I fixed this myself in changeset/29766916.

These roads should not be connected. The motorway has a bridge over the smaller road, and there is no way for a vehicle to go between them.

Hi, what's the story behind the part of this change in Burlington? It doesn't seem to fix any connections, just move some nodes and put a weird kink in the road/footways.

You might want to take another look at this, Hutchins Street probably shouldn't be zigzagging like that.

This partially reverts changesets 27171483, 26912045, 26911697, 26910452, 26910130. Among their positive changes, these changesets broke the boundary for Champlain College. There were a number of other negative changes included as well, including some POIs deleted, and building outlines being matched to roofs instead of ground. Both the positive and negative changes were outnumbered by neutral changes, like nodes being moved tiny amounts (centimeters or less). I reverted the changesets, then attempted to recreate the positive changes. Some changes were involved to route relations for US 2 and US 7--I'm not sure reverting kept them correct, but they were very broken anyway, so I will fix their entire lengths in a separate changeset.

Hi,
This looks like an import. In general, imports are supposed to follow the procedure at osm.wiki/Import/Guidelines, which includes things like talking with the community so they can discuss the potential impact, making sure the data is high quality and can be properly matched up with data that's already there, and making sure the new data is licensed in a way that's actually legal to import.

For this changeset in particular, the data seems good, but I noticed a few places where it didn't match up well with the existing data in the map, either because there was a road to the water nearby that the new data didn't match with or because the slipway was already marked and the new data added a second copy of it.

More problematic, though, I couldn't find any license for the data. All I could find was the site's general copyright statement: "This site is protected by copyright and trademark laws under both United States and International law. All rights reserved. © 2011 - 2014, NH Fish and Game Dept." That isn't enough to say it's legal to add to OSM.

I recommend you post on the imports mailing list describing the data and the work you did to add it. This will give the community a chance to look through and discuss the changes.
