Is the detour sign a thing of the past in NJ?

I'm driving to work Wednesday morning ... wait, let's re-phrase that. I'm attempting to drive to work, when the road I usually take is suddenly, inexplicably closed down.

Barriers across both south and north lanes. Nowhere to go but make a left.

This road I take is a more rural road that runs alongside Route 206 and serves as a bypass with fewer lights and a bit less traffic. I can shave maybe three minutes off my commute, usually, by taking this. Not Wednesday of course.

Forced to make the left, I was fairly sure I knew how to cut back over to get to 206 but I put on my GPS just in case. Looking at those roadblocks though, I noticed before I turned that there were no detour signs whatsoever. You were on your own. Not a problem for me, but for someone else, possibly.

Then I thought back to a few weeks ago when Bill Doyle and I both ran across another road closure where you were forced to turn left but in this case there was a detour sign. Problem was ... there were never any others. You would think the definition of a road detour is to direct you sign by sign, but nope. Just a first detour sign with absolutely no followup.

This made me wonder if detour signs are a thing of the past. Are road crews and road departments just deciding that everyone has a working GPS and that detour signs are now unnecessary? Silly if true because so many GPS systems try to reroute you right back to the road closure point. Has anyone else noticed lately that detour signs have become a stingy luxury and not a necessity?

Ah well, with the Transportation Trust Fund running on fumes (pun intended). I suppose roadwork projects will soon be halted anyway.
