Giving roads an I-70 in MD style starting mileage sign

I-15
SB--Salt Lake City, Las Vegas, Barstow, San Diego

I'd pick any of Great Falls, Butte, Idaho Falls, or Pocatello over Barstow if we're talking about southbound.

Agreed. I'd also pick Riverside over Barstow for NB. Riverside, Las Vegas, SLC, Sweet Grass

For I-81:

Northbound (mileage from I-40): Roanoke 225, Harrisburg 507, Syracuse 755, Thousand Islands 853

Southbound (Mileage from the Canadian border): Binghamton 172, Harrisburg 351, Roanoke 641, Dandridge TN 853 (Or, could use Knoxville 888)


Another idea in addition to the spirit of this thread, as I-81 is used as an I-95 bypass, one could list cities via other interstates at certain points along the route.

A sign on northbound I-81 just north of I-77 south could read Washington DC via I-66 295, Philadelphia via I-76 453, New York City via I-78 515, Boston via I-84 and I-90 756.

Southbound signage might be a bit more complicated, depending on the cities chosen. From a point just south of I-66, Charleston WV via I-64 290, Charlotte via I-77 347, Knoxville via I-40 409, Nashville via I-40 588 would be easy.

But, many travelers on I-81 are heading to further destinations. So how complicated do you get? Atlanta via I-77 & I-85 583? Jacksonville via I-77 & I-26 & I-95 729? Miami via I-77 & I-26 & I-95 1080? Would that be helpful, confusing, or not a concern at all?

81 is a weird one for sure. Hugely important corridor but no major cities on the actual route, which I suppose is the point. I do kinda like the DC Philly NYC thing on NB but you're right, SB things get confusing

And 70 W Denver, Kansas City (should replace St Louis in the real sign imo), Indianapolis, Baltimore

Just out of idle curiosity, why do you think Kansas City should replace Saint Louis? Its MSA has a 27% bigger population than Kansas City's.

Personal bias more than anything lol. I'm from just outside KC. I could argue that it comes down to KC city proper being well bigger than StL, but it probably has more to do with wanting the Royals to beat the Cardinals.

I-64 WB: Richmond, Charleston, Louisville, St. Louis.
I-64 EB: Louisville, Charleston, Richmond, Norfolk/VB/Chesapeake (all three debatable)
