preparing the street for new fiber optic cables

Lombard Street in the low 20s, Center City Philadelphia. Near the AT&T communication facility at 500 S. 27th St it appears that AT&T and Verizon-in the center of the photograph you can just make out 'VZ' spray painted in orangeis going to be cutting up the asphalt to put down new fiber optic communication cables. The neighborhood is full of these markings from AT&T, Verizon, and Level 3; I am assuming new communication systems are entering Center City, emerging out of the AT&T communication facility at the corner of 27th Street and South Street.
