Title: IN: I-90 at US 41 (Exit 5)
Post by: Markkos1992 on March 23, 2019, 07:41:52 pm
I think that the I-90(5) point on US 41 (https://www.google.com/maps/@41.6457563,-87.5087435,3a,75y,199.24h,98.83t/data=!3m6!1e1!3m4!1sQclaqZFtxWDC2o5e4RtGoQ!2e0!7i16384!8i8192) should be added to I-90 for the purposes of a graph connection since US 41 directly connects to I-90 EB here..

mapcat, you may have been planning on doing this later in the year.

This is on my list of things to investigate this summer.

This is pretty near where I live.  I-90 Exit 5 is a little strange.  The Eastbound exit ramp puts you out right at Calumet and 142nd (not currently a waypoint).  The Westbound exit/entrance ramps are from 141st street a bit east of Calumet (with a waypoint at Calumet labeled 141stSt), and the Eastbound entrance ramp is on Calumet a bit north of 141st street (labeled I-90(5)).  If, in your travels, you only use the Eastbound exit at this interchange and then travel south on Calumet, you never pass through the two existing waypoints.  I guess the most accurate way to fix this would be to add a waypoint called 142ndSt, since I-90(5) is already used. 

Side note: For I-90, the Exit 5 waypoint is directly on the Westbound exit ramp and perhaps for best accuracy should be moved halfway between the Eastbound and Westbound ramps.
