 would encourage everyone to check out the maps of NHS routes to see if 
they make sense for your state. [4] One comment I must make about this 
network is that it includes urban principal arterials as a part of this 
network. I would not make any of those be trunk, since that would mean 
that there would be way too many trunk roads in an urban area. 
Personally, I don't think roads that are part of the NHS should be 
tagged as trunk unless they're part of a state or US highway.</div><div><br></div><div>Other
 people have suggested just tagging all US routes as trunk, but I don't 
necessarily agree with that because some US routes aren't as important 
as others, particularly when they parallel an Interstate. Also there 
might be some important state routes that could be worthy of being 
tagged as trunk, particularly if they have sections that are four lanes 
and divided, or connect small/medium cities (between 100-500K metro 
population) to each other.  However, if some people feel that the NHS is
 a bit overkill for use as a standard for tagging roads as trunk, then 
I'm okay with just tagging US routes as trunk.</div></div></blockquote><div> </div></div></span><div class="gmail_quote"><span style="background-color:rgb(255,255,255)"><span style="font-family:arial,sans-serif"><font size="2"><span style="color:rgb(29,28,29);font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">I've taken a long look at the<span> </span></span><a href="https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/" rel="noopener noreferrer" style="box-sizing:inherit;font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px" target="_blank">NHS system maps</a><span style="color:rgb(29,28,29);font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none"><span> </span>for my rural region around Vermont (</span><a href="https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/vermont/vt_vermont.pdf" rel="noopener noreferrer" style="box-sizing:inherit;font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px" target="_blank">VT</a><span style="color:rgb(29,28,29);font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">,<span> </span></span><a href="https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/vermont/burlington_vt.pdf" rel="noopener noreferrer" style="box-sizing:inherit;font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px" target="_blank">Burlington metro</a><span style="color:rgb(29,28,29);font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">,<span> </span></span><a href="https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/new_hampshire/nh_newhampshire.pdf" rel="noopener noreferrer" style="box-sizing:inherit;font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px" target="_blank">NH</a><span style="color:rgb(29,28,29);font-style:normal;font-variant-ligatures:common-ligatures;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">, <a href="https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/new_york/ny_newyork.pdf" target="_blank">NY</a>)
