houston Interstate could be 110, 310, 510, 710, or 910.

The longest 3 digit Interstate that I know of is I-390 in New York State, it goes from Gates, NY (Rochester suburb) all the way down to Corning, NY in the southern tier.

Interstate 505 in California I think is the next longest, the bypass of Sacramento

So many useless interstate proposals in this thread. With few exceptions, we don’t need MORE interstates, we need BETTER interstates.

This is particularly true in the space between cities in the eastern half of the country. The interstate system was designed with well over 100 million fewer residents in the US. Almost all interstates should be 3 lanes each side minimum. I can’t count the number of times slow drivers in the left lane and truckers “passing” other truckers have caused slow traffic and dangerous conditions. Traffic jams should not occur in rural areas simply from heavy traffic, yet I experience it all the time. I-85 between Atlanta and Charlotte is one of many examples.

In large metro areas, there should be separated lanes for through traffic with minimal exits. If I’m traveling on 95 through DC, for example, there should be lanes that let me drive from the south side of DC to the north side of Baltimore with opportunities to enter or exit only near a few major interstate interchanges. I know some cities, including DC, have various express toll and HOV lanes, but those seem to be used more for locals and not those traveling through a metro area.

These would obviously be expensive, but I think they are far better investments than building random freeways from Amarillo to Nebraska or Houston to Indy.

Pennsylvania has two long three digit Interstates. Interstate 376 from Interstate 80 to the Pittsburgh area and Interstate 476 from Scranton to Philly. The latter breaks a numbering rule (three digit Interstates that start with an even number are supposed to be interstates that loop around metropolitan areas) and should be renumbered "Interstate 776" as a tribute to the year 1776.

now 295 also bucks that trend in three states PA, NJ, and DE


I like the 776 idea though 476 should really be odd numbered as it runs N/S




295 should be come 276 as a PA turnpike extension on the old 95 from Bucks county to Belmar NJ and is really now E/W

I-605 in California does the same thing, goes straight north to south from Duarte to Seal Beach, but starts with an even number

Interstate 270 in Maryland is also spur route despite it starting with an even number.

Technically, the 605 Freeway was designed to be a bypass of Downtown Los Angeles to the east, while the 210 serves that purpose to the North and the 405 bypasses it to the west. It's just that the area grew exponentially between the time the freeway was planned and when it was actually built. The odd-numbered 3DI's like the 110 and the 710 directly connect Downtown LA to the Port of Los Angeles-Long Beach, so they serve as spurs as 3DI's that start with odd-numbers are supposed to.

Actually, I always thought the rule for even 3-digit interstates was a loop like you mentioned and also when the 3-digit interstate connects two different 2-digit interstates (or the same 2-digit interstate, making it a bypass).

So with I-476 connecting I-81 in Clarks Summit, PA to I-95 in Chester, PA (it also connects to I-76 in West Conshohocken, PA), it is in fact is the proper numbering rule?

I never knew that one.
