MoDOT Rumble Strips

[US71]

It appears MoDOT is now using rumble strips ahead of their construction zones. No warning, they just appear. They are also orange in color. I came across some just west of Mt Vernon on I-44 today. One set, followed by another set about half a mile further down.

Without an accompanying sign indicating something like "construction zone X miles ahead", at least at the first encountered strip, expecting drivers to intuit the situation by the combination of vibration and color seems overly hopeful on the part of MODOT.   But then this is the same agency that eschews reassurance shields for tiny versions on milepost paddles -- so self-evident signage may not be their strong suit!  It'll be interesting to see how this "experiment" pans out!

Well, there are the usual construction zone signs, just no Rumble Strip signage.

Rumble strip signage -- never seen that out here in CA -- and, truth be told, I didn't know such existed, much less was posted anywhere.  I can just see it now:

"That annoying sound you just heard was a MODOT construction-zone rumble strip.  There is nothing wrong with your vehicle.   More of the same ahead!" 

If there is official rumble strip signage out there, I'd certainly like to see some pix!

In Kansas last year, they put rumble strips on I-435 WB near the US69 interchange because people were driving too fast in the work zone. The rumble strips in Missouri is the second time I've ever heard of rumble strips on an interstate.

SB I-75 approaching the Mackinac Bridge toll booths has them. 

Also MDOT often uses them approaching construction zones.

I44 has them on the HE Bailey Turnpike approaching the toll gates.  So does the Kansas Turnpike (I35)

As long as they're accompanied by some sort of explanatory signage, the rumble strip concept is probably a damn good idea; indicating the approach to a toll barrier seems to be a natural!

PennDOT has a yellow warning diamond with "RUMBLE STRIPS AHEAD" where there are rumble strips ahead of a sharp curve in an extreme place.  The one closest to me is the west end of the US 422 freeway west of Pottstown, where it's the end of a freeway, a sharp curve, and a merge all at one place. 

PennDOT used to use them in some freeway work zones, but without a RUMBLE STRIPS AHEAD signage.

NYS DOT does use rumble strips in some freeway work zones...there are some on I-390 in Steuben County.  Here too, without specific warning.

The Illinois Tollway used to have them as you approached the toll plazas (in the days prior to ORT). They have been gone for a while, and I think I-355 was one of the first to do away with them on the Illinois Tollway system (ironically, it was also the first tollway to have I-Pass).
