Have you checked available rights of way lately? They haven't changed much for quite a while. Telecom has not really any ability to build dedicated bridges for telcom fibre. It uses existing facilities wherever possible. Following the paths of least cost/resistance, this pretty much determines that rivers and bridges become choke-points. The only real alternatives are microwave towers (a cost/benefit argument I won't touch, even with your ten-foot pole). WRT the other comment about that MCI conduit on the tunnel wall, I have reports that temperatures are exceeding 1000F, near the fire. I submit that no amount of armor-clading is going to shield that cable, from those temps. The only cable that might survive is whatever may be buried under the road-bed. > -----Original Message----- > From: Brian Wallingford [mailto:[email protected]] > Sent: Saturday, July 21, 2001 1:28 AM > To: Sean Donelan > Cc: [email protected] > Subject: Re: Update: CSX train derailment > > > > "Rivers and bridges"? > > Either Frank is sensationalizing his comments for the benefit of the > press, or he's been asleep since '93. > > Seems to me the so-called "choke-points" now are more social > and fiscal > than physical - I doubt rivers and bridges are much of an issue. > > > > > > :According to the Baltimore Sun, companies have laid 30,000 feet of > :emergency fiber to patch around the damage in the Howard Tunnel. > : > : "There was a ripple effect around the country with > corporate networks > : due to this Baltimore disaster," said Frank Stanton, an > executive with > : Lexent Inc., a New York-based company that repaired > fiber-optic cable > : after the World Trade Center bombing in 1993.
