No they are (were) very much wrong on West Dempster street.  This was at some point obviously a single bidirectional road, with correct lane and turn lane markings.  It was changed to two unidirectional roads, but the lane markings were not solved when that change was made, resulting in two unidirectional roads with 4 to 6 lanes each, making this appear as an 8 to 12 lane road with random turn lanes all over the plase.  I have resolved this now and will mark it as close.  Please do not close notes if you are not able to verify.  If you are not familiar with lane tagging, please do not close notes about lane issues.  Thanks! Reference this change set:  https://www.openstreetmap.org/changeset/99692192
