In terms of recent construction plans sets from the states that routinely used Clearview on their state highways (a proper subset of those that took out Clearview interim approvals), I am seeing reversion to the FHWA series in AZ, WY, OK, AR, IA, and VA, but not TX. For IL, MI, PA, and OH, I have too little information to make a determination.
TxDOT is by far the largest holdout in terms of annual volume of sign panel detail sheets. It is now making early review plans available online, at completion percentages ranging from 30% to 95%, and the ones that have signing still have Clearview.
In the case of MI I am seeing Clearview signing plans that post-date Michigan DOT's Clearview phaseout memo by more than a year. I can't tell whether that is because they just have a lot of signing plans on the shelf, or if they are counting on being able to change typeface after contract award.
