IL: US-24 Not concurrent with I-474 in Peoria IL
« on: April 21, 2018, 12:43:01 pm »
I noticed that US24 uses the I-474 bridge over the Illinois River south of Peoria and I've traveled I-474 but it is not showing up as traveled on US24

IL: IL-29 not connected to US24 and I-74

IL29 is not showing as concurrent with I-74 over the Illinois River in Peoria and is also not concurrent with US24 from I-74 to West Camp St in Peoria.  The first image is my travel on IL29.  The second is all of my traveled routes in that area.

That is because:
-US 24 and I-474 at exit 6 differ by the last three decimal places in the latitude
-I-74 and IL 29 use one data point for exit 95A while US 24, US 150, and IL 116 use a slightly different one
-I-74 and IL 29 have different data points for exit 93. (One is closer to Adams Street while the other splits the difference between Adams and Jefferson.)

Naturally, I have no clue why those are, but I will make the necessary fixes.

(I merged the topics because "Peoria area concurrency issues" go together.)
