When the American Eisenhower interstate system was constructed it was a specific requirement that one in every five of the 46,837 miles of road had to be kept perfectly straight. The idea was that during times of war the roads could be used as emergency runways, negating the need for more airports.

Actually, the 405 freeway in Los Angeles was designed as a backup runway for LAX airport. As far as I know it’s only been used for this purpose once, as documented in the documentary “405″ available at

Fascinating bit of history and snippet of these defence exercises in Taiwan etc.

I wonder in the days of risk averseness and H&S/FOD, whether the RAF would ever be able to practice on one of these roads at all now. Probably would have been a goer in the good old days before PC bollox and the delays it might cause to some chav going to get his benefit cheque.

16000` is about the right length for a Jag in any temp above 2C isnt it!!? :cool:

Why didn't they put the signs on hinges like the palm trees outside the Thunderbird 2 cave?

Salad Dodger, an urban myth. You shouldn't trust your first Google hit.

And in Iraq. One that springs to mind is on the 'motorway' between Basrah and Tallil. I'll try to dig out the pics.

Not quite the same, but the RFDS (Flying Doc's) use roads also - some even have piano keys painted on them (and minimal traffic!)

Isn't the main entrance to Ramstein a standby runway? I'm sure there used to be cable housings there in the late 80s although Google Maps seems to have put a roundabout in the middle. :confused:

Outside Queen Alia airport in Jordan the motorway has all the markings required to become a runway in an emergency too.

Lurking, yes it was, the base PRO told me that after a long hard think they tried it out once but used OV-10s from Sembach up the road, rather than the F-4s that were then based there. Don't know if the F-4s ever used it afterwards. This was in about 1981-82 ish.

Harriers operated from hides in Watton MQs once (Ex Big T) but that was short lived after some garage doors were blown in and the roofs were then blown off. Back to muddy, woody hides then.

i nominate j26 m1, when returning with unused missiles, bombs, napalm, tactical nukes etc, just dump the f:mad:ers on BULWELL:E

Taken whilst serving as Cpl Phot at Command PR RAFG circa 1984. Taking off from a stretch of Autobahn just South of Willelmshaven, prior to the official opening of the road to vehicles. Over a three day period we had RAF, USAF, Luftwaffe, Dutch and Belgique AF landing and taking off from the stretch.

Indeed they have - there are infact 4 in total (1 on the Lemesos-Pafos highway. 1 on the Lemesos-Larnaka stretch just after the Lefkosia split, and 2 on the Lefkosia highway) They were built incase the TRNC decided to come knocking again, with the MOB at Pafos Airport. There are pictures somewhere.....

Interesting thread. Enjoyed reading it - and the first I've read on the mil forum for a very long time where there's been no sniping and moaning. Sweet work fellas! :)

Dont the Swedish Air Force do the same on their roads?

There are loads of them in Sweden, and it's always fun to discover them in unlikely places.
But in recent years some have been taken out of use with permanent central crash barriers being installed after some v. nasty RTAs.

Sweden decided early in the 60s that they would not rely on their peacetime bases in wartime. They then built a lot (30+) of 2000mx40m runways with qra hardstands at each end, and located the lot in Swedens interior, away from the coast. (The "Bas 60" system)
Quite ambitious since they had 21 peacetime bases.)
These bases had hardstands in large clusters connected to the rwy system via public roads, but no road runways.
Peacetime bases was designated as back up sattelites to the war-bases.

With the advent of cluster munitions and precision munitions on the way the SWAF decided that that system was to vulnerable, and during the 80s about half of the BAS60 bases was upgraded to "BAS90" standard, which included building 2 -4 800m road runways connected to the main one via public roads. Dispersed parking along the roads was also added. The use of 800m road rwys was possible with the introduction of the JA37 Viggen aircraft system.

Today, only a handful of the BAS90 bases are active, and some more are on care and maint. Some of the original BAS60 bases are developed into civilian airports today. (Borlänge, Kristianstad, Storuman)

Training as an ATCO in Sweden, i got to try the ATC sim the SWAF use to train controllers in the very special art of controlling tfc from a dispersed base. Very different indeed.

The road bases have created a few entertaining anecdotes, the best one the Viggen that landed on a road RWY at the Byholma base (Road rwy here: http://www.flashearth.com/?lat=56.81....7&r=0&src=ggl, main base to the south east), when he was supposed to land on the main 2000m strip. The road was not closed, and when realizing his mistake, the pilot turned around, and took off in the opposite direction. The driver of the Scania timber truck that he flew over just as he was airborne got the shock of his life. :E

Top thread. Thanks to all.

As for Singapore, the road runway I knew when I lived there in the late 90s was on the East Coast Parkway as it approaches Changi airport after passing the Tanah Merah ferry terminal.

Keen eyed observers would have noticed that all the plants making up the central reservation were in portable containers whereas on the rest of the ECP they were in permanent homes. Markings for when the runway was in use were also visible.

I think they may have tested the runway out just once in my three years there, but -- as usual -- stand to be corrected.

Jags, Strikeys and Hunters used the "Black Top" in Oman, or at least they did back in the 80's. Possibly the Jags and Hawks still do.

The Pease Pottage to Hooley section of the M23 motorway was opened in 1974. Rumour has it that a Jag landed on it sometime just before it opened. Can anyone confirm pls?

The road from Amman to Iraq is designed for use by JRAF in times of need, near the Iraq border.

It's nice and wide and there's a parking area where one would be refuelled.
