The primary function of this connector road is to link Rt 138 with I-195, therefore highway=motorway_link. In addition, the slip roads from this connector are part of this link, even though one way solely connects 138 with Milliken Blvd.

This had been changed 2 or 3 years ago along with a number of other ways in Somerville and Cambridge. Although most of the changes were sound, there are a number in question IMHO. Broadway is given a functional classification by MassDOT as an "urban principal arterial" and is the main road connecting Sullivan Sq. with Magoun/Ball/Powderhouse Sq. in north Somerville. It also forms a continuous thoroughfare from Arlington to Charlestown. A majority of this length was tagged secondary but with seemingly random tertiary segments, this being one of those.

Removed playground from Grand Junction Park. From OSM wiki, Tag:leisure=playground is for an area "specifically designed for children to play," and this area does not qualify.

I changed more now, based on overall inspection of the buildings on each street. All of the downtown streets became unclassified, same if it was mixed use and not purely residential. Please check them. The change area is from Amherst St to Lake St and from Mine Falls Park to Harbor Av. I also changed Temple/Armory/Union St and streets in the commercial areas along the turnpike, like Simon St.

If you like waterways, try mapping Salmon Brook in Nashua, especially where it crosses under Main Street. I worked with it a little, not sure if I got the spillway or the culvert located correctly. Also, its course as mapped is badly misaligned in places, and the brook and its tributaries cross roads and other features without bridges/tunnels.

Sorry, I am used to a convention that tags all highways between “service” and “tertiary” as “residential”, regardless of setting. I will eventually revert what I can to "unclassified". Feel free to change what you want

According to my records, they were evicted in May and closed in August, and you commented in July. My bad.

OK boss

Will do!

I see you changed it back

The toll booths on the bridge were demolished in 2014, and any remaining ones in the entire state in 2016. All-electronic tolling, only gantries over the highways, no booths, no cash

Yeah, unfortunately there is no good tag for conservation land. I have been using "boundary=protected_area" and "protect_class=5" but this will not render on its own. In either case, we could be accused of mapping for the renderer just to make the feature appear.

Typically I only include private residential driveways when there is ambiguity as to which street the driveway comes off or it is long and/or serves two properties. Otherwise, if you draw one driveway, don't you then have to draw all driveways?

Probably was a typo. Since I don't know which object it was on and it does not appear in taginfo any more, I can't fix it

Quincy,
Sorry about the delayed response, I am only now aware of these changeset discussions.
I thought long and hard about this when I changed it, and I am fully aware of the consequences to the map. But I came to the conclusion that the station, IRS building and surrounding streets are all on one large platform suspended over the tracks, and I placed it all on one large "bridge". The expressway and tracks then became surface level. Alternatively, if you make the streets all surface streets, the connectivity with the bridges across the river is lost. Sorry for making such a large change without consulting you or other local users, as I am now finding out is the right thing to do.

Sorry for the delayed response, I was just made aware of these changeset discussions. Yes, that was a typo. Seems that since another editor has changed the node altogether differently!
