Like an Interstate. > A trunk is what a motorway becomes when it loses one of it's criteria. Like NY-17 used to be (haven't driven on it in twenty years, so maybe the grade crossings have been eliminated), or like the Taconic State Parkway. > A primary road As is US-11, particularly relative to Interstate I-81. > A secondary road moves traffic within a city. It would service only > a certain area within a city. Mmmmmm, this is somewhat ambiguous. You could have a limited-access highway which only moves traffic within a city; example I-2XX highways. What are the criteria for secondary roads outside of cities? For example, what is US-11B, or US-11C ? They are roads equivalent in quality to US-11, however they are bypasses; are they primary or secondary? > I hope this clarifys things for some users.

The more tags you use to accurately describe a road, the less important becomes the "highway" tag. -- --my blog is at http://blog.russnelson.com | Delegislation is a slippery Crynwr sells support for free software | PGPok | slope to prosperity. 521 Pleasant Valley Rd. | +1 315-323-1241 | Fewer laws, more freedom.
