Runaway Truck Ramp located on I-24 in Monteagle, Tennessee. This particular stretch of highway was notorious for traffic accidents because of the steep grade (and was even featured in a Johnny Cash song). Ultimately however the grade was reduced and runaway truck ramps were installed making this highway much safer.

Jerry Reed as well:



He left Atlanta back in '63
hauling him a load to Tennessee
He hit Monteagle in the driving rain
So hard he couldn't even see the passing lane

Well he started down the grade when he lost the gear
He hit them brakes found he had no air
The Monteagle grade is steep and long
And everbody that seen it thought the Bandit was gone

Well his truck jack-knifed turned completely 'round
He was coming down backwards 'bout the speed of sound
Alot of folks seen him and they all say
He had his head out the window yelling clear the way

Well he got to the bottom safe and sound
Everybody asked Bandit how he made it down
He said folks when the truck picked up too much speed
I just run along beside it and drug my feet

I've been driving from Atlanta to Nashville in a 15 passenger van (usually alone) for the last couple of months, and the last time I did it, I finally made it all the way down the eastbound Monteagle grade (four miles, six percent) without putting on my brakes. My speed at the top: 55. At the bottom... 77, not nearly as high as I thought it'd be.

The westbound side is a mile longer and seems a lot less steep. IMO, a case could've been made for swapping the two roadways.

OT: I-24 between Chattanooga and Nashville is a beautiful and fascinating drive, full of interesting stuff for roadgeeks. Hopefully I'll get it together to post a photo feature while I'm still travelling that way regularly.

Wow, this is the first time I've seen this kind of contraption thingy. So, I decided to looked it up on wikipedia and here's what it says:

"A runaway truck ramp, runaway truck lane, escape lane, emergency escape ramp or truck arrester bed is a traffic device that enables vehicles that are having braking problems to safely stop."

http://en.wikipedia.org/wiki/Runaway_truck_ramp

Wow that sounds like cool safety feature especially for emergency situations.

With that said:
I'm kinda surprised why we don't have these things in the Philippines.....

Adelaide also has them on their M1 as it descends towards the inner suburbs, which is particularly significant as the motorway ends abruptly at a set of traffic lights in an urban area. A runaway truck coming down that hill could cause severe accidents, and would very likely continue to plough further down the hill towards Adelaide after the first crash.

Some images from Google Street View of the ramps I mentioned:

M1 at Mooney Mooney, NSW


A32 at Victoria Pass, NSW


M1 near Wollongong, NSW


M1 near Adelaide, South Australia (looking quite a bit cleaner than ours in NSW)

There is one on eastbound I-376 in Pittsburgh, PA, USA:

A runaway vehicle missing that ramp will then pass through the Fort Pitt tunnel, across the Monongahela River and down Liberty Ave, a busy downtown Pittsburgh city street.

A couple of railroad examples in the USA

http://goo.gl/maps/mdJuI

This is at the bottom of a fairly lengthy section of 4% grade on a currently dormant line that is located just southeast of Saluda, NC. The southernmost track is an emergency escape track. When this line is in use, the main track is kept lined for the escape track with a spring switch, which allows ascending trains to pass unimpeded.

Descending trains are automatically timed by the track's signalling system. When a descending train passes a control point at the top of the grade, a timer starts running. After a certain set amount of time, the minimum necessary for a train to make a safe descent of the hill, it automatically lines that switch to the main track to allow the train to continue on its way. Any sooner and the train is directed onto that safety track as a runaway.

Also, here in Appleton, WI, all of the yard tracks at the southwest end of CN's former CNW Appleton yard, which is on a 0.6% grade, are permanently lined to feed into a safety/escape track that directs runaway cars into a small open field. The safety track switch is only lined away from the field when it is being used to move cars, after which it is immediately lined back.

http://goo.gl/maps/xkddO

The safety track is that little spur that is just south of those parked trailers. There is a dormant customer siding that branches off of that safety track, but it has not seen any service in many years.

Here's one just before the Mariannhill toll plaza on the southbound N3 in South Africa:

And in case you miss it there's an emergency lane (noodlaan) at the toll plaza

The descent from Pietermaritzburg to Pinetown is quite steep and the road carries an unusually large proportion of very large trucks, so this is definitely useful!

One that I passed today in Krugersdorp South Africa on the main road to Pretoria (The freeway starts about 500 meter after this):
