Slight correction. That's west Baltimore near Mondawmin. There's a similar bridge just down the WM line crossing North Avenue behind Coppin State.
You're right, because I go east to play softball, in Druid Hill Park from Ellicott City, I mis-spoke.
Ed, thanks for that photo. I am completely clear how the wire passes under the bridge. Now I have to figure out how much clearance that Peter Witt will need. Man, I hope they redo the horrid PCC car while they're in a trolley mood.
