Exit number ranges for metropolitan areas

[jaehak]

CSAs/MSAs be damned, I'm way more in favor of mapman1071's definition of this exercise than, say, Henry's. CSA/MSA are TV market measures, but I don't think they really apply to roads. Bellingham is in the Seattle TV market and likely cheers for the Mariners, but it's 100 miles from Seattle. Nobody is commuting into Seattle for work every day from Bellingham. The parameters set by mapman1071 do a better job of defining urban/suburban metro PHX than a lot of these CSA/MSA posts IMHO. The only reason parts of WV and PA are considered DC metro is because of commuter trains, it has nothing to do with I-81.

Metro Detroit

I-75: Exits 26-93
I-94: Exits 187-248
I-96: Exits 153-192

I-96 ends in Detroit while the other two go through Detroit and I'm not sure what the extreme limits of the Metro area are.

Charleston, SC

I-26: Exits 187-221
I-526: The whole thing

Columbia

I-20: Exits 39-98 (real influence goes from 51-87)
I-26: Exits 91-129
I-77: End to Exit 32
I-126: The entire road

No MARC commuter trains go to Franklin or Fulton County, PA.  Yet, oddly, they are part of the DC television market.  I-81 does pass through the latter, though.

I know Portland's been done, but I think it would be fairer to use the Urban Growth Boundary to determine the metro area. This technically means no Washington State, sooooo...

I-5: 283-308
I-84: 1 to 17
I-205: 6 to 24B
I-405: 1A to 3
US-26: 61(A) to 74
OR-217: 1 to 7

San Francisco Bay Area

US 101 from south edge of Santa Clara County to north edge of Marin County - Exit 355 (Monterey Road/former US 101 in Gilroy) to Exit 467 (San Antonio Road, just north of Novato)
I-80 from western terminus at US 101 in San Francisco to the edge of Dixon (last city going northeast in Solano County) - Exit 1A/1B (US 101) to Exit 67 (Pedrick Road)
I-580 from western terminus at US 101 in San Rafael to the I-205 split near Altamont (in Alameda County) - Exit 1 to Exit 65

---

Metro Sacramento

I-5: Exit 498 (Twin Cities Road) to Exit 541 (Route 16/former US 99W in Woodland)
I-80: Exit 70 (Route 113 near Davis) to Exit 123 (Bell Road near Auburn)
Route 99: Exit 274A in Galt to Exit 311 (Riego Road) near Pleasant Grove
US 50: Exit 1 (I-80 in West Sacramento) to Exit 49 in Placerville

---

San Diego

I-5: Exit 1A in San Ysidro to Exit 54C at Camp Pendleton
I-8: Exit 1 (Mission Bay) to Exit 33 in Alpine
Route 15/I-15: Exit 1A (I-5 in Barrio Logan) to Exit 54 in Rainbow

For Kansas City, I'm going to go with my opinion since the MSA & CSA are both too extensive.

I-29: Exit 1A (I-35) to Exit 20 (MO 92/Platte City)

I-35: Exit 214 (Lone Elm Rd./159th St. in Olathe, KS) to Exit 20 (US 69 & MO 33 in Liberty, MO)

I-49: Exit 172 (N Cass Pkwy in Raymore) to Exit 187 (I-435/I-470)

I-70: Exit 224 (US 24/40/73 & K-7 in Bonner Springs, KS) to Exit 24 (US 40 in Grain Valley, MO)

Boston/Providence
I-95: (RI) Exits 1-30 (MA) 1-60 (NH) 1-7

Such looks more like statewide listings than regional/metropolitan.  For the Greater Boston area; Exits 11-50 (MA) would be more appropriate.

I-90: Exits 26-9

More like Exits 12-26 for the Greater Boston area.

I-84: (MA) Exits 1-3B

I would not include at all; I-84's too far from the Greater Boston area.

I-93: (MA) Exits 1-48

For the greater Boston area; Exits 1-37C would be more accurate.

I find Columbus, Ohio, to be very interesting in relation to this, because both I-70 and I-71 have exits right around 100 within the city.

[PHLBOS]

Philadelphia metropolitan area:

PA:
I-95 (entire length)
I-76 (Exits 326-351)
I-276 (entire length)
I-476 (Exits 1-31)
I-676 (entire length)

NJ:
I-76 (entire length)
I-295 (Exits 11-47)
I-676 (entire length)
NJTP (Exits 2-5)
NJ 42 (Exits 7-14)
NJ 55 (Exits 56-58)

This is a very interesting concept!


While it's not exactly a very large city and metro area (compared to places like Boston, Seattle, Atlanta, etc.), I'll do Chattanooga, Tennessee:

Interstate 75 => Exit 348 (GA) to Exit 11 (TN) => total length in miles: 18 miles

Interstate 24 => Exit 174 all the way to the eastern terminus (end) at Exit 185 => total length in miles: 11 miles

Interstate 59 => Its northern terminus barely misses the edge of the Chattanooga Metro Area, so no exits on it are included (the reason it's mentioned at all is due to its proximity to Chattanooga).


Now for something bigger, here's Nashville, Tennessee:

Interstate 65 => Exit 46 (here at the US 412 interchange may be at slight stretch, but at the very least it begins at Exit 53, which is at limited-access TN 396) to Exit 98 => using Exit 46 as the starting point, the total length in miles is: 52 miles

Interstate 40 => Exit 192 to Exit 239 => total length in miles: 47 miles

Interstate 24 => Exit 35 to Exit 84 => total length in miles: 49 miles

Interstate 440 => all exits

Interstate 840 => I apologize for my incompetence, but due to I-840 being a partial beltway, it is practically impossible for me personally to calculate the metropolitan exits of this interstate, so unless someone else has the competence to do this one, I'll leave it as: N/A

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

I-985: 1 to 8 (north of that is probably linked more to Gainesville than Atlanta)

Despite Gainesville's modest size, I'd say that it is more or less becoming a suburb of the Greater Atlanta Metro Area, if not already, and the sprawl is only increasing and filling in even more as time goes on. As crazy as this may sound, Athens is seemingly headed in the same direction. It is only a matter of time before Atlanta's and Athens' sprawl are completely inevitably linked.

CSA/MSA are TV market measures

??? CSA/MSAs are determined by commuting patterns and have nothing to do with television markets. For example San Diego is the only MSA/TV market in California that lines up; none of the other 25 MSAs or 7 CSAs line up with a TV market (and most are off by a significant amount).

I-4 for Orlando is 55 to 103 as the Orlando area does start at US 27 west of Disney.  The St. Johns River is the east end though one could argue that Deltona, Orange City, and DeLand are part of Orlando's metro area which would lengthen the range even more as the last DeLand exit is 118 at SR 44.

I've always thought of the Orlando Metro Area as extending out all the way to DeLand, even though the St. Johns River is a big geographical barrier (particularly because of Lake Monroe).

Milwaukee
I-41 Exits 38-76
