Basically, this would be a type of mobile overpass to solve the woes of road construction. It would have to be large enough to hold a decent size construction crew, and strong enough to support your average car (larger vehicles could be directed into the other lane). This way, traffic wouldn't get
clogged up when a two or three lane highway closes down to one.
Not exactly what I had in mind, but think of the pedestrians.

I think you may have an idea here. Not terribly well
written, but I get the basics, I think. |

Some kind of bridge that starts in front of the site, and ends behind it, thus letting cars go over the site? Nice idea. How would it cope with curves? |

wotcha want is a pair of long ramps with a Bailey bridge or the like, spanning the gap. Come to think of it you could add a couple extra pieces to the old Meccano BB set and do it all like that; ramps length determined by road speed. huh... [+] |

A couple of car-transporters in the loading position and a Bailey bridge between 'em. |

For the fast lane, maybe just an up-ramp and a down ramp. with a gap in the middle to fly over ? |

"You must be traveling at at least 100 kph to use this lane....." |

Coulda sworn I annoed and linked to this before work this morning. (+) The military has portable bridge designs that could easily be modified to suit this need. |

sorry for the poor writing. it's not my strong point. And as for curves, that would be tricky, but you could probably send the bridge in sections, and then set it up there. That would be a lot more inconvinent though. |

Forget curves. 93% of roadworks are on straight stretches. |
