Bulb matrix (Eggcrate) DMS still in use

I was wondering, I would like to know which states still have some bulb matrix (aka Eggcrate) DMS still in use.  The bulb matrix DMS is one of the earliest types of non-static DMS, predating flip-dot, fiber optic, and LED DMS.

I think I remember seeing one in the Orlando area in 2003 displaying the estimated travel times to theme parks, although I can't remember which highway it was on.

GDOT still has a couple in the Atlanta area along I-75, unless they've been replaced in the past year. I see them on the way from Indiana to Florida and vice versa.

NDOT has gotten rid of a lot of the traditional bulb DMS displays. They had several on freeways in the Las Vegas area, but many were replaced during various freeway expansion projects of the last 5-10 years.

The only older displays I know of still around, courtesy of Street View:
* I-15 north, approaching Flamingo Road (exit 38).
* I-15 north, approaching Charleston Blvd/SR 159 (exit 41). This one will be replaced whenever NDOT gets going on Project Neon.
* I-15 south, approaching Spring Mountain Road (exit 39).

There are several of these on I-95 in PA.

Ontario has basically phased them out, though there still are a few of the older style around:
