Looks like them. The D shaped holes are a tell tale sign. The bark splitting off too. Often, there is stress growth low to the ground as well and branches don't leaf all the way to the tips.
We have an ash tree similarly close to the road which is suffering from the borer. Several more just down the road which are dead and frequently drop potentially deadly branches that block the road. Ours has dropped some too. They just clean them up when they fall and leave the trees to drop more.
We asked our town officials about this hazard and if we could get ours taken down. The marshal said he'd clean up anything that fell, but if we wanted to cut ours, we'd have to pay for it.
Hopefully the DOT where you are is more proactive, but if our experience is any indication, I think you'd need to notify them.
