On the Schuylkill Trail near Norristown, there is a electrical utility line that supports a cellular phone antenna site for AT&T - the communication infrastructure at the base of the pole has AT&T branding on it. This location illustrates well the convergence of multiple infrastructure networks, and the co-location of one utility atop another. We have two electrical systems in view, with the line in the center-left of the photograph and more in the background, a railroad track on the left, and the Pennsylvania Turnpike passing overhead. AT&T's cellular antenna is most likely located where it is to support people talking while driving on the turnpike, not for cyclists or pedestrians on the Schuylkill Trail.
