This sign at Florida Avenue and T Street NW stood under a tarp until Friday, when DDOT director Emeka Moneme and Ward 1 Councilmember Jim Graham unveiled it for a photo op. Nothing new in any of that. But the sign, for some reason, had to be erected twice. “I watched them install the thing once, as I made my coffee, and by the time I got home that night it was gone,” writes Puja Telikicherla, whose house is nearby. “I watched them put it up again, last week.” DDOT spokersperson Erik Linden says he was aware of only one installation.
