This bicycle route is missing a name.

The Delaware River Heritage Trail runs along the Delaware River between Palmyra and Trenton. The parking lots named Delaware River Heritage Trail Parking near Princeton are D & R Canal State Park Parking. The trails far away from the Delaware River are probably not the Delaware River Heritage Trail.

Re: Changeset #88116985, Fixed I-287 & I-78 junction

When you fixed the junction you used old Bing aerial imagery. The junction was correct before your changes. See Esri World Imagery, Maxar Premium Imagery (Beta) or National Agriculture Imagery Program.

I can see all the buildings using Firefox, Edge, and Chrome. Have you tried different levels of zoom and then refresh? If you select the Layers icon on the right and then check Map Data you can see that the buildings are in the OSM database. Maybe your browser is slow to display the updates.

Refresh the web page.

You're correct. It looks like Marticville Road was rerouted to bypass the tunnel under the Enola trail. You can edit the newer roads.

Noticed your edits at South Mountain. Did you intend to change several highway=track to power=line? Power lines render as a thin grey line with no name. If your mapping the road used to service the power lines by vehicle then use highway=track. If mapping a bike/foot path and no vehicles then use highway=path which includes horse, bike, and foot.
