Utah: Low-clearance bridge over I-15 to be demolished after semi hits it.
James W Anderson
another truck with a tall load went under it, and struck it.
The bridge is between U-180 (American Fork 500 East) and the Pleasant
Grove Blvd exit. It is known locally as the 'Sam White Road' bridge,
but the street is also known as 1100 South in American Fork as well.
It will be taken down this fall, well in advance of when they
originally planned to. Several trucks struck the same bridge this
year alone. The clearance is only 14' 7". Signs tell you of it going
southbound so you can get off at U-180, I don't recall if I've seen
the same going northbound.
The video associated with the story below shows a shot from the bridge
looking southeast towards Provo/Orem. The semi is in the southbound
lanes and his load is in the northbound HOV lane leaning against the
center divider. I-15 is eight lanes through this area. I went
through this area just tonight.

Standard van height is 13' 6". Why is that bridge a "low clearance" at
14' 7"?

It's low clearance to trucks with big loads. They said this truck was
hauling a load that brought it's height up to 15 feet. And that's a
good 5 inches taller than the clearance for this bridge.

If there are signs announcing the bridge has 'low" clearance, the drivers
who ignore this should be ticketed (in the least). That's like drinking
bleach: there's a warning that the stuff might kill you then if it does, you
wonder why it did that.

In that case, the driver was running on a permit that listed every inch
of the route he was to take. (If he wasn't, why wasn't that mentioned?)
That still doesn't explain the frequent occurrence thing. Yes, drivers
make mistakes, but there is something not mentioned very wrong with this
story.
I saw a funny vignette in central Iowa one day. I had heard an oversize
driver talking to his pilot cars ahead of me somewhere, but I lost track
of them on the radio. By and by I went past them off on the shoulder of
I 80...pilot car, overheight load, pilot car. Between the off-ramp and
the overpass.
I never heard how much the state of Iowa charged them to shut down the
freeway so they could back up to the off-ramp.

Even though he's dead it makes about much sense
to vote for him as it does for the choices
that we have who are living. At least he's not
going change his position on anything.

Interstate standard bridge vertical clearance is 16' rural and 14' urban
with at least one through path at 16'. This was worked out with DOD for
passage of military vehicles. Presumably, everything below 16' on an
Interstate hwy is considered 'low clearance' and should be marked as
such (whether it's grandfathered in from previous standards or allowed
through exception).

bill. The old joke about two [insert nationality / demographic here]
truckers. They're driving a 15 foot load and see a sign "clearance ahead, 14
feet 11 inches". On says to the other "I don't see any cops around, let's
go for it."

Before starting that kind of enforcement, the feds need to crack down on
places where the clearance signs "cry wolf". For example, New York state
routinely understates clearances by a foot, to allow for winter snow
(rather than bother to post changeable signs and/or CLEAR THE SNOW!!!)
When the DOT is known for crying wolf, no one has any business expecting
drivers to believe its warning signs.
