Ensure all ways of Northern State are tagged with ref=N.

Remove erroneous refs from unsigned NJ-76C.

Move motorway/trunk transition point on TSP to less arbitrary location. By moving it just south to the US-6 interchange, traffic has a chance to exit before continuing onto the trunk section.

Properly add Croton Gorge Park, and add lots of landuse around it.

Revert poorly aligned geometry changes in changeset 135914459.

Add landuse tags near Croton Dam.

Improve alignment of path to top of Croton Dam. It's hard to make out the southernmost part of the path, so I left it as-is.

Remove descriptive name from path.

Remove ref from Westchester County Routes, as they are not signed.

Downgrade SM Parkway to highway=primary + expressway=yes north of NY-25A, and minor fixes to the interchange there.

Remove access=no from SM Parkway. This tag is not appropriate for such a high-profile, public road.

Downgrade Woodside Ave to primary. expressway=yes is sufficient to convey the limited access construction, and trunk is not appropriate as the road is no more important than the roads it connects to.

Downgrade Rocky Point Bypass to from trunk to primary, and NY-25A Business from primary to secondary. Trunk is not about physical characteristics; the classification should be consistently primary here along the normal route.

Downgrade NY-106, NY-107, and a small part of NY-25A to primary. expressway=yes should be used to denote upgraded construction, not trunk. However, much of these roads has pretty frequent access, so it's unclear whether they are expressways or not.

Downgrade Glen Cove Road to primary. expressway=yes should be used to denote upgraded construction, not trunk. However, much of the road has pretty frequent access, so not all of it should get that tag.

Fix classification of links to Northern Blvd.

Downgrade Northern Blvd to primary from NY-101 to Nassau CR-1. expressway=yes should be used to denote upgraded construction, not trunk. However, this case might not even warrant that tag, since there is still fairly frequent access.

Add lots of detail to TSP/US-6 interchange.

Add expressway=yes to part of Taconic changed to trunk.

Fix alignment on Taconic guard rails.
