So instead of barges crashing into the piers, you have aircraft hitting the balloons and cables. |
|
| |
This might work until some Saudi millionaire decides the balloons would make a good target. |
|

How about "No bridges"? With a ramp on each side, a minimum speed of 100 km/h and you fly right over. |

[angel] you beat me to it! |

Please, moratorium on helium-related ideas. Helium (or even hydrogen) is crap and can lift very little. Look at the size of an airship that carries 20 people: now how big will the balloon for your bridge need to be? |
|
| |
Perhaps a small hot air balloon and powering it . . . Vernon. |
|
| |
Many bridges are supported from above, they are called suspension bridges. |
|
| |
High winds would make the bridge sway like anything. |
|
| |
Best idea is just to build stronger piers or some sort of device that stops ships from hitting them. |
|
| |
What you want is a ship impact beam. The new Hungerford Bridge on the Thames has one to protect the old railway bridge which it flanks. Apparently it's capable of withstanding 30MN. |

FJ, been watching the Blues Brothers again? |

| |
If we all simply switched to amphibious vehicles this would eliminate the whole issue. |
|
| |
A few rounds from a gun could pierce these balloons. Unless you use some other material. |
|
| |
Stick to piers and normal bridge materials. |

That's a heckuva lotta Minnesotas, there, don'tcha-know. |

London bridge is falling up, falling up, falling up... |
