Illinois: 1 or 110?

Chicago–Kansas City Expressway gives 328 miles for IL 110 (sourced to the Goog), while Illinois Route 1 says 325.59 miles (I get 324 on the Goog). It looks like IL 110 barely beats out IL 1, but it'd be nice to have a non-Goog figure. --NE2 00:54, 29 January 2015 (UTC)[reply]

I will start mileposting IL 1 from the GIS data I have, but it may take a few days. –Fredddie ™ 03:02, 29 January 2015 (UTC)[reply]

Ugh, all the mileposts go from north to south and reset at the county lines. –Fredddie ™ 03:25, 29 January 2015 (UTC)[reply]

OK, I get 322.48, but that's not counting a one-way section in Paris. That bumps it to 324.41 miles. –Fredddie ™ 06:03, 29 January 2015 (UTC)[reply]

Indiana: 67 or 37?

I wonder... Whenever I-69 is completed, will SR 37 be signed with I-69 for 100+ miles from Bloomington to Fishers? -User:EBGamingWiki; 12:04, 19 May 2016 (EDT)

Rhode Island: 114 or 138?

RI 114 is 45.7 miles long, but RI 138 is 48.3 miles long. Why is RI 114 listed as the longest state route in Rhode Island if RI 138 is 2.6 miles longer?

New Jersey: 47 or 444?

New Jersey Route 47 is only the longest signed state highway. If you count unsigned highways, New Jersey Route 444 is longer. Should this be changed? --2600:1700:D500:C6D0:6D55:3665:95A7:8ED (talk) 03:15, 22 November 2021 (UTC)[reply]

Isn't this already addressed by footnote d, which mentions that Route 444 is unsigned. Imzadi 1979 → 17:24, 23 November 2021 (UTC)[reply]

Welp I guess I'm unobservant. :P --2600:1700:D500:C6D0:998E:9D3F:8F47:E03C (talk) 02:20, 24 November 2021 (UTC)[reply]

South Dakota: 34 is longest

The article lists SD 20 as longest but lists a different mileage than the page for South Dakota Highway 20. When referencing the State Highway Logs produced by the SD DOT, SD 20 is approximately 385 miles in length. South Dakota Highway 34 is approximately 419 miles in length 216.81.94.73 (talk) 18:22, 25 July 2023 (UTC)[reply]
