I asked a resident who happen to work
in the area re: the 30kft temporary fiber run. See
<http://www.sunspot.net/news/local/bal-traingridlockmap.graphic>
for a map.
It must be in a tunnel. I drove right past there today on
my way to work and didn't see anything at all. The Sun
{newspaper} is on Calvert St. between Center and Orleans.
There are no visible aboveground cables (phone, electrical,
cable) on Calvert or on Guilford for as far as I can see
from the windows right now.
There was a later reference to pipes blocked with mud. Do we
infer they got permission to run it through storm sewers?
In any case, that was fast work by the fiber folks..
