However, with the split Interstates (I-35W/I-35E in both TX and MN & I-69E/I-69C/I-69W in TX) & US Highways (and a few state highways), the letters are part of the route number. So, they wouldn't have any effect on the "role" part for relations. When given routing info, they'd act just like their non-lettered siblings. "Turn left onto Northbound I-35E on-ramp" or something similar. Also, I don't know why some people put the letter as a "modifier" in some of the relations[1]. Maybe we could also remove that line (since the ref line has the proper number still) when we convert everything to the cardinal directions. -James [1] - http://www.openstreetmap.org/browse/relation/416519 > Date: Wed, 27 Nov 2013 22:22:47 -0500 > From: saiarcot...@gmail.com > To: talk-us@openstreetmap.org > Subject: Re: [Talk-us] [josm-dev] Relation editor support for north/south and > east/west similar to forward/backward > > The same applies for I-35 in the DFW area; I-35E runs through Dallas > while I-35W runs through Fort Worth. > > Saikrishna Arcot > > On Wed 27 Nov 2013 03:56:51 PM EST, Richard Welty wrote: > > On 11/27/13 2:46 PM, John F.
