Re: Chances of Comcast extending their cable to me?Couldn't you crane over a steel guide cable, get it to full tension and then just pull the hardline across and never have to interrupt traffic? It's not like a heavy lift where you can't have anything under the lift in case it falls... |

IE some might insist it be closed while the crane is there even if it doens't have hardly any load. |

Debris falling in the road would be bad enough, a steel strand falling in the road would have horrible results. Then imagine if the crane fell. |

I suppose, although they string power lines with helicopters over active roadways... It's also impossible to string the cable with no traffic, as you can shut a lane down, but then you still have a lane of traffic that you're going over, one way or another.... |

Other newer uses like comm lines, water sewer and gas/oil pipelines CAN cross under or use overpasses at their own expense $$$$ |

That sounds like a nightmare and a really stupid idea. That's interesting though about the power lines. They recently did a big upgrade in CT of power lines coming from a nuclear plant over I-95, so not exactly a small project. They flew the guidelines and then pulled the actual wires over with those. |

Other than the helicopter flight alone. Of course for the OP, flying a guide wire for Comcast over would surely put the price into the impractical range.  |

Plus you have to keep insurance on it in case it fails and hits something. This is why the only lines that cross freeways are electrical distribution lines. If anything else is crossing it was done before all the new rules or it was the only way possible to run it. |

Not only are they expensive to build, but the cost for repair (and repair will eventually be needed) is expensive. Sometimes the wires were installed long before that small rural road became a freeway decades later (and got themselves grandfathered). |

These go along with RT. 1, which is on the bridge ahead, but RT.1 was there way before the highway. » www.google.com/maps/@41. ··· 2!8i6656 |

that looks like a temporary that is waiting for a fly over to connect 395 and 1. it might work there but major interstates with 3-5 lanes a wide median and room for expansion isn't going to do it a simple wooden poles, you need to thing engineered steel towers, BIG cables etc.
nobody is running single drops or a few fibers across that for anyone |

Phhh, that's nothing. This one was fixed before the freeway was widened a few years ago. In fact, it had been damaged by a fire due to the freeway construction. The splice case over the 2nd to right lane used to be the shoulder of the frontage road. The span now crosses 14 freeway lanes, shoulders, and 3 railroad tracks. That splice case is never going to be touched again.

Those utility poles are NOT temporary, they've been there for many years. I would imagine, however, if the state ever finishes Route 11 and builds a new interchange with 1, 395, 95, and 11 (which they have a plan for just like everything that never gets done), they will route the utilities with Route 1 or in an UG conduit. |

Right, but in the OP's case, it's a rural 4-lane interstate, not that mess. |
