Title: Super low bridge overpass warning signs
Post by: relaxok on March 31, 2014, 02:31:22 PM
Just saw this one over the weekend up in the russian river area in Forestville, CA - What's the lowest you've seen?

Renton, WA; 8 ft. As you can tell, they've taken extensive measures to make sure you don't hit the train overpass:

Sault Ste. Marie, MI - 8'11" railroad underpass (https://www.google.com/maps/@46.501391,-84.363983,3a,90y,271.94h,77.49t/data=!3m4!1e1!3m2!1sFuci1LUKzA7OKfNCt_0BYw!2e0). If you don't fit under, there's luckily an at-grade crossing a block south.

8'6" on Middlesex CR 657 630 in Edison, NJ; low enough for the Bing Maps car to trigger the overheight lights. (http://www.bing.com/maps/?v=2&cp=40.555742~-74.344441&lvl=19&sty=x~lat~40.555742~lon~-74.344441~alt~-0.685~z~30~h~114.6~p~-1.9~cz~0.168~pid~5082&app=5082&FORM=LMLTCC) I also note that the only Google Street View under the bridge was in September 2007, just before the lights were installed, but after the installation of the pole (https://maps.google.com/?ll=40.555711,-74.344246&spn=0.006342,0.027874&t=m&z=16&layer=c&cbll=40.555703,-74.344242&panoid=h_ogG7-HGVR6s_rpNoFJ-A&cbp=11,147.43,,0,-9.77) holding the mast.

Council Bluffs, Iowa has an 8' 8" clearance on Big Lake Road, just east of the county jail where it passes under the Illinois Central (CN) tracks.  The low clearance is bad, but the bigger problem is how often that low spot fills up with rainwater or drainage backup.

I suppose the alternative is just walling up the underpasses that are too short?

My favorite is 11'8" in on NC-1327 in Durham. It has it's own website (http://11foot8.com/) even. Even with flashing overheight sensors, trucks tend to hit it more than occasionally (video (http://youtu.be/xzkWTcDZFH0)).

They need to install a 48x48" Low Clearance warning sign, because evidently current methods aren't working.

Not really. Only 6'4".  I can touch an 8' ceiling flat footed.

I'm 6'0" and flat footed, so I guess your armspan is really wide then. I can't touch the ceiling in my room which is around 8 1/2 inches without standing on my toes and jumping.

How can you even fit in an 8 1/2 inch room?

7'1" is ludicrous.. is that underneath an overpass that is descending to street level in the same spot where the tunnel goes underground?

It's not much lower than most parking garages.  I've been in several that have a height limit at or just above 6 feet.

I didn't think it was a parking garage though.. maybe it is.

It's a street under a bridge. The street goes uphill while the bridge goes towards the ground.

Most trucks aren't even 7 feet tall, so even if it's not, the majority of through traffic (which would exclude semi trucks and buses considering its apparent non-thoroughfare appearance) would fit fine.

Is this one of those artificial height limits to keep trucks (and horses) off the bridge? Seems like the "Strictly Enforced" weight limit, however you enforce that, would take care of the problem.

The first 2 Street Views (the OP and the next one) are amusing if you click the arrows on forward.  The OP's goes from one side of the low clearance to the other, no transition.  The second one, you get up to it, then at the last minute, you only get a backward arrow.  No going on past the low clearance at all.

I wonder if the Googlers have to get out of their cars to do some kind of fold-down of the camera stick to get under really low clearances.  There's one in Longview, TX that it got under, on Green St. by downtown (10', http://goo.gl/maps/6OvOS, with yellow/black 'decorations' ahead of it); several blocks south on Green, another low one, different railroad line (10' 6", http://goo.gl/maps/y830c, no advance 'decorations').  These are the lowest I ever drove by or under.

Yeah, I think the logic behind this one is that if you're vehicle is over 8 feet tall, you're most likely too heavy for the bridge.

I can understand somebody driving a Penske or UHaul truck for the first time in his life and he doesn't realize just how tall the vehicle is, but many of these trucks are driven by alleged "professionals" who should know better than to jam their rigs in a low underpass! :pan:
And there's signs all over the place; there's lights merrily flashing to let them know, "Hey, ding-a-ling, your truck's too tall!"

But wouldn't you want to be a fly on the wall at the dispatch office when one of these drivers gets to explain to his boss, in great detail, exactly how he managed to wreck the rig? :colorful:

Well, in some cases, these "professionals" paid for their CDLs.  It was a big scandal in Illinois not too long ago (http://en.wikipedia.org/wiki/George_Ryan).

Who says they all have limiters?  I've watched trucks going 75-80 mph easily, and those dump trucks (cartage carriers) don't seem to have limiters either.  Can't count the numbers of times I've had them pass me doing 80+.

From the videos on the website, it appears the flashing OVERHEIGHT MUST TURN sign operates erratically.  And that wording comes across as general information and not as a specific warning that YOU ARE (no "if") overheight and YOU must turn.

According to the website, the bridge clearance was raised from 11'8" to 12'4" in October 2019.  It's still had some scrapes (har!) since then.
