Though there is some variety among span wire poles, most to be found fit the following description: Slender, directly anchored into the pavement, and carrying a distinctive ball top (which may also be somewhat acorn shaped).  What can make a span wire pole remarkable is when it has survived extensive redevelopment of an area, where the entire streetscape about it has changed, yet it still stands on duty looking in vain for a streetcar to help power its journey.  Here's a look at a sample of what can be found about town - happy hunting!!!

This pole once powered the streetcars of the #29-Boulevard line, but has since sold out to helping automobiles in their journey.  Nice GE signal though!	Sitting alone looking in vain for a streetcar that has not passed it in over 55 years is this sad pole, a remnant of the #25 line.  It sits just Southeast of Keswick Road and 33rd Street in Hampden.  Photo perspective is looking along the right of way of the old line.
The westernmost surviving pole in the old system stands atop the hill on Main Street in Ellicott City, and is the only such pole to be found there.	Reportedly the last existing actual span of support wire in existence is a signal wire at Frederick Avenue and Athol Avenue in Irvington.  The proof has been hanging there since 1963: a small wooden insulator from which the actual power wire for the streetcars was suspended.
Looking at the back of the shopping Center on Belvedere Avenue at Cordelia, where Belvedere Car House once stood, one sees this pole and attached lamp to offer evidence of the property's former use.	Along the side of the Belvedere property, where now stands a Rite Aid, more distinctive poles offer evidence of streetcar use.  This area was once the terminal loop of Belvedere.
In downtown, crowded sidewalks and a close arrangement made it more advantageous to drill hooks in the sides of buildings and suspend the overhead thusly.  A couple dozen of these loops can still be found in Downtown, such as here on the Kresge's building at Park and Lexington.	This overhead hook is the only one still in use today, though it now suspends support wire for the traffic lights.  It is on the Southwest Corner of Light and Redwood Streets.
