Exit number ranges for metropolitan areas

[JJBers]

I was looking a atlas yesterday, and I noticed that I-10 in LA area went upwards of 80 exits, so I deiced to make a list of a few metro areas, and the exit number ranges for their interstates. I'm only doing 2dis'.

NYC
I-78: Exits 7-58B...then 14-14B
I-87: Exits 1-17 and 2-14
I-84: (NY) Exits 1-21 (PA) 20-53
I-95: (NY) Exits 1-22 (NJ) 7-16W...then it picks up I-80's exit numbers, which leads it going from 69-74.
I-80: Exits 25-67
Boston/Providence
I-95: (RI) Exits 1-30 (MA) 1-60 (NH) 1-7
I-90: Exits 26-9
I-84: (MA) Exits 1-3B (CT) 72
I-93: (MA) Exits 1-48 (NH) 1-23
I-89: Exits 1-12
Hartford
I-91: Exits 20-49
I-84: Exits 28-71, 73-74
I'll expand this later on.

How are Tilton NH and New London NH in the Boston metro area? Kittery ME deserves to be counted much more than central NH (although I do think it is a bit too far).

I don't know...the CSA area showed those cities being part of it. Kittery's county wasn't included in that list.

I-87: Exits 2-17

I think it's interesting that exit 1 of I-87, despite being in NYC itself, is not in the NYC metro area.  I have learned a new thing about geography today!

Also worth noting that it's 2-14 and 1-17, because of the Thruway reset.

It is 100 miles from New London to Boston. New London is in pretty rural New Hampshire.

The way JJ is ranking these will not really work in the rest of the country, given that everybody outside NY and New England (excluding Maine) uses a milepost-based system.

Sure, one could still range the exit numbers, but those exit numbers have a totally different meaning outside the Northeast.

If we're talking entire metro areas and not just the city, I-95 in the Baltimore metro area is exits 35 to 89.

[ilpt4u]

Are NW IN and SE WI considered part of the Chicagoland metro area?

If no/just IL, then I-94 is IL Exit 74 to Exit 1, border to border, not counting I-80 exits 161 and 160, at the 80/94 duplex, approaching the IN border

If adding in NW IN, add in IN Exit 40 to Exit 1

If adding in extreme SE WI...I would probably consider Kenosha, WI "neutral" territory, and exclusive Milwaukee suburbs beginning around Racine (tho this is certainly up to debate/further discussion)...so WI Exit 347 to Exit 340

For NYC: I would narrow I-78 and I-80 to those exits inside I-287.  I-84 should just be the NY exits.  The skip in I-95 exits in NJ north of the Turnpike is actually based on mileage from West Trenton assuming the Somerset Freeway mileage, not I-80 mileage.  I would also extend I-95 to Exit 15 in CT.

Boston/Providence:  I would only include exits from RI Exit 8 northward on I-95.  I-84 and I-89 should be cut and I-93 should only extend to Exit 17 in NH.

Hartford: I-84 should be 27 (I-691) to 68 (UConn Exit) and I-91 Exits 21-49.

Chicagoland

I-90 Exits 42-107 (IL) and Exits 1-25 ish (IN)

I-94 Exits 1-74 (IL) and Exits 1-26 (IN) (I don't consider LaPorte County as part of Chicagoland)

I-88 Exits 109-138

I-55 Exits 236-293

I-80 Exits 126-161

I-57 Exits 327-357

[jaehak]

I'm with you on most of those. I'd put 57 at 140 and I've always considered the 80-55 interchange as the start of Chicagoland for both roads.

[TheHighwayMan3561]

Minneapolis/St. Paul:

I-94 Exits 207-258 (Rogers-Lakeland), and WI Exits 1-10 (Hudson-New Richmond)

I-35(E) Exits 84-132 (Lakeville-Forest Lake)

[tribar]

I'm with you on most of those. I'd put 57 at 140 and I've always considered the 80-55 interchange as the start of Chicagoland for both roads.

I contemplated doing that for 80/55 but I decided to include the rest of Will County for both. To me Chicagoland is Cook, DuPage, Lake (IL), Kane, McHenry, Kendall, Lake (IN) and Porter.

For Philly: Every interchange on I-95 in PA, DE and NJ (the original part around Trenton) is in the Philly Metro area, for a total of, I believe, 47 exits (and that doesn't include I-95's NJ Turnpike exits).

NYC
I-95: (NY) Exits 1-22 (NJ) 7-16W...then it picks up I-80's exit numbers, which leads it going from 69-74.

For NYC: I would narrow I-78 and I-80 to those exits inside I-287.  I-84 should just be the NY exits.  The skip in I-95 exits in NJ north of the Turnpike is actually based on mileage from West Trenton assuming the Somerset Freeway mileage, not I-80 mileage.  I would also extend I-95 to Exit 15 in CT.

I wouldn't include Exit 7 of the NJ Turnpike at all - you're at minimum 40 miles from any point in NYC (which would be Staten Island), yet only 20 miles from Philadelphia. 

Loosing speaking, anything south of Exit 9 on the NJ Turnpike is pretty far removed from the NYC area.  Understand that there are people that live in South Jersey and the Poconos that travel a few hours each day to get to work in the Big Apple, so the NYC metro area tends to be a bit overstated by some.

I suppose I need to do all 2DI's in the Baltimore area.

I-95: 35 to 89
I-70: 68 to 94
I-83: entire thing, 1 to 37
I-97: entire thing, 5 to 17

And can I do DC too?

I-66: pretty much the entire thing, 6 to 75
I-68: 72 to 82
I-70: 1 to 62
I-81: 300 to 323 in Virginia, entire 26 miles in West Virginia, entire 11 miles in Maryland, 1 to 24 in Pennsylvania
I-95: 118 to 177 in Virginia, 2 to 33 in Maryland

[Eth]

Without looking up any definitions or county lines and just going with my gut, Atlanta:

I-20: 24 to 93
I-75: 201 to 293
I-85: 41 to 129
I-285: all
I-675: all
I-575: 1 to 20
I-985: 1 to 8 (north of that is probably linked more to Gainesville than Atlanta)

[02 Park Ave]

I think that this information would be more useful if it was broken down by county rather than for an entire CSA.

[Jmiles32]

I'll do Richmond-Petersburg VA(basically wherever the tree medians end/begin except in the case of I-95 south)

I-64: 173 to 205
I-85: 61 to 69
I-95: 45 to 92

[cwf1701]

for Metro Detroit (Wayne Oakland and Macomb county):

I-94  Exit 190-248
I-96  Exit 155-192
I-75  Exit 27-98

[Alps]

I'll expand this later on.

You already did... far outside any reasonable range.

[Buffaboy]

Well for I-90 near Buffalo, there's a sign that says "Greater Niagara Region Exits 57-47," although if you measure from barrier to barrier it's really exits 55-50.

Or if you want to make a fictional "loop" using NY-179, US 20 and NY-78, that would be from Exits 56 to 49.

[Bickendan]

Portland: I-5 282A to 14
I-84 1 to 17
I-205 entire length (1 to 36)
US 26 53 to 74
WA 14 1 to 14
