When it comes to Interstates multiplexing, I think we should list first the one that the exit numbers are for on the highway. Some examples would be as follows:<BR> <BR>"ref=I 76;I 70" on the PA Turnpike since I-76 is the "main" route and all the exits along there use I-76's mileage.<BR>"ref=I 77;I 74" in NC since I-77's mileage is used for the mile markers.<BR>"ref=I 77;I 64" in WV since the entire WV Turnpike is I-77 (and all exits are in I-77 mileage) and I-64 is just "visiting".<BR> <BR>If both Interstates are going in the same direction and share the mileage since they both entered the state at the same time (I-20 and I-59 in AL), I-20 would go first there since it's the lower numbered route.<BR> <BR> <BR>James<br> <BR><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">Date: Fri, 27 Jul 2012 09:34:24 -0700<br>To: Alan_Mintz+OSM@Earthlink.Net; Talk-us@openstreetmap.org<br>From: techlady@techlady.com<br>Subject: Re: [Talk-us] Highway ref again.<br><br>

I think
you've identified another area where clarity is needed: What order should
be used when entering multiple refs. I tend to do it with interstates
first, then US routes, then state routes, within each group by number,
low to high. However, a definite rule would be helpful.<br><br>
