Hi; in my changeset/171318302 I reverted the changes marking Coldhams Lane as closed (here and changeset/170726076), in line with guidelines about temporary closures/events at osm.wiki/Good_practice#Don.27t_map_temporary_events_and_temporary_features and construction=* (which says to only tag closures of the order of 6-9 months), for the benefit of offline users and other uses of old copies of OSM data.
While the current ~6-week closure is frustrating, especially now it's been extended to Sep 12, on top of with previous long closures in the past year, it doesn't meet that threshold.

whoops, thanks for catching that!

These roads still aren't open. Did you mean to change this in the globally visible map? I'm assuming not, so I've reinstated the construction tags (in changeset/159783702).

Oh er oops, yes, it should be, shouldn't it? Fixed in changeset/145203228 .

I think this is likely to be incorrect. The helipad moved a couple of years ago -- it certainly wasn't at this location 11 days ago, when I was last at the hospital.
Is this location for the helipad just from Bing aerials? Note that those are now quite old (May 2020); compare Esri World Imagery (Feb 2023), which shows the helipad at its already mapped location to the northwest ( way/596657341#map=19/52.17125/0.13546 ).

I believe access=no was deliberate, so that routing engines that can't use the detailed information in the access:conditional tag don't send people on wasted journeys down here. (https://cyclestreets.net being one such engine)
access=no was needed to override the default assumption that this link is always accessible by foot/cycle: osm.wiki/OSM_tags_for_routing/Access_restrictions#United_Kingdom
Hence, I plan to reinstate access=no soon, if no-one else gets there first.

Similar to changeset/120821700, this deleted a valid restriction relation/5757086, I'm guessing due to a false-positive report at https://www.keepright.at/report_map.php?schema=87&error=77847677 . I've reinstated it in changeset/122949730.

In changelist 122905570, I've restored the relation/5756747 deleted by your changelist; see my comments on your other changelist 120821325 for more detail.
Did you delete this relation because of the issue flagged at https://www.keepright.at/report_map.php?schema=87&error=77847674 ? (Which I have just reported as a false positive.)

This changeset deleted the turn restriction relation/5756748. It's not clear why, so I have just restored the relation as-is in changeset/122870890.
Your change description doesn't describe precisely what the issue was -- I'm guessing it was flagged by https://www.keepright.at/ ?
The restriction type was unusual (conditional), but I don't think it was "missing form [sic] or to way".
(Your changeset/120821700 similarly deleted a relation which I think was valid -- I haven't repaired that yet.)
I guess this was part of https://github.com/microsoft/Open-Maps/issues/79 "Editorial Work in the British Isles"?

Hello. I've been trying to work out this connectivity (resulting in my changeset #115437175), and I'm not sure this change is correct.
While I've no way of being sure what happens underground, there is definitely a large culvert under Newmarket Road from the north end of the East Cambridge Main Drain, whereas the north end of Coldham's Brook on Coldham's Common ends in concrete with a hole no more than a few inches across. And I'm fairly sure the culvert under NMR comes out west of 525 -- I think it can be seen from the Chisholm Trail.
Various sources indicate that Coldham's Brook on Coldham's Common just sort of peters out -- https://democracy.cambridge.gov.uk/documents/s33269/Coldhams%20Common%20Draft%20Management%20Plan%20FINAL%202.pdf (p26) talks about water lost to the Drain through "several swallow holes"; http://www.cnhs.org.uk/wp-content/uploads/2020/02/CNHS2007-ColdhamsCommon.pdf talks about a culvert from the Brook to the Drain.
So I think it most likely that East Cambridge Main Drain south of NMR connects to Coldham's Brook north of NMR, despite the naming discontinuity.

Just a slight shift in the pavement north of either Brownlow or Blackhall Rd -- hard to find it now, I only noticed because of tile caching. Probably not worth worrying about.

This change deleted way/963477405, but it's definitely still there today (and visible on the Maxar Premium imagery), so I've reinstated it (changeset/112814096). Also not sure if some of the changes to Histon Road geometry, which I surveyed on the ground recently after the recent works, are right, but I'll wait for post-construction aerials to re-check that.

Oops, fixed, thanks. (changeset/108322512)
