Mayor Williams and the D.C. Council express optimism that we will--eventually--be thrilled with the results of the installation of new fiber optic cable and telephone lines, despite the chaos it is causing to traffic and its toll on our cars [front page, Nov. 10]. When and how do they intend to address the toll of the process, especially to the residents outside the downtown corridors?

Considering the various cable, telephone, electric, sewer, etc., crews, living in Northwest D.C. is like living in a war zone. The machine gun-sounding pile drivers and jackhammers can start as early as 7 a.m. and go on sometimes until 1 a.m. or later, including Saturdays. Sleep is disturbed, holding conversation on the phone is often impossible, trying to study or create cogent presentations or letters is an exercise in frustration.

While the downtown crews were given a Thanksgiving deadline, what about the rest of the city?

The mayor states that the costs of car damages and snarled traffic will be a small price to pay for improved telephone and cable TV. The price is not small, nor will the costs end when the construction crews leave. We'll be paying yet again, as those companies act to recoup their costs with a monthly service invoice that will continue to rock our world.
