Are you talking about the overflow reservoirs that have intermittent water in them?

I also compared the plans with recent imagery of new bridge supports and dirt mounds and they do match up. this is the sight with related documentation. https://www.illinoistollway.com/projects The I-490 has multiple pages and document links.

I rechecked the plan, the alignment is correct.

Not really sure what you mean by that.. I can check the master plan again.

I do if I am working on a single task but I wander into multiple details of an area which could take up multiple paragraphs of description if I could actually remember all the items I just added. So adding detail, sums it up quite well. ;-)

the link from off of 190:94 at thin location no longer exists. The new layout for these exits looks like this. https://www.facebook.com/thejanebyrne/posts/953049412289599

part of the Federal-aid highway program. but removed ref for now.

This is a bridged area, not part of hubbers cave nearby.

Please revert this edit. natural=water is the correct way to map water basins in fountains and should not be mass removed. amenity=fountain?uselang=en

When adding path geometry, try using ways and relations instead of blocking out area features. As I fixed the area you made south of Lincoln memorial.

I used "pedestrian area" for these features because of the complexities and vast walkable areas they can cover within the park area that cannot be mapped/depicted with a simple line. The simple path way is also used here for routing services, although that in itself is another topic that is being discussed.

Also incorrect to delete geometry because you do not agree with the way it is tagged. The correct way would be to leave a comment on the relation/changeset and discuss the correct tag to be used.

no

NP. Looks like it is gone now as I rendered new tiles.

The underground building extension was build in 2004 https://web.archive.org/web/20041025102632/http://www.aoc.gov/cvc/weekly/2004/05-24-04.pdf

At the time the road was closed off to local traffic and being used as a detour ramp while another ramp in the circle interchange was being rebuilt.
