Slow spot:

" The area [of I-290] near the I-190 onramp is also confusing and the study recommends re-striping in that area."

One of the commenters hit this one - they had restriped it when they repaved last year. THey removed the surprise merge of the slow lane on 290 and the high-speed lane on 190, gave exiting traffic a separate lane and everything (after a few days of adjustment) started flowing smoother. Then they striped it back to the way it is now and it became a free for all again.
