I was mulling around Columbus yesterday, and I noticed a slight change to US23's routing at the south end of downtown. In order to get from High St to the 3rd/4th St couplet, US23 looks like it used to take Livingston (EB) and Fulton (WB) as a couplet. Now, it seems to take Fulton (EB) and Mound (WB) as a couplet. Going SB, here's the signage for the
left turn at Mound (old green signs in the background no longer have a US23 Fulton St sign), and the
right turn onto High. And going NB, here's the signage for the
right turn on Fulton (whose one way has now shifted the other direction in recent years). I don't have signage for the left turn onto 4th, as it's from 2021 when Fulton went one way west, but there are reassurance signs on
Fulton St (wonderful, easy to see placement /s), and the on the first one on
4th St, before Mound.
