US 29 at US 90 & 98 in Pensacola at its southern terminus has a mast arm signal assembly. Plus at its north terminus in Ellicot City, MD it terminates at a signalized intersection with mast arms as well.
Any others?
FDOT has a requirement called the Mast Arm Policy Area for intersections near the coasts. In general, all signalized intersections east of I-95 or west of I-75 (south of the Bay Area) or US 19 or 98 (north of the Bay Area) have to have a mast arm wherever there's a signal.
So, US 92 definitely fits here. That also applies to the Florida ends of US 1, 19, 23, 27, 41, 90, 98, 129, 441, and any others that end near the coast.

Not true. US 19 has plenty of span wires itself and most of the Bay Area has span wires west of I-75 and US 19. In fact Hillsborough, Pinnelas, and Pasco seem anxious to lately be installing span wires with fat metal poles. Some parts of Hillsborough now are eliminating the need for two span wires and using one drooping wire with suspenders to keep all at one height. The typical way Florida installs span wire signals is a thin drooping support cable with a level power supply cable below it. However Hillsborough Public Works is copying New York State with the one cable and different length suspenders for their latest.

Hm. I guess that policy area only applies to new signals on DOT roads, so some older ones would be grandfathered in. Or maybe it's just a policy that's codified, but not strictly enforced by reviewers. FWIW, I've never worked with a project where this would even be applicable.
For anyone who might be interested, the rule is in Section 232.8.1 of the FDOT Design Manual (https://fdotwww.blob.core.windows.net/sitefinity/docs/default-source/roadway/fdm/2022/2022fdm232signalization.pdf?).
