Well, I was just testing MapQuest and it thinks that I-74's split there from I-77 is the main highway (somewhat).<BR>
<A href="http://open.mapquest.com/?le=t&hk=7-OEgrKIB6&vs">http://open.mapquest.com/?le=t&hk=7-OEgrKIB6&vs</A>=<BR>
It says "<SPAN class=nav-cmd><SPAN class=type>Stay</SPAN> <SPAN class=relative-dir>STRAIGHT</SPAN> to go onto <SPAN class=street-name><SPAN class=regular><SPAN class=first>I-74 E</SPAN></SPAN></SPAN>." The problem is it's a "Left" exit.</SPAN><BR>
<SPAN class=nav-cmd>The line should say something like: "Take Left Exit #101 to continue on I-74 East towards Mt Airy/Winston-Salem." This is what Google says on their map: "<SPAN id=dirsegtext_0_2 class=dirsegtext>Slight left at <B>I-74 E</B> (signs for <B>Mt Airy/<WBR>Winston - Salem</B>)". Heck, I've been fighting with Google trying to get them to mention the Exit number for that step as well, but haven't had much luck.</SPAN></SPAN><BR>
<SPAN class=nav-cmd></SPAN><SPAN class=nav-cmd>This is what we need to work with MapQuest to fix. Maybe a special "exit_left=yes" or "left_exit=yes" tag?</SPAN><BR> <BR>

<BLOCKQUOTE class=cite>You know guys, we should also figure out right here and now how to deal with "left" exits at Interstate splits where both ways are "motorways".
