I guess this would make the most sense, to have permanent detour signs already in place when a road is under construction. Unconventional, but a great way to prepare for the inevitable.

There are some of them in New Jersey, though not always with pentagons.

This is the welcome sign to the State of Pennsylvania for US 6/209 from New York.

Gateway instead of Welcome is most unusual.

Quote from: Plutonic Panda on Today at 08:18:18 PMI'm often wondered if DOTs Fully weigh the cost of full closures Versus setting up a construction zone to let through traffic go through it.

Some areas seem to have viable alternatives that wouldn't add too much time to the route and with a temporary reconfiguration of the road they could move traffic on and off the interstates pretty efficiently. But they still insist on requiring lane of traffic to be open at all times with some exceptions during weekends and nights.

I may be wrong on this, but I think a lot of projects could get done quicker and cheaper, Well, at least quicker, If they did full closures in 24 hour construction work so as long as they're not near residential areas.

IDOT actually does take this into account. There's a part of the planning/Phase 1 part of a project dedicated to traffic management analysis, where they determine what to do with traffic during construction. Other states do something similar. I don't work on that aspect myself, but I've seen these analyses and part of it assigns a dollar value to the construction components, detour signage, variable message signs, and it includes a human cost that assigns a dollar value to a traveler's time.

So they do consider full closures and detours, but it usually takes a really low volume or short detour for that option to be chosen, just because the human cost adds up so quickly.
